In addition you need a reflector because half the light is pointed up....and you get the drift, stick with screw in PC's. Over a 10 gallon I would do a bulb like this:

or one of the ones similar to this that are a flood light because you will have little heat and wont need a reflector. Just check the spectrum on the bulb to make sure it is a daylight spectrum.[/QUOTE]
Yeah, that was what I was (erroneously) calling a fluorescent.
[QUOTE=]I'm sort of using my 20G upstairs as an "experimental" tank. I bought a cheap $60 PC light off EBAY, and that's all I have up there. It has 1 daylight and 1 50/50 bulb, for a total of 130W. I've learned:
some zoas really multiply better under the lower light.
the red/purple, plain mushrooms multiply faster under the PCs than under T-5s.
digi frags grow like crazy under pcs, but they are all brown.
my plate coral LOVES the PC light much better than the t-5s.
hairy mushrooms stretch out farther than under t-5s, but are skinnier, flatter, and not as pretty or as hairy as they are under the t-5s.
elongated xenia doesn't seem to notice the difference between pcs and t-5s and is about to get completely ripped out of my tank and given a burial at sea......[/QUOTE]Your comparison of T-5's and PCs is interesting, but I would think if wattage and kelvin are the same, the difference is negligible? Or is it? I'm running a 250W 20,000K MH and 2 65W Actinic PC's. I have mostly an interest in LPS (including a plate) and have wondered if I should just stop running the MH completely and work with the 2 PCs. I have all my LPS near the bottom and to either side of the light, but I obviously would like to optimize the environment.
