I think there is no argument that lights other than the one I got are what you want for commercial growing. I'm not commercial, so this will be an interesting experiment. The lamps I got have, if I may be pardoned the pun, glowing reviews, which are in sharp contrast to the opinions rendered here, which is interesting.
All the more powerful options come with tradeoffs. Heat, power, cost. I don't need huge yield; I will be happy with .5g per watt (250 watts at the wall). I do want quality, and am thoughtful about whether that will be achieved. Time will tell, the experiment is underway.
