DIY Multi-purpose Light Build Uses: Work light, aquarium light, plant grow light, UV light, and more... I've built several of these lights and they're amazing! They're incredibly useful and super easy to build using old parts you probably have lying around. I've been using them as work lights, aquarium lights, plant grow lights, and even for some fun UV light projects. The goal is to create a very cheap and easy-to-build design. The housing fits snugly around an 80mm x 80mm CPU fan, and it accepts heat sinks of various sizes or small pieces of metal sheeting to cool the LEDs. I've had great success using leftover 12V power supplies from old routers. The fan is connected directly to the power supply, while the LEDs are wired in series. I highly recommend using an LM317 to control current to the LEDs, but you can get away with just a resistor and connecting the LED directly to it - check Wikipedia for more info. Since this setup is well-cooled, my lights have lasted thousands of hours without any failures so far. I suggest using thermal adhesive to attach the LEDs to the heat sink and caulk or epoxy to secure the heat sink to the light housing.
