Next up was working on my LED lighting. I am still waiting on my Cree emitters to arrive but I had some cheapo chinese white emitters so they will do temporarily. I'll build a second array and swap in the mix of blue and white Crees when they arrive. Here are the various parts and the little parts box heatsink I drilled and tapped:
And the completed array powered up:
And finally the tank filled with water, sand and some rock (which has been in my frag tank and was in my 10 gallon nano before that):
I will endeavor to keep the updates more frequent and regular from now on.
