I picked up one of these at MACNA:
BlueLine 24" 18w Blue VHO LED Strip :: BlueLine VHO LED Strips :: LED Lighting Systems :: Lighting :: Champion Lighting & Supply
The only real disappointment with my all in one tank is the inability to select only SOME of the lights in the fixture. It's all six (T5s) or none. So I figured I could rig this up somehow. Turns out that adding this in was easy peasy. I'll add a pic soon.
Now, I have two big concerns...
1. What kind of heat rise might I expect? I am at about 80F in summer days without heaters running.
2. To mitigate heat, I was thinking of splitting the light cycle of the LEDs. Few hours in the morning, and then a few hours in the evening. With both cycles overlapping with the T5s for half of the time. Any reason to worry about that kind of intermittent lighting for the animals in the tank?
By the way, the added color is awesome!
