Bulb replacement choices

[TANGOMAN]

Aaaah, I was afraid someone would ask what type of corals I want to keep. Unfortunately, I know more about lighting than I do about corals. Currently I have a pipe organ coral that did awesome once I increased daylight bulbs in exchange for actinic. That coral I'm presuming was beyond what I should have began with but it's doin' good. I have some "button polyps" (?),dandilions,er, mushrooms.(damn weeds), and one other coral, I don't know what it is ops: , small yellow polyps that are spreading nicely. Stop laughin' at me !
I'm interested in "leather corals" (?) in the future. MH isn't really an option right now. $$$ and low profile (4") canopy.
