I've got 2-55W 6700 PC's on my 55G planted FW tank, and that is plenty of
light. With CO2 the plants grow out of the tank faster than I can prune
them. Can't imagine needing more light than that, and sometimes I think
I've got too much light. Some fish don't like so much light.

Would four T5 6500K 54 watts bulbs place 12" over a tank be too powerfull
for a planted tank?

I use 3 55 watts PC bulbs 3" off the surface with good effects. I doo get
thread like algae over the third light occasionally but is very simple to
control really.

Thanks
