I would $8 per bulb and i you uy both then free shipping. Perfect for and incdescent or diy hood over a small tank and would give 4 watts per gallon for a 10 gallon.

Incorrect. Due to restrike, 2 20W bulbs is equivalent to approx. 1.5w/g-1.75w/g. Never go by the w/g rule on 10G tanks, especially with screw-in CF's. I'm running them, so I have a pretty good idea on the lighting, and that's where I would rate them. And for other reference, if anyone get's the 25W bulbs, it's equiv. to about 2.25w/g. I'm running those too. ;)
