If so, you will definitely like having an LED work light! It is shock proof, cool to the touch, never needs bulb replacements, and uses just 100W of energy while delivering the same light output as a 500W halogen bulb!
a.) 100W LED module. I'd recommend a "warm white" with a color temperature of around 3300k. It will be much less "yellow" than a halogen bulb.
b.) 100W LED current limited power supply.
c.) Heatsink for the LED. I picked a surplus CPU heatsink from a Dell PowerEdge 2950 server. This heatsink was designed to cool a quad-core 3.0GHz Xeon processor with a maximum 150W TPD, so it will be more than enough for a 100W LED with 80W-85W TPD.
d.) Pair of fans for active cooling. I picked a pair of salvaged 12V 40mm x 40mm x 28mm server fans, which draw 0.15 amps each @ 5V. And since the fans are running at less than half of their design voltage of 12V, they are barely audible when powered from a 5V source.
e.) Donor halogen 500W work light.
f.) Power supply to provide 5V for the fans. Most old cell phone chargers will work. They usually provide 5V @ 1 amp.
g.) Some nuts, bolts, and scrap aluminum.
The pictures explain how the whole assembly process looks. Using some small nuts and bolts the LED is affixed to the heatsink, then a custom bracket is made to hold the fans in position.
Wire everything up. Don't forget "ground" for safety. Fits perfectly!
Now you have a cool running work light with the same light output as a 500W halogen bulb. Same dimensions, just as durable and lightweight. The LED runs at around 50 centigrade, so it should last much longer than the rated 40,000 hours @ 65C.
