The headlamps I am using take a P45T bulb, and I have a pair of hi-power halogen bulbs, but I was wondering if anyone on the forum has tried LED replacements, and what their impression/experience was.
I have a couple of Stinger flashlights with the LED conversion and they are seriously bright with really good battery life so the next obvious idea was to search for a replacement for the headlamps on my car.
They are available, not too pricey, but it seems they are not as powerful as I imagined even using the "Equivalent" charts.
The wattage on the LED bulbs seems to run about 20% of a tungsten lamp, and the measure I am seeing used for brightness mostly is lumens, but one or two vendors used temperature in Kelvin but I suspect this is the color of the light emitted.
The most powerful lamp I can find Fits a BMW, and it seems that the limiting factor is not bulb heat, but heat behind the lamp caused by the junction....some even talked of a fan to cool the base.
Any experience on this out there?
Cheers
Phil
