A brief update......
Several new e-tailers selling/making fixtures with improvements in both color and control. I am considering a sidestreet brand to just try out on the frag tank. I am also considering a small kit for my upstream fuge.
I still mainly hear about smaller elec bills, less heat and more control when people talk about LED's. I am waiting for them to be described as looking better than MH. The fixtures i've seen simply do not. IMO
