They say something like "it uses 65 watts, but has output of 500W". So the first thing I thought was it was too good to be true, and that it just had more lumens so it appears bright to the human eye. but I read through it and it says 6500k, and "phototropic lumens". maybe it just has a lot of reflection?

it says "blue rich light". but 6500k is more yellowish.

$25 for 65 watts is still pretty good though. I might get one for my 20 gallon tank.

what do you guys think?

edit: ok, it says "white daylight 6500k" white light meaning it has all parts of the spectrum, but the color averages out to be more yellowish around 6500k? is that any good? it must have a lot of the green phosphors to make it look so bright, but doesnt help plants.
