Can aquarium lights be too bright?

Im using white compact fluorescent in a 10 gallon tank. Its not made for aquariums however. Its a 60 watt equivalent to a incandescent light.
Two 800 lumen bulbs. I know about heat output problems but are there light intensity output problems?

that light is no problem…

the only effect may be more excessive evaporation…

I had a planted 10 gallon with 2 X 36 watt GE spirals for a total of 3200 lumens and it was fine.

good luck

    The light output on regular florescent lights are even close to the output on aquarium florescent light bulbs which are made for aquariums have a color spectrum for fish and aquatic life.

    yes 60 watts over 10 gallons is very high light (6wpg) of course the wpg rule allmost unaplicable for smaller tanks, if you are going to grow plants in this tank i would do lots of reading on co2 concentrations, distribution, flow around the tank and a fert dosing regime. if not then you are asking for algae.

    i do not know the reason why you are using that light. im sure it will produce allot more heat on the surface and making the water warm. yes these lights could be the problems even if you are trying to grow plants. under this very high lights you will need to use co2 to prevent algae.
