Interesting. I like the idea of having heat sink fins versus a fan. My main reason for going with LEDs versus brighter halogens was for power savings - my LEDs are rated at 30W vs those ones at 40W. Anything to facilitate a longer ability to EOC at night.
Unfortunately the exact bulb I used was discontinued except as a yellow fog light (the 6000K/6500K variant is no longer available) but appear to have been replaced with a newer model.
