I think you find that most of the die-hard LPS keepers, prefer VHO lighting. Gives the best color and good growth with out any heat associated problems like halides. I am running 300w VHO on my 37 Oceanic cube(ish) tank. 24" x 4 bulb. 2 URI SuperActinicR and 2 URI 50/50 atinic white. Probably the most common bulb config for LPS. I am really happy with the results. Great color with URI bulbs, and happy, growing LPS. My frogspawn,hammer and torch are doing well under VHO......as well as leathers, GSP, zoo's and shrooms. I am not into SPS. I think VHO's are the best bang for the buck. I would highly recommend hellolights if you are looking to purchase a new system. Great prices and cust service.
