| Video Discription | This video (very roughly) outlines how I built a 5400lm grid-powered LED ceiling light for about $45. The efficacy of the entire system, from the plug, is about 60lm/W, which is roughly equal to that of a compact fluorescent light. The efficacy could potentially be increased quite a bit by not using two laptop power adapters to supply the 38 V bus that the constant current LED drivers run off of.
