I'm sure there's more than a few people here who use an incandescent hood with screw-in CFL bulbs for their 10g. I was wondering if any of you have figured how many watts would be considered medium light, and how many high light?

With the size of the tank, and well as the alignment, strength and restrike of screw-in CFL bulbs, using WPG doesn't work well here.

That is a good question which I would like to know as well.
I bought 60 watt bulbs which I guess are really 13 watt bulbs that are daylight 6500K but I have not set up the 10g to try it out yet.

i have a 7 and 10 gal both with 2-26watt day light bulbs and can grow pretty much anything. 52 watts over those should be high.

I've read through that before I started this thread. It was helpful, but I was seeking a more direct answer from people who are using this setup, since the reflectors and splash guard of the incandescent hood would likely cause the light output to be comparatively less than that of the desk lamp that was used in that thread.
