100 Watt LED Version 2

This second one has a larger capacity, higher voltage Lipo pack...
(Equals longer run time between charges)






Build pictures and video below:




















Battery:

6S 12 Amp hour Lipo pack!









Battery voltage monitor color code:

Bright blue - Full charge
Cyan - Very good
Green - Good
Yellow/Amber - Low warning
Red - Batteries low







Voltage and current readings:

To the emitter - 33.2 Volts / 3 Amps

Battery current draw - 4.07 Amps

This will be about 3 hours run time between charges...

Total weight with battery and everything - 7 pounds, 8 ounces. (2 pounds lighter than my 100 Watt HID build)






Here's a brief video:

Need a balance charger for the Li-Ion battery pack:
Here's mine



The aluminum frame is made from 3/4" X 1/16" angle - Home Depot

Handle is 3/4" X 3/4" aluminum square - Home Depot

Front stand is 3/4" X 1/8" aluminum flat - Home Depot

It's a fun project, quite a bit of work though. But nice payoff!

Looks great Jayrob. I just got my parts in from China to start playing with. I ordered 2-100 watt LEDS, 2-5a/30v drivers and one 110volt driver with heatsink/fan combo and lens. Just playing with the LED on the heatsink/fan and my bench power supply is amazing. I ran it @ 3.5 amps and 30 volts for about 2 minutes and the LED was 174 deg. F. Do you know at what temp is safe for the LED?

Thanks

I'll be following this one as I'm currently building one myself.

WOW, that's really cool. Reminds me of a home built light I made when I was 12 years old. I used a similar sized metal box with a handle on top and mounted a fan in the back. Inside I installed an over head projector bulb that I stole from school. It was really bright, but had a cord so it was only good for messing around in the yard.
