Cree Dive HeadLamp Attempt #2

[BikerManiac]

My second attempt in modifying a headlamp with new Cree Emitters. My first attempt resulting in partial failure. More like complete failure... but I guess I have learned from my previous mistakes and have started trying to do it again.

Parts
1 x Pelican 2600 Headlamp
3 x Cree Emitters (I have 2 x P4 emitters and 1xQ5 Emitter)
3 x Cree Reflector.
3 x 800mA drivers

Right now I am missing a round heatsink. I have been looking for it and have not been able to find one that will fit and fit my purpose. It seems the only way to get one is to get someone with a lathe to create one for me. If anybody have access to a lathe, please let me know.

I am basically looking for a 47mm aluminum or copper in diameter round disc and 20mm in height.

Without a heatsink the leds will not last 10 minutes at 800mA. I have been thinking even using 500mA to keep it cooler. But that will not get me 200+ lumens which is my primary goal.

I will post more information and pictures once I find all the parts and start soldering the leds.

Finally was able to finished the project thanks to some great help from ST forum guys.

Impressive. Did you manufacture the reflectors?

Also, in the last pic, what's the comparison light?

Your light looks brite,my old style seems to diffuse as I see your trying something else but,,

Did you see the units with the LEDs in a pre made package 12V white light?I used a set in a pvc 1-1/2 coupling with a 1/4" plexi lens for a UW video camera good-but that's two year old led tec now I see some real white brite lights soon to hit the market!
Dam wish I would of bought a few more grand of CREE last year at $15 a share led is is the future!
