I currently have about 10 T8 flouresent tubes on my system of various kalvin ranging from 20000k to 10000k. In addition I have a energy saver twin spotlight of about 23w (energy saver speak). I was thinking of replacing the energy saver spot and 2 T8 tubes with 2 or 3 150w metal halide pendents. Would this be and improvement given that the MH wattage is basically the same as the energy saver and T8 i will be removing. This may be a silly question since i'm sure that MH is always better than energy saver, but before I spend mega $$$ what do you guys think.
