Default 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

What is more important is the CRI. 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.

I've seen folks here say over and over that plants can grow on just
about any light but green. 5500K is a very nice color temperature for
freshwater - it's what I happen to be using right now and plants are
growing fine.
