I get mine at Revy/Rona/whoever they are this week.
I have always used them in conjunction with GE Sunshine bulbs (the Chroma 50s).
Plants typically did quite well, though the light-loving plants of course didn't thrive with the light output, but I was able to grow anubias, wisteria, crypts, lotus lilies, nomaphilia, etc..
One thing I wasn't wild about was the visible colour - it just looked a bit too yellowy for me (could have been the Chromas), but the results on the tank were good.
If it's between those or some $50000 aquarium store bulbs, do the no-name ones. I think T12 NO gives you pretty consistent results, and the more I read, the less convinced I am that plants are terribly picky about Kelvin ratings.
