I tested one out that I had in my basement and it fit really well. It seemed to be a good and inexpensive way to retrofit an incandescent hood.

Thanks! If the soft warm bulbs work well, then I'll go that way because they are readily available and cheap! I'll look a bit more for some with a 5000-6700K temp, though.

I have an old aquarium with an incandescent hood. I wanted to use those screw-in spiral compact flourescent bulbs to grow some plants in there. I've heard of people doing it, but I'm having trouble finding any bulbs that have a decent colour range. The only ones I can find are soft white bulbs that say they have a 2700K colour temperature. Not so good for plants. Has anyone found any that have worked well? If so, where did you find them? Thanks!
