# 40 watts.
# 2775 lumens.
# 6500 Kelvin
From what im getting on the Lighting 101 it sounds like it Should be ok.
But I have a bit of a problem. I have a 29 gallon tank. And theirs probably A good 6-7 Inch hang off on each side. But I have a BUNCH of lights 4 twin tube strips. 8 bulbs in all. Suggestions on what I should do? The Tank is 18 inches deep too, going to be harder to get the plants up close with out a bunch of Space. Do you think the light bulbs will be strong enough?
