MH Bulb Decision Requires Lighting Gurus

[dirtyreefer]

I have heard almost nothing but good things about XM 10K SE bulbs. They are a very crisp white, and make ushios look like iwasakis.

Although I'm not sure on coloration, I am pretty sure that a higher PAR will yield growth in your corals (especially SPS). I would choose that supplemented with actinics because a 20K bulb loses it's PAR alot more quickly than a 10K.

Anyone can correct me if I'm wrong, but this is my research.
