I get to play with this stuff a lot more at work now. I just got named as our north american LED techincal expert for my company.
Buck, boost, same difference :tonka: (sorry, I'm tired!)

I understand that you guys want to save money at the cost of more power wasted, but I build more for efficiency.

I want to have rock lights that are as bright as the incandescents that I can leave on for several hours without frying my battery (in case I need to crawl under the jeep and do some work or something of that nature).

Again, though, you're losing out on some functionality. My set-up allows me the option of a PWM brightness control, or a DC signal voltage level to control brightness (and, of course, there are more advantages to this), which is flippin' convenient.

Congrats on your promotion.

I don't deal with LEDs too much. I've only recently picked up an interest with them when I was assigned to a project where I use infrared LEDs and infrared receivers to communicate and build a virtual 3D grid in free space (they can also communicate several other things, but that is the neatest part).

Kinda' cool stuff!
