Is an 120V LED Light Bulb Compatible with a 220V Mains? [closed]

Unfortunately, as far as I can see in the linked pages, Cree does not specify the allowed input voltages. Unless you can find markings on the light or its packaging indicating that it will function on 240V as well as 120V, I have to assume that it was designed for 120V only. In that case, plugging it directly into European mains voltage may well destroy the electronics in the bulb and possibly even cause a fire. The only known safe way to use this in Europe would be with a step-down transformer

The typical car alarm light is red. Make sure it is in a noticeable place and bright enough to make any burglar think twice before he messes with your car. Another thing though is to hide anything of value under the seats or under blankets. Store your car in your garage if possible and dont make the car a tempting target overall.

It could be a defective unit have you checked the actual current useage. If you do not have an ammeter--use a 1 ohm 10W resistor it can handle up to 3 amps.( or 360Watts) E = IxR If R = 1 the E = I volts = amps.
