Halogen Vs HID Vs LED Headlights, Which Headlight Is Better?

Recently we heard a lot about halogen vs HID, halogen vs LED, HID vs LED headlights, which one is better? Since the first car was made, manufacturers have been looking for ways to improve their products in every way possible. Perhaps no component on a car has more significance than its headlights. After all, lights are important to safety on the road. They make sure that you can see the road ahead, even at night, or during low-light situations. And they also make sure that other road users see your car.


Why don't automobile manufacturers make use of LED for headlights?

You will notice several important differences in light produced by LEDs, xenon and halogen headlights. LEDs have the coolest color temperature at around 6,000 Kelvin, which makes them appear whiter than daylight. Xenon headlights come in at around 4,500 K, while halogens round out the list at a yellowish 3,200 K. nnnWhen it comes to reflection, LEDs offer better light return from road signs, while xenon lamps better illuminate the sides of the road. In part, this is because xenon lamps typically produce more light, measured in lumens, than LEDs.Both LEDs and xenon provide a large pattern of light on the road, whereas halogens offer a small pool of yellow light directly in front of the vehicle. If you are buying a new car, expect LED headlights to be the premium option, and make sure your auto repair shop is equipped to handle LED headlight replacements and repairs.If you are looking for intense light and do not mind the glare, xenon may be the best choice. LEDs, meanwhile, offer great light, low power and long life, but often come with a bigger price tag. Halogen headlightsnHalogen lights are the most popular lights on the market and are found in most consumer cars. These bulbs are similar to familiar incandescent lights and use heated tungsten filaments to produce light. ProsnThe main benefits of halogen bulbs include low replacement costs and longevity. ConsnHalogen headlights produce a significant amount of heat, and even small deposits of skin moisture on the bulb during replacement can affect their performance. Xenon headlightsnXenon lights, also known as high-intensity discharge (HID) lights, produce a brighter light than halogen bulbs and with far less heat. The blue-white light emitted by xenon bulbs is so bright, it has been known to "blind" other drivers. nProsnThese headlights require a large amount of power at the outset to produce their first burst of light, but once fully operational, they require much less energy to maintain constant brightness.nXenon bulbs have a long lifespan and emit little heat.ConsnThey cost more than halogen bulbs.nLED headlightsnLEDs are the most recent innovation in headlight technology. Instead of gas and filaments, LEDs rely on small diodes that produce light when electric current excites their electrons.nProsnThey need an low amount of power to work but do produce a significant amount of heat on the diode. The small size of LEDs means they can be formed into almost any shape, and their light is naturally directional rather than diffuse, making them an excellent choice for headlights. nConsnRequires cooling system to prevent led diodes from burning out.nSo,conclusion here is:nLed headlights are not cheap.Maintenance cost are higher and requires skill. Extra equipment required to help keep lights cool to prevent burnout.Thats why LED lamps are not preferred in mid range vehicles.Expensive cars might get Led headlamps.Why do not automobile manufacturers make use of LED for headlights?.

What are some of the dangers with using LED headlights on a vehicle?

some of the dangers:Dazzling oncoming drivers because the LED is too bright / too white / dazzlingPutting LED in a headlamp that is designed for halogen bulbs (H1 / H4 / H7) will throw a different pattern of light onto the road. If the car was designed with a halogen headlight the patterns in the headlight lens and reflector will optimise the pattern so as not just to blind other oncoming traffic but also give you the driver the best possible beam in terms of brightness/width/height to drive with (be it low beam or high beam)If you use headlamps or bulbs that were not designed for the vehicle when you bought the vehicle by the OEM (factory fitted) then when you take your car for a road worthiness test (NCT in Ireland / MOT in the UK .. I dont know what it is called in other parts of the world) - when they test your headlights it will fail if the LED bulbs are too bright , they will fail if they are too dim, they will fail if they are too high up or down low, they will fail if the beam pattern is not as it should be...What are some of the dangers with using LED headlights on a vehicle?.

Do LED car headlights pose any health issue as it generates electromagnetic radiation? I sometimes hear radio interference when the LED headlights are switched on. Does this pose a health problem for the passengers inside the car?

Nope, zero risk. Often LED lights are pulsed with high current for short brief periods of time at a higher frequency than the persistence of our eyes, which is maybe 120 times per second. But at that low rate a strobe effect would be detectable at night when looking from side to side, so LED flashlights and other LED illumination sources are pulsed at a relatively high frequency of maybe 3,000 or 4,000 Hz, meaning 4 KHz, or 4,000 pulses per second. Who knows, some LEDs could well be pulsed slightly above audio frequencies which is above 20 KHz. In any event, it's a minor concern because all those frequencies are significantly lower than radio, television and cell phone frequencies. There is a little concern about those high frequencies but I have never heard of any concern about low frequencies at audio and below. I'm ignoring for a moment the super low frequency 60 Hz concerns from people who live near high voltage power lines. That's a different story. Another important fact that makes LEDs a non-issue for cars is this. Typically a car is made of steal or aluminum and it acts as a Faraday Shield, so basically impossible for any radiation to reach passengers in the car. The headlights are lower than the hood and any radiation can't find a line of sight path into the cabin through the windshield. Exotic cars with carbon bodies won't block radiation but the frame and other metals would block a lot of any radiation that might be present. And there's almost radiation no to begin with. Faraday cage - WikipediaIf you ranked risks in terms of seriousness and probability there's a long list that might go approximately in this order: Global Warming, flu, cancer, disease, sickness, murder, struck by lightning, Earth hit by another dinosaur size meteor, and then maybe a million other obscure possibilities... I'm still not sure EMI radiation from LEDs of any kind would even be on the list in millionth place. Do LED car headlights pose any health issue as it generates electromagnetic radiation? I sometimes hear radio interference when the LED headlights are switched on. Does this pose a health problem for the passengers inside the car?

Is it normal for LED headlights to be in a straight line light pattern from left to about half of the passenger side and then goes up about 45 degrees? I have been trying hard to make the light pattern in a straight line, but it's not working.

That's normal. The flat top is so the headlights don't shine directly at oncoming traffic- there's a slight downward angle to this cutoff. The angled kickup towards the edge of the road is intended to illuminate roadsigns and other things by the side of the road. The 'break point' where the flat top ends should be aimed directly ahead or slightly towards the roadside- never into traffic. The pattern will be reversed for countries driving on the other side of the road. British drivers taking their cars abroad have to fit deflectors to adapt the headlight beam.Is it normal for LED headlights to be in a straight line light pattern from left to about half of the passenger side and then goes up about 45 degrees?

Isn't Toyota Innova and Fortuner overprized as they lack features like sunroof, digital mid, LED headlights, and other things?

Toyota makes the most reliable car. They leave out the stuff that causes future problems. They design the parts in their cars to be reliable and last longer too.So, if you just want a boring car that always starts and gets you to where you want to go with the fewest problems, buy a Toyota car. Toyota Corolla is a great example of a car that lasts for 200K miles or more and is very reliable too.Internet search "utube Here's why the Toyota Corolla is the best selling car of all time".Always have a auto mechanic from a different business check out the car before you buy it. Other Toyota cars are very good too. Do research because even Toyota makes a few bad models once in a while.Some of the newer Toyota cars are having early parts failure now. Water pump failure, fuel pump failure, brake master cylinder failure and cracked engine block. Avoid the CVT transmission in the nonhybrid Toyota Corolla.In the long run, a Toyota car should cost you less because of fewer break downs. Think total cost over time.I am not an expert in the stock market. But I have gained this knowledge from other well known people who do understand when to buy and sell stocks.

Do you think super-ultra-bright LED headlights make roads safer or less safe than "old-school" style headlights? Why or why not?

Overall, no - because they're not used properly. With LED lights, HID (High Intensity Discharge) lights, etc., if you retrofit those to a housing which originally had incandescent bulbs in it, you're emitting several times more useable light than what they were meant for. It can still work, but having the headlights properly adjusted is imperative.Of course, the alternative is projector headlights, which does more to harness it, but also reduces the field of light.The other thing I don't like about LED headlights is the color temperature - LEDs tend to be white, which gives the most useable light, but yellow is really much better for fog. Naturally, being able to better see the road ahead of you is a good thing. Doing it to the detriment of other drivers isn't.Do you think super-ultra-bright LED headlights make roads safer or less safe than "old-school" style headlights? Why or why not?.

When would US ban LED headlights on cars? They are just too bright.

LED's are a boon to drivers as they don't grow dimmer with age as incandescent or even HID (High Intensity Discharge that creates a blueish light). By and large, I don't find them to be overly bright except for a few car makers who haven't quite figured out how to keep the light scatter down.This extra scattering of the light will eventually be tamed as the technology advances. I would say that most of this "blinding light" you see is because of drivers who haven't quite figured out how to switch from "HIGH" beam to "LOW".Also thrown into the mix are kids who buy LED conversion kits for their cars because they look so "cool" but don't have the common sense of having them aimed professionally.When would US ban LED headlights on cars? They are just too bright.

What is the difference between Hid and Led headlights?

HID (High Intensity Discharge) are normally much brighter than standard halogen lights (the luminosity is greater providing much higher foot candles). They work by heating xenon gas (an inert gas) within a small chamber. This is why they are so bright. But they require a special ballast in order to convert the 12V DC current to a much higher level to ignite the gas. This is also why they are so expensive. Normal halogen lights work by heating a filiment within the bulb and reflecting the light forward. LED (Light Emitting Diodes) are basically diodes that become heated and glow. Unfortunately they are not very bright. However they glow white or bluish-white which looks pretty cool and they last a very long time using only a small amount of energy. As far as headlights are concerned, you will never find an LED headlight with the LED being the main light. LED headlights will always have a HID or halogen main bulb. The LED will usually be a ring around the projector lens (known as HALO lenses) or will have a line of LED lights below the main lights (look at the new AUDI). Basically HID is a very bright headlight and LED is a headlight accessory (makes it look fancy). Hope this helps. BTW - I own a professional headlight restoration company so I deal with headlights every day.

Do LED headlights in cars use PWM or just a constant voltage to operate?

Most of the time, no. 99% of all light functions use constant DC supply. The main exception is if there is a lamp that is simultaneously used as a daytime running light and position light, and when PO function turns on, it uses the same current as DRL, but with PWM applied on top. Even then, the PWM is usually supplied as an external signal that drives the transistors in series with the LED. PWM will also sometimes (but rarely) be used to reduce thermal load at high ambient temperatures.Do LED headlights in cars use PWM or just a constant voltage to operate?

Do you like the newer LED headlights or the regular headlights more?

I hate the new ones. They pierce through my retinas right into my soul. The old ones are way better and I do not feel like a deer caught in the headlights

Switching From Halogen to LED Headlights
Changing out headlight bulbs is a complicated process in some vehicles. If you replace a halogen bulb, experts warn you not to touch the glass enclosure of the bulb. Grease and other debris on your hands can transfer to the bulb glass. When that greasy or oily coating heats up, it can damage the halogen bulb and reduce its life span.9 Different Types of HeadlightsCar headlights do not need an introduction. They are what keep the road illuminated for you while you are cruising on the streets late at night. It is your car headlights that keep you from bumping into a tree or running into someone after the sun has set. All cars, old or new, have headlights installed. The law has made it mandatory to have both the headlights of your car in working condition. They not only ensure your safety while you are on the road but also the safety of pedestrians and animals crossing the road. Back in the old days, all cars came with similar headlights, but today, where newer and more technologically advanced vehicles have been introduced, the types of headlights also vary. Newer models of cars have newer and cooler headlights installed. You may think that all headlights are the same, but actually, they are not . And we do not just mean different in terms of design only. They are also different in terms of operational mechanisms. If you ever have to get your headlights replaced, you should at least have sufficient knowledge about the type of headlights your car has and the types of headlights you can replace your existing lights with. Headlights are one of the most important parts of your vehicle, and they sure deserve some attention. We will be dividing the types of headlights into three sections: Types of headlights based on the headlight housing Types of headlights based on the number of bulbs Types of Headlights Based on the Headlight Housing The is the 'house' where the bulb of the headlight resides. In simpler words, it is the case that accommodates the headlight bulb. The headlight housing is not the same in all cars. The way a bulb is mounted and where the bulb is situated varies. were the standard headlights that were present in all vehicles till 1985. These are still the most common types of headlights that you will see. The bulb in a reflector headlight is encased in a bowl-like case. The bowl-like case has mirrors installed that reflect the light onto the road. These headlights that were found in older cars had a fixed casing. This meant that in case the bulb burned out, it could not be replaced, and the entire headlight case had to be changed. These reflector headlights were also known as the sealed beam headlights. In sealed beam headlights, there was a lens in front of the headlight which determined the shape of the beam of the light that was produced by them. However, newer reflector headlights come with mirrors inside the housing instead of a lens. These mirrors are used to guide the beam of light. With this technological improvement, there is no need to have a sealed headlight housing and bulb. It also means that the bulbs can be replaced easily when they burn out. These headlights are smaller in size, and therefore, take up less space within the vehicle. The light output in is less controlled, and therefore, high output light bulbs cannot be used with this type of headlight housing. The low beam cutoff is less distinct for oncoming traffic. The beam of light often has weak and intense spots. With improvements in technology in the headlight industry, headlights got better. Projector headlights are a newer type of headlight that was first used in the 1980s in luxury cars only. However, today, projector headlights have become quite common, and most of the newer models of cars come equipped with these types of headlights. Projector headlights are quite similar to reflector headlights in terms of assembly. These headlights also consist of a bulb that is enclosed in a steel case that has mirrors. These mirrors act as reflectors, just like they do in reflector headlights. The only difference is that projector headlights have a lens that works like a magnifying glass. It increases the brightness of the beam of light, and hence, projector headlights produce better illumination. To make sure that the angle of the light beam produced by projector headlights is correct, they come with a cutoff shield. It is due to the presence of this cutoff shield that projector headlights have a very sharp cutoff. Projector headlights are brighter than the old reflector headlights. They do not shine into the eyes of the other drivers on the road. This is because the lens projects the beam of light downwards onto the road. The benefit of this is that projector headlights do not blind other drivers or pedestrians who are crossing the road. The beam of light produced by projector headlights is a lot more even, with no weak or intense spots. Projector headlights can have HID bulbs, unlike reflector headlights, which can only house halogen bulbs. The output of light with projector headlights is a lot different than reflector headlights. If you are too accustomed to the light output of reflector headlights, you may find it hard to get used to projector headlights. If you wish to upgrade the headlight system of your car, are a cost-effective way of doing so. It uses the standard reflector-type housing, but instead of a sealed case, they use an H4 dual filament type bulb that can be replaced. This means that if your bulb gets burned out, you do not have to get the entire casing replaced. You can simply replace the bulb and be on the road again in no time (or as long as it takes your mechanic to replace the bulb). This also opens up the possibilities of using brighter bulbs like LEDs or HIDs. Since H4 conversions are a standard reflector-type, the light beam they produce is uneven with hot-spotting, a scattered light output, and possible blinding of oncoming traffic. Types of Headlights Based on the Number of Bulbs Headlights are divided into two types on the basis of the number of bulbs housed in the headlight housing. Quad headlights are the headlights that have two bulbs in each headlight. Non-Quad headlights have a single bulb in each headlight. Quad headlights and non-quad headlights are not interchangeable because the wiring inside is specific to each type. If your vehicle has quad headlights, that's what you can replace your headlights with. The same is the case with non-quad headlights. There are four major types of headlights based on the type of bulb being used. They are: Headlights with are the most commonly found headlights in most cars on the road today. They are an improved version of the sealed-beam headlights. The older headlights used bulbs that were basically heavy-duty versions of the regular filament bulb you use at home. Regular bulbs consist of a filament suspended in a vacuum. The filament lights up when electricity passes through the wire and heats it up. The vacuum inside the bulb ensures that the wire does not get oxidized and breaks. Although these bulbs worked well for several years, they were quite inefficient, always hot, and gave a yellowish beam of light. Halogen bulbs, on the other hand, have halogen gases filled inside instead of a vacuum. The filament is almost the same size as the bulb of a sealed beam headlight, but the gas tube is smaller and houses a smaller volume of gas to contain the heat. The halogen gases that these bulbs use are bromine and iodide (in combination). These gases ensure that the filament does not thin and break and also reduce the blackening that usually occurs inside the bulb. The filament burns much hotter as a result and produces a brighter light. The gases get heated up to 2500 degrees. They last for a longer time. Halogen bulbs are small in size, and therefore, take up less space within the vehicle. They are easy to replace. Headlights with halogen bulbs are definitely superior to sealed-beam, reflector-type headlights. Among the newer headlight options that are available today, halogen headlights are the most affordable. The beam of light is slightly yellow in color and does not cast further ahead. HID stands for . They are also known as Xenon headlights. HID bulbs employ completely different technology to that of regular bulbs. These bulbs put HID headlights firmly in the category of headlights that provide the farthest visibility to the driver. They are getting popular by the day, and more and more people are switching to HID headlights for all the right reasons. Unlike sealed-beam and halogen headlights, HID headlights do not contain the usual filament bulbs. They produce light when an arc of electric power passes across a pair of electrodes that are trapped inside a glass tube. This glass tube is filled with xenon gas. We said earlier that HID headlights are also known as xenon headlights; well, due to the arc of electricity that powers these headlights, they are also known as Arc headlights. Along with the xenon gas, these bulbs also contain vaporized metals like metal halides and mercury. The passage of electric current through the arc melts the vapors of the metals and converts them into plasma. Hence, HID headlights also have another name (although, a less common one) - Plasma headlights. It is the plasma that glows in a shade of white-blue that produces the brilliant light that these headlights are so famous for. A reflector is present within the headlight assembly that bounces the light onto the road. The light that is produced by HID headlights is extremely intense. It offers versatility, and you can adjust the focus as per your need. You can focus the beam of light into a narrow beam that extends far out in front of the car, or you can set it to a broad beam that fills the area that lies directly ahead. HID headlights produce extremely bright light in the spectrum of white-blue. HID headlights offer greater vision well down the road due to the longer wavelengths they use, and lesser scatter as compared to yellow-lights (as in halogen and sealed-beam headlights). As there is no filament to burn out in HID bulbs, these headlights are more likely to last longer. HID headlights are slow in turning on. HID headlights take several seconds to warm up and come to their maximum brightness. They can irritate drivers that are in oncoming traffic as the white-blue light that HID headlights produce is strikingly bright. Light in the blue-white spectrum can significantly affect the night vision of a person. Light from HID headlights will not only blind other drivers but can also hamper their vision when it comes to seeing anything that is dimmer (including the tail lights of the vehicles ahead). This way, HID headlights can be a cause of accidents. What is worse is that it's not just the night vision of other drivers that are affected; your vision will also be affected. You will be able to see everything ahead very clearly, but you will be almost blind to anything that is outside the spread of the light beam. As far as the performance is concerned, HID lights remain unbeaten. However, they do come with a set of some nasty side effects, including an increased risk of accidents. The bright, white light and longer lifespan have made LED bulbs quite popular to be used in car headlights. LED stands for Light Emitting Diodes. The potential of LEDs as car headlights is massive. LED bulbs are highly efficient, compact, and can turn on and off instantly, which gives them an edge over HID headlights. The tiny semiconductors of LED light bulbs can produce a wide array of focuses and light levels at an exceptional speed (within nanoseconds). LED lights, like HID bulbs, do not work on the principle of a filament. They convert electricity into light via the diodes that are present inside the headlights. The process by which LED lights convert electricity into the light is called . The process is highly energy efficient as compared to the process that is employed in halogen headlights. Little or no heat is produced, and this improves the lifespan of these bulbs incredibly! The LED technology is still quite new, and therefore, not all cars using LED headlights have all the features. For example, the high and low beam settings of LED light are only available in high-end and hybrid vehicles. Although LED lights do not get heated up, there are certain heating issues that LED headlights are associated with. The is quite high, as a result of which, the emitter chip base gets very hot. The LED light needs a sink where it can release the heat. Otherwise, the diode would melt. This makes the system complicated and expensive. They are small and compact. LED lights take up a very small space within the vehicle. They are so small that they do not even need a headlight house. But, of course, that would change the entire look of the vehicle. LED headlights can be turned on and off instantly. They do not blind other drivers. These headlights do not only focus on what is directly ahead but also offer a wider area of vision as well. LED lights can use any color spectrum. They are not limited to the bright, white-blue spectrum. They are more expensive as compared to HID headlights. If you think involve two piercing lasers that can melt the eyes of an oncoming driver, you can relax because laser headlights are anything but blinding. Laser headlights are the new hot thing in the automotive industry. They can produce light that is a thousand times brighter than LED lights without requiring as much power as LED lights need. The laser system uses three blue-colored laser beams that are directed into a chamber that contains yellow-colored phosphorus gas, which is phosphorescent (glow-in-the-dark). Phosphorus does not store light to release later but produces light as a result of a chemical reaction that occurs within the chamber. This chemical reaction is sustained by the laser beams and is captured inside the chamber. Therefore, what you see is not actually the light from the laser beams but the glowing that is produced by the phosphorus. Laser headlights can produce about 1000 times brighter light in almost half the power that LED headlights use. The beam of light can focus up to an incredible 2000 feet. Laser lights burn in the range of 6500 Kelvin, which is about same as the natural daylight and LED lights. They can flash on and off instantly. Laser lights are very versatile and can be made into different shapes and designs. Laser headlights are way too expensive (being offered by BMW as an add-on for $10,000). Laser lights are not expected to replace LED lights in ancillary applications like brake lights and turn signals. Laser lights produce a lot more heat as compared to LED lights, and thus, they will need more cooling. After looking at all the types of headlights thoroughly, we can say that LED lights are the current leader in the automotive lighting industry. Laser headlights cannot be beaten when it comes to performance, but they are not yet commercially available, and the whopping cost makes it almost unapproachable for mass production. LED headlights, on the other hand, not only offer the brightness that is needed but also ensures that the other drivers on the road are not irritated. Although they come at a higher cost than other types of headlights, LED headlights are surely the best option that most people are turning to. Tips for Choosing Headlights for Your Car Now that you are well aware of all the types of headlights, you can decide which headlights are the best for your vehicle. Before you leap into replacing your car headlights, ensure that you check the pros and cons to see if the replacement is worth it. Below are a few tips that may help in making the selection. Select the headlights that produce a beam type that you want - spot, flood-wide, or flood spotlight. Headlights are available in numerous designs. When choosing new headlights for your car, make sure that you select a design that not only looks good alone but also looks good on your car. If you are planning on getting new LED headlights for your car, the color selection should be made as per your wishes. White light is an ideal option. One of the most important considerations when getting the headlights of your car replaced is the cost. You will find car headlights in different price ranges. Select the one that falls within your budget. Selecting the cheapest option is not recommended. To ensure the road safety of yourself and others, having the right headlights is very important. The headlights of your car have an impact on how well and how far you can see around. The wider the spread of light, the safer you and others are.
2018 Porsche Panamera Executive: Hire the Chauffeur
"Fire the chauffeur" was the punchline of a popular 1980s Porsche commercial, in which a proud owner enjoys driving his new 928 S4 so much that he asks his butler, Charles, to terminate the employment of his chauffeur.But here's a new Porsche that is designed for those who would rather be driven.The 2018 Porsche Panamera Executive is a long-wheelbase version of the Panamera, targeting customers who like to be chauffeured around.It's available with all engines and represents the second of three Panamera body variations. (The third will be a station wagon, to be called a shooting brake, built using the regular wheelbase but it will be another year before that derivative hits the market.)Porsche's new, second-generation Panamera family also is expanding in the opposite direction.Marking the new port of entrance is the base Panamera, which is powered by a 330-hp 3.0-liter turbocharged V-6 and slots neatly under the Panamera 4S. The base car will be called simply the Panamera when fitted with rear-wheel drive, or the Panamera 4 with all-wheel drive.The new single-turbo engine is closely related to the 440-hp 2.9-liter biturbo offered in the Panamera 4S.In essence, this is the engine offered in the new Audi S4 and S5, but here, it's mated to an eight-speed dual-clutch automatic transmission.In the rear-wheel-drive model, zero to 60 mph takes just 5.4 seconds (according to Porsche), and it tops out at an ungoverned 164 mph; the Sport Chrono package shaves another 0.2 second off the standard sprint. With all-wheel drive, acceleration improves further.The Panamera Executive will be available with all the engines you can get in the standard-length model, including the new entry-level powertrain.What you cannot get is a Panamera Executive with rear-wheel drive; all-wheel drive is standard on the long-wheelbase version.The Executive comes as the Panamera 4 with the aforementioned 3.0-liter V-6 turbo and 330 horsepower, the Panamera 4S with a 2.9-liter twin-turbo V-6 and 440 horsepower, the Panamera Turbo Executive with a 4.0-liter twin-turbo V-8 and 550 horsepower, and as the Panamera E-Hybrid Executive with a V-6 plug-in-hybrid powertrain and total system power of 462 horsepower.Lengthened by 5.9 inches and heavier by around 200 pounds, the Executive models suffer only a slight performance penalty. Top speed remains unchanged, and the claimed zero-to-60-mph times increase by only 0.1 second.Fuel economy is almost identical in Europe-market tests.At a total length of 204.7 inches, the Panamera Executive is not exactly compact.But it may be the most nimble and agile luxobarge out there. We've admired the regular Panamera's handling prowess, and Porsche's adaptive damping system (PASM) is standard here.The 4S and Turbo versions of the Panamera Executive also come with standard all-wheel steering, which should make the car handle even more nimbly and decrease the turning circle.There are some comfort-oriented goodies on board as well: Heated, uplevel "comfort seats" with multifarious adjustment options, an electric rear-window sunshade, and a panoramic sunroof are all standard on the Panamera 4 Executive.The 4S Executive gets soft-close doors as well; and the Turbo Executive tops it off with an ambient interior-lighting system, four-zone climate control, and uplevel LED headlights. It makes for a pretty comprehensive list of standard goodies, although the options list will let you plunk down tens of thousands more.Even the regular Panamera is graced with a surprisingly spacious rear seat.The Panamera Executive easily reaches the level of the BMW 7-series and the Mercedes-Benz S-class.We like the harmonious look of the new Panamera Executive, and it has been achieved with little compromise. To make sure your neighbors notice, there is a chrome badge on the C-pillar.The new entry-level, short-wheelbase Panamera will set you back $86,050, while the all-wheel-drive Panamera 4 costs $90,650.The long-wheelbase Panamera 4 Executive retails at $97,350, and the Panamera 4 E-Hybrid Executive is priced at $105,150 ($4500 more than the short-wheelbase Panamera 4 E-Hybrid).Pricing for the Executive derivatives of the 4S and Turbo versions has not been announced yet. The first batch of new models will be delivered starting in January 2017.And your chauffeur will be pleased to get behind the wheelLED Headlight Beam Pattern: A Guide for Beginners – LoganTDSAutomotive light technology has many terminologies. And beam pattern is just one among the many. Find out more about headlight beam technology and how it affects the headlight's functionality. If you have been browsing reviews and tips online on how to find a high-quality LED headlight, chances are you've come across several terminologies that you never knew before. One of the basic terms you will encounter is beam pattern. One of the elements you need to consider when buying a car headlight is beam pattern. It is perhaps the trickiest factor when purchasing headlights online. Of course, it is impossible to know the headlight's beam pattern until it arrives at your door. It is why reading product reviews of potential options, such as this Hikari LED headlight review, is very helpful. It reduces your chances of purchasing an LED headlight with a poor beam pattern. Every light source has a light pattern. For example, flashlights have two beam patterns known as throw and flood. In headlights, most automotive features a focused beam pattern is known as DOT. It is commonly used in North American vehicles. The pattern is apparent among projector-style headlights. In a DOT pattern, the illumination has a focus and sharp cut-off. This feature allows the headlight to produce less intense brightness. Hence, you can drive without blinding the oncoming drivers with this type of beam pattern. Therefore, there is minimal risk of road accidents. Light Intensity and How it Affects Visibility Upper cut-off in headlight illumination is a crucial factor in keeping drivers safe and in circumventing road accidents. However, one should take note that the amount of light in an output pattern is also vital. A focused and small hot spot at the upper center of the beam pattern supports long-range visibility. It allows you to notice oncoming vehicles and objects. If the light intensity is higher around the middle, the light is thrown directly in the road creating blinding light projection. Likewise, it reduces long-distance vision, which is crucial in driving. In a nutshell, a headlight's beam pattern directly affects visibility and safety on the road. A good rule of thumb is to select a headlight with focused illumination and sharp cut-off since this type of beam pattern has a lesser risk of road accidents. If you are planning to upgrade your headlight, do plenty of research before finalizing your decision. Consider the vital factors when buying headlights, such as the item's level of brightness, beam pattern, type of reflector, and durability. And to make the right choices, always take into account the effects of factors on safe driving. Talk about your planned light upgrade and ask for assistance. In this manner, you can guarantee the right options and avoid spending money on poor headlights. For online purchases, send your queries to the seller. You can also look for reviews from reliable online sources. Take note that it is trickier when buying online. Thus, avoid impulse purchases, you should take time to learn more about the item to find out whether it is a good investment.

Can it pay in gold coins and bars?Can US dollars be replaced with gold in 2020 for international trade like a country does not have dollars to buy other country's goods? Can it pay in gold coins and bars?There is not enough gold in the world to handle the huge dollar volume of transactions. Theoretically it could happen by raising the price of gold about 100 fold or so. Then each country would give its gold out to it's citizens in return for their holdings of that nation's money. In the Eurozone, Euros would be exchanged for gold.After that was done, then people would buy and sell things for milligrams of gold. But it would be very unfair and inefficient, because the distribution of gold ownership, around the world, is very different than the distribution of money. Meaning that countries and individuals that have a lot of gold would get much richer, and everyone else would get poorer.Can US dollars be replaced with gold in 2020 for international trade like a country does not have dollars to buy other country's goods?

The Construction Industry: Disruption on the Horizon
The Construction Industry: Disruption on the Horizon
The smart home market is expected to grow into a $53 billion industry by 2022, according to Zion Market Research.If true, that will comprise 3.5% of an estimated $1.5 Trillion construction industry in the United States. It is difficult to say if this will be a sustaining addition to the well established industry, or a new market disruption, as the majority of smart home additions are slow to be absorbed.Given the global escalation in construction costs, there is a desperate need to find efficiencies and make development feasible to match growing housing demand in prime markets. Since the issue is not location specific, but a recurring theme in almost 50 of the worlds most desirable cities, there is a noticeable vacuum in innovative methods and products that can alleviate the astronomical cost burden that has no end in sight.Enter Amazon, the real-world version of the Tyrell Corporation. Amazon has injected $6.7m in Plant Prefab through their Alexa Fund.Why is this important?Prefabricated homes allow the majority of building systems to be pre-assembled off site. Imagine youre building a Lego house, and rather than assembling all the 100 blocks, the blocks come preassembled. It saves a considerable amount of time and coordination, reduces errors, and makes things tremendously more efficient.A University of Utah study reports that modular construction processes result in an average of 16% cost savings and 39% savings in time. When considering a development proforma, these savings are passed directly to the consumer, allowing end units to be rented or sold for considerably less and still maintain a reasonable development yield.What will happen to all the disruption of jobs from the skilled and unskilled labour? We will have to wait and see.Until recently, prefabrication of homes was reserved for more pedestrian housing. With startups like Plant Prefab, were moving into a more advanced, luxury style of prefabrication.Watch for this as for-sale product coming to a city near you·RELATED QUESTIONhow do modular homes hold up over time?For the most part factory built homes, modular, are as good and may be better that site built "stick" homes. Both will last forever if maintained. Being factory built inside a building saves the home from weather damage during construction. The saws and other equipment used to cut and fit the home are better and more accurate in a modular home than a guy cutting a board over a saw hourse in a stick home.

For a web administration interface if you need it, look at webmin.Thanks, RayQuang— — — — — —Market shareUnited StatesSales of Juul increased 700% in 2016. As of October 2018[update], Juul accounts for over 70% of the US e-cigarette market monitored by Nielsen. Juul's market share in the US has increased by 10 percentage points since April 2018. According to Juul Labs, 90% of Juul products are purchased at retail stores as of August 2018[update]. Juul plans to sell their products internationally. According to Dow Jones VentureSource, Juul Labs was the sixth-most valuable US startup in July 2018, behind Uber and Airbnb. Juul's revenue in 2018 was over $1 billion, up from approximately $245 million in 2017. Sales totaled $1.1 billion for the year ending July 2018. Juul's success has inspired a flood of imitators, namely pod-mod devices with similar boxy designs. These devices come from companies ranging from startups to "Big Tobacco" company R.J. Reynolds. The company filed a complaint with the U.S. International Trade Commission (ITC) in early-October 2018 over counterfeit products manufactured by companies in the United States and China that Juul Labs says infringed on its US patents. The complaint seeks to end importation of these products into the US. In February 2019, Juul sued several companies for infringing on its trademarks, among which was a cartoon logo titled the Juul Monster. InternationalIn May 2018, Juul started selling in Israel, which did not regulate e-cigarettes at the time. Israel later banned JUUL in August 2018, citing public health concerns, according to a statement by the Ministry of Health. Prime Minister Benjamin Netanyahu, acting in his capacity as Health Minister, placed a complete ban on Juul because it delivers nearly three times Israel's recommended amount of 20 mg/ml of nicotine. Juul has appealed the ban to Israel's High Court of Justice. In July 2018, Juul announced it would launch in the United Kingdom. Flavours sold in the UK have slightly different names from the American versions and contain 1.7% nicotine, translating to 20 mg/ml, to comply with local regulations. It was noted that the UK was chosen as an early launch market as it had the world's most supportive government when it came to encouraging smokers to vape. In August 2018, Juul introduced its products in Canada, starting with an online launch before introducing them to vape shops, gas stations, and convenience stores in early September. Juul launched in Russia in late-2018 and launched in South Korea and Ireland in May 2019. Juul launched in Ukraine in June 2019. At the beginning of 2019, Juul started selling products containing 1.7% nicotine in Germany. In January 2019, Juul announced plans for a launch in India. In response, the Ministry of Health and Family Welfare called for the device to be banned from India, citing concerns that it could derail the government's anti-tobacco programs. The regulation of e-cigarettes in India is disputed between the government and the judiciary. Six states have banned their use, though the Delhi High Court has stayed the bans. As such, Juul e-cigarettes are not legally available in India and they are commonly sold on the Gray market for as much as $100 for the starter kit that costs $29 in the United States. In June 2019, they announced plans for their products to be available in the Philippine market. On January 25, 2020 it was announced that Grant Winterton, president of Europe, Middle East and Africa, and Ken Bishop, president of Asia-Pacific South divisions, were both leaving the company amid global cost-saving and restructuring. Winterton was reported to organized high-profile, expensive events as part of the companies efforts. Among them was a conference in Berlin last May, attended by 1,500 employees, and a meeting for his direct reports in Cannes, France, in July, according to two employees.— — — — — —Why is it that companies refrain from disclosing their market share?Sometimes, they do not know the size of the market and their market share. nThere are other instances where the estimated marketshare is not public knowledge and may be considered short term competitive advantage or disadvantage— — — — — —Should Apple rethink the iPhone pricing strategy to avoid losing its market share in countries like India?They already are.

Samsung S10 May Use Infinity-o Display
Samsung S10 May Use Infinity-o Display
According to unconfirmed industry reports, Samsung will turn to BOE to produce infinity-o panels on the upcoming Galaxy a8s mobile phone.As we all know, Samsung will launch the flagship of "Galaxy S" series from February to March every year. Recently, the foreign god evleaks revealed that the Samsung S10 may use the "infinity-o" display screen.Infinity-o screen is a new screen design announced by Samsung at the developer conference a while ago. At that time, Samsung announced four new screen designs: infinity-u, infinity-v, infinity-o and new infinity. From the name, we can find the difference between the four screens. The letters "u, V and O" represent the shape of the screen gap respectively.Take infinity-o as an example, there is an "O" notch in the upper left corner of the screen to place the front camera and sensor. Similarly, infinity-u is a "U" gap screen, infinity-v is a "V" gap screen, and new infinity is the goal of future screen development: true and comprehensive screen.It is worth mentioning that the panel may be an LCD panel rather than an OLED as a cost saving measure.It is understood that BOE's current task is to make a 6.39-inch OLED display on Huawei mate 20 pro. As Huawei is unwilling to show weakness and says that it will become the first smartphone with a display hole, foreign media speculate that Huawei's smartphone will also seek BOE to make LCD for it.It is undoubtedly more difficult to produce LCD with holes. It is reported that the camera notch of galaxy a8s display is 6.7mm, and it is speculated that the notch size of Galaxy S10 is 2-3mm.Samsung Galaxy a8s will be equipped with snapdragon 710 chipset, 6GB memory and 3000mAh battery. It is bound to be released in January, but there are rumors that it will be released before the end of this year.
Progress of VVC Coding: the Bit Rate Is Reduced, and the Speed still Needs to Be Improved
Progress of VVC Coding: the Bit Rate Is Reduced, and the Speed still Needs to Be Improved
In the past period of time, the performance of VVC video coding has gradually improved, and the required bit rate has gradually decreased under the condition of the same coding quality. PSNR index is also growing steadily.VVC is the most promising candidate scheme of ITU h.266. It replaces h.265 (we call it hevc), and its goal is to provide at least 30% lower bit rate than hevc under the same coding quality (of course, higher quality under the condition of equal bit rate).First: the running speed is very slow. The latest version takes 50 minutes to encode 60 frames of 1080p video (system specification and data). In fact, I haven't seen any VVC content, so I don't know whether it looks good or the numbers do.We need to establish VVC. You need git, cmake and make.1rm -rf VVCSoftware_ VTM; 2git clone https://vcgit.hhi.fraunhofer.de/jvet/VVCSoftware_ VTM.git; 3cd VVCSoftware_ VTM; 4cmake 。 - DCMAKE_ BUILD_ TYPE=Release; 5make -j; 6cd 。。;VVC also fails to properly process. Y4m input files that contain raw video data and titles that contain resolution, bit depth, frame rate, and such information. We must enter it manually with. Y4m or. YUV.It also needs a configuration file that can fix some use case settings (for example, low latency).1/home/ewouth/VVCSoftware_ VTM/bin/EncoderAppStatic -i Morocco-1000.y4m -b vvc-test-2.vvc -wdt 21920 -hgt 1080 -fr 60 --InputBitDepth=8 --InputChromaFormat=420 -f 60 -c 3VVCSoftware_ VTM/cfg/encoder_ randomaccess_ vtm.cfg;The bit rate has been declining in the past versions. Excellent! (see Y-axis)As a simple indicator of coding quality, PSNR is also growing steadily. There are better metrics, such as vmaf.The encoding speed is...... just so so. VVC vtm-2.0 starts from frame 0.047 by default and has now dropped to frame 0.020.From some historical data, it is very good, but without specific content, these figures are not very attractive, so this is what we will do.nextActually decode and view contentIt is compared with different hevc (x265) and AV1 (AOM, svt-av1) encodersMore statistics (SSIM, vmaf)Test with more sequences and different resolutionsUse more different encoders and speed settings for testingI hope this can be achieved through awcy integration (PR #169), but the use of configuration files complicates things.We will try something new and publish it on R / VVC or doom9.If necessary, compiled files on windows can be provided here.I will constantly update this spreadsheet with new data that may be collected.

If so Yes— — — — — —Hard Drives and Flash Drives with the ps3!?If you have your movies on your PC, you could try streaming them to the PS3. I use TVersity which can stream to my DRV, XBOX360 and Media Lounge. I understand that a PS3 has the same technology.— — — — — —Cable to link two internal hard drives?You do not connect hard drives together, they connect individually to your motherboard. If your motherboard has a free connector slot available, plug your other hard drive up to that. Also, if this is a new hard drive you are installing, you may have to go through the motions to initially install and partition this drive before you can use it. In Windows XP, go to Control Panel > Performance and Maintenence > Administrative Tools > Computer Maintenence > Disk Management > then locate your new drive in the bottom-right of the screen and right-click on it to format the drive (usually NTFS file system). Wait until the format is complete and then reboot your system. Also, do you know if these are SATA or EIDE drives? And did you do as the other users below stated and check the jumper settings on the drives themselves to make sure your main drive is set to MASTER and your second drive is set to SLAVE? Or, simply set both drives to Cable Select. Though, if Belarc is recognizing the drive from within Windows, then I would guess that is not the problem.— — — — — —What are the differences between 2.5" and 3.5” hard disks?As other answerers have indicated, 2.5" and 3.5" refer to the width of the drive platters. Most hard drives fall into these two sizes, and most have similar height and length within the same width category.However, when looking to purchase drives that are of high capacity for their physical size (i. e. : 1 TB for 2. 5" drives), you need to watch out for non-standard drive sizes.For example, the WD3200BPVT is a Western Digital 320 GB internal 2.5" drive. Its height is 9.5 mm, which is about normal for laptop drives. However, the WD10TPVT - a 1 TB internal 2.5" drive - has a height of 12.5 mm, and will not fit in many laptop hard drive bays.If you are shopping for a high-capacity drive to go into a laptop today, you will probably have a hard time finding anything far above 750 GB that will actually fit - let alone any high-speed ones. At this time, the highest-capacity Western Digital drive which runs at 7200 RPM and will fit in most laptops is the 750 GB WD7500BPKT.**Note: I am not a Western Digital employee or advertiser, nor do I intend to portray Western Digital as the best hard drive manufacturer, or the maker of the biggest or fastest drives. I merely have a personal preference for their products, so it is to them that I generally look when shopping for hard drives and checking out current specifications. *TL;DR: Always be sure to check with the hard drive manufacturer, and the manufacturer of whatever device the drive is intended for, to be sure that the new drive's physical dimensions will fit in the space available within your device. Even between drives of the same width (2.5", 3.5", or otherwise), other dimensions may vary.— — — — — —What are some of the best hard drives for iMac?I would go Hitachi or Western Digital (WD)— — — — — —Can a computer have 3 hard drives?yes my brother's has 4— — — — — —Is there RMA for slow hard drives?If it's under warranty, get it replaced.Go to Seagate site, check your warranty status by entering your hard disk model number and serial number. Both are written on hard disk label. You can also see the procedure to get it replaced.Is there RMA for slow hard drives?— — — — — —help installing hard drives on desktop?If it's on an IDE cable by itself set it to master or cable select. If you have to include an optical drive with the HDD make sure the optical drive and HDD are not both set to the same setting. Make one master and one slave.— — — — — —Question about Solid State hard drives (SSD)?Do NOT put your operating system on a solid state drive! SSD's have a limited number of writes. A large number, maybe over 100,000 - I do not know what it is for what you are looking for, but it is a potential problem. Once you reach that number, your computer will start acting strangely, and possibly crashing. Now, if you just want to make a computer for playing games, one game at a time, and you do not care if it breaks down sometime, because you will not have anything valuable on it, then you can give it a try. I do not know if a Mac will boot from a ssd or not, but you can try it and see. Personally, I think that a 10,000 rpm drive like a Raptor is likely to be quite fast, and more reliable.
