CocoSativas - I don't disagree with what you're saying about lighting and bulbs. I'm just not convinced of the difference and therefore the justification of the cost. I've run cheap and expensive lamps on good digital ballasts and have seen great results from beginning to end with both. When you factor in lumen depreciation and lamp replacement, the cost can get up there depending on the size of the growroom.
You are right about the new lighting technology. I've used one of the 315w CMH lamps and they have great color. I also have one of the Area 51 XGS-190's and it's a beast for a 2x3 ft area. I really want to try out one of the new lights with the white COB leds. From what I've seen online they look like real gamechangers.
This comparison grow results video is a good one too for anyone interested:
