I have been thinking about how much a LED light for a 10 gallon tank would cost. So, I think I will make that a project for today - not making one, but trying to design a minimalist one. I do have an empty 10 gallon tank, but, please, please, I hope this doesn't get me back to two operating tanks again!

EDIT: It looks like I could make a 10 gallon LED fixture, giving moderate lighting intensity, using 16 Cree LEDs, for about $125 total, making good use of surplus materials. Not cheap for a 10 gallon tank, but the need for DC power, a heat sink, cooling fans, etc. makes it almost impossible to build one cheaper than $100, no matter how ingenious you are. You have to look at this as half entertainment and education, and half getting a nice light fixture.
