What light are you running for your refugium?

I run some 100w clip on "grow" light.

12" 10k fluorescent and 75w grow bulb from walmart. I don't think I need the fluorescent but its good for visual appeal. I don't like how yellow the sump looks with the grow bulb only. My sump chaeto regularly outgrows its 12"X12X14"" space better than the stuff I put in my main display for the mandarin (indirect light under a 14k 250w).

2 36" regular Aquarium bulbs. Simple

I used to have a 65W 6700k compact fluorescent fixture but now I have a clip on screw in type compact fluorescent bulb. As far as growing my macro it works the same in my opinion.

100 watt (I think) CF bulb from HD in one of those clip on things with the reflector. I think the K rating was around 6000. Total cost was maybe $15.
