The light it comes with is a 7W 7200K PC. Mine is doing pretty good so far. I feel this color temp light is wonderful for growing coraline. The rock I bought had very little on it and now 3 weeks later I have a good amount growing on my rocks. The before pics are listed in this forum if your interested in seeing them. I'll have newer ones within the week (forgive my photo quality my camera is a POS).
I'll be upgrading pretty soon to a 13w 50/50 (10K/03). With that light on there I feel there will be very little I won't be able to keep in the tank. Certianly no Euphyllia (Torch, Hammer etc...cuz of the sweepers), Clams and delicate SPS.
Currently I have a small colony of zoos (3 polyps) a very bright red/orange mushroom and a small Sinularia (?? 1.25" max). I have plans to add some GSP, more zoos, a small branch of Caulastrea and a small Fungia (if I could fine one small enough). I'm kicking around the possibility of some of the less demanding SPS (perhaps Hydnophora) but more research will be required before trying that
HTH.
