Don't forget T-5's. They rival and possibly exceed the intensity of PC
are different names for the same thing. What I have noticed is that, typically, the bulbs we use for aquariums are called PC
's and the screw in types that are meant to replace incandescent bulbs are referred to as CF
's. I'm sure this doesn't apply in every case. I have seen the aquarium bulbs referred to as CF
on several occasions. Here is another fixture you might want to look into. It is a little more expensive when compared to the sale price at Hello Lights, but it has moonlight.
You should be able to keep soft (most) corals and get good coraline growth with these lights. It won't be enough for SPS
or anemones though.
