Has anyone been trying LEDs on their tanks? I saw one lamp at Home Depot that looked bright enough for a small tank, but really no data was available and the human eye is a poor guide on this. There are also these: http://www.earthled.com/zetalux-led-light-bulb.html
Seven watts producing the equivalent of 50 watts if I read right. The drawback is four bulbs for $179. I still have one similar shaped but different technology three watt bulb that produces about 50 watts of light, but after buying one for under $10 a couple years ago, I have never seen them again. It looks like a twist bulb inside a globe, but the tubing is about the diameter of spaghetti.
