How 'bout these fluorescents?
I have a bunch of these lights left over from a work project:
http://www.durotest.com/fluor.vitalite.html Actually the ones I have might be different but made to the same specs. I have to check the box. Anyway, it says that they simulate daylight with a temp at 5500K. How does this jive with lighting conditions for aquariums (growing plants, that is)? I know it is complicated, but I see a lot of people talking about 6500K and so on. Are "daylight" bulbs not the right thing for a tank? thanks, dwhite |

These lamps have a CRI of 91, which is pretty good - you'll find a lot of plant specialist lights don't even have as good a CRI. I'd say from my experience these lights will be quite good for plants.

OK, thanks Oz and Elaine. That's good news!
