Hi there, I've been wondering if 2 of these lights: 250W XM 10,000K (http://www.hellolights.com/250wxm10000k.html) would bu sufficient for my 166Gal tank to grow plants? Or maybe 4 of these: XM 20,000K (http://www.hellolights.com/175wxm20000k.html)?

Please let me know.

Thanx
RL

I don't think they will. Not flourecent. That's a big price tag for a light bulb!

They will be fine. 2 watts per gallon is a good target. 4 watts per gallon is your upper range or you will have too much algae growth.

have fun,
Luca.
