I'm wanting to get a 65 gallon tank and was curious about lighting it. I was rather startled by the high prices of aquarium light hoods. Then, when looking at florescent lights on google products, I stumbled across these fluorescent flood lights.

OK, i'd like to give my aquarium a little more than 2 wpg so lets say 150 watts. I've read that the average fluorescent light produces between 50 and 100 lumens per watt. So 150 watts would be up to 15,000 lumens. These flood lights apparently output 6,885 lumens or about 7,000. Another way of writing this is
(65g*2w/g)*(100L/g)/6,885= about 2 Lights. My question is would having 2 of these flood lights about 2 ft above my 65 gallon freshwater planted aquarium be sufficient lighting or would it blind the fish.Thanks in advance. If this is OK it would make a much more affordable alternative to the standard florescent strips.

Watts per gallon is a horrible way to measure light its not accurate it all. Watts is a measurement of power not light. I wouldnt use that, it might be strong enough but it will probably spotlight and just have bad wavelengths (color temp) for growing stuff. In fact, now that I take another look, the spotlighting effect will be horrible that things reflectors are made out of poop. Before I go further I would say its pretty much an all around no-no.

It would be nice if you could get something that would work well for that price though.
