I have been looking at using 20w 14000k LED Floodlights for my new 100 gallon. I can get them for about $50 a piece on ebay. I have done some research online and found some people that have done this but would like to know if anyone local has tried them. Here is the link for the ones I am looking at: http://www.ebay.com/itm/20W-16000K-1400LM-LED-Floodlight-Aquarium-/220906424121
