Coleman 2-AA Luxeon Mod

[bikeNomad]

Well, I re-designed my LT1308B booster board to fit inside this aluminum flashlight.

It actually ended up quite nice, and the thick brass plate screwed into the aluminum body does a very good job of heatsinking!

Advantages are:
<UL TYPE=SQUARE><LI> Constant current design gives constant brightness for entire lifetime of batteries (down to 0.46V/cell) without overdriving Luxeon
<LI> Luxeon mounting gives good heatsinking to case of flashlight, so no overheating
<LI> Easy mods to flashlight mechanically: drill/tap 2 4-40 screw holes, one more hole (in brass), trim end of reflector
<LI> Parts run about $10-$12 (need to make up a parts list)
[/list]
Details and pictures are here on my web site, but would one of you with a mod site like to grab these? I really don't want the traffic on my home server...

OK, can you make me one of these? I made a mod with this flashlight and a regulating circuit, but it's not nearly as nicely done! I can even send you the Coleman flashlight to do this...
Please????

Thanks for posting your work. I'm also working on this circuit. Hey, why reinvent the wheel. I will use your circuit design. I have the same flashlight, and I'll do the same modification with mine.

Thanks,

bikeNomad,

I can post your page on my web site. I made a copy of the page, and when I get around to it, I'll modify the HTML and it'll be up.
