I would not waste my time on a DIY Led
system by the time you buy all the supplies you need you just paid for a really nice led
light system already made. If you have really deep pockets the Ecotech Radions are ally nice lights but I myself cannot afford those so I myself have been looking at the AI "Aqua Illumination"hydra lights to replace the old led
lights that I have over my tank which are no longer can't remember the name brand but i got them off of Amazon. Their was a thread on here about those lights on Amazon and Ebay very reasonable prices too just not name brands.
