Build A 100W LED Flashlight

Build A 100W LED Flashlight

In case you’re not aware, you can hop on your favorite online Chinese electronics retailer and buy a hundred Watt LED module for less than $10 USD. That’s an enormous amount of retina-burning fun, but how do you turn it into a flashlight? DIY Perks shows you how . The main issue when dealing with these large LED modules is heat. Even though there’s many times more efficient than incandescent bulbs per Watt, that’s still an incredible amount of heat that needs to be removed. There’s a piece of equipment you might have sitting around that does just that: the lowly CPU cooler. If the CPU heatsink and fan are big enough, the LED module can be attached right to the bottom.
