I am looking at putting in a light refit with 3 250 14k MH, and I am torn on whether to go PC actinic or VHO... my current tank has 3 175s and 2 96 watt pc actinics... the wattage im reading on the 72 inch vho says they put out 160 watts and it would hold 2, so thats much better than 2 96 watt pcs, but I dont have any experiance with the VHO bulbs... any input on the best choice will be appreciated... :blink
