I was wondering if CFL bulbs had a burn in time like MH. I figured not, but it doesn't hurt to ask.

Tell me about it!!! The JBJ bulbs were just white. You couldn't see any blue in the bulbs. Now with the 420 bulb you can see lots of color. With any luck some of my corals may even flouresce (sp?). I am happy with the choice of bulbs.

BTW, have you ever seen a 14000K CFL bulb, lol?
