PC actinics. If they are 03's like is claimed then they are a violet actinic. As are the phillips and the URI VHO's. They peak at 470nm. not 450. That puts them in the violet range not blue. I want blue. Hence the MH blue bulbs. I don't know how accurate this is but blue is more readily useable by corals than violet or other wavelengths with all the reading I have done. Actinics are violet. Close but no cigar.

I personally like the blue of these bulbs. I currently run 2 55w 10K PC's, 1 OD Marine Glo Actinic and 1 OD Zoomed Coral Sun (which is Violet), the lighting looks awesome and the Corals are doing great :D , damn can't wait to get a cam.
