Well, it's DIY, so technically it came from my basement.Where did. You get that setup at
The parts came from a number of places. I'm new here and am not up to speed on the rules about naming vendors, so I'll just say that the LEDs came from a well known LED website, the drivers came from an electronics parts place, the power supply was found on the auction site and the remaining parts were sourced locally. The 41"x3.5" heatsinks were not originally meant to be heatsinks, they were aluminum extrusions that we're "repurposed."
