DIY 7,500 Lumens 100W LED Flashlight That Only Costs About $10 To Build
Ready for the latest installment of a DIY lighting project? Assuming you have a couple 18V Nickel Cadmium power tool batteries laying around, as I suspect many of you DIYers do, you can build this powerful flashlight on the cheap. Plus, aside from being inexpensive to build and it’s also surprisingly simple to make.
Take a look at the video to see how it’s done:
While it might not have the look a professional is going for, it certainly gets the job done and could be really handy to have around in pinch. The creator, Julian Ilett, shows us how he assembled a makeshift heatsink to help keep the light cool, but it still gets hot in about 20 seconds. So, if you’re feeling especially inventive, you may want to put a little extra focus on improving the heatsink on your build.
In case you were wondering, he uses a LED light, such as this one found on eBay for $8.99USD including shipping.
