Maybe it's an american thing...

Everywhere online says 4-6 watts per gallon, 2-3 watts per gallon minimum, geez...

I hope no one tells my plants that...

I guess so, I got rid of all the tube bulbs and bought a CFL. It was pretty expensive but saves alot of energy over time. Its bright enough to light my whole room lol! Its some sort of energy saving thing, its written on the back 17watt and bright as 75watt so its pretty cool.
My hood has some gaps so I'll be setting up some reflectors soon.

You have to ignore the "75W" on the back- that's compared to incandescents which are useless. You basically have a 17W flourescent light now.

Is it 6500k "Daylight" or "Cool white"?

BTW, that pink bulb would have worked. I'm willing to bet it was a "plant grow light", which works well as a supplement to a 6500k bulb. (If you decided to have two...)

Daylight 6500k. I didnt like the pink one cause it makes my tank look odd.

Yea, they're not good as the solo light source for that reason.
