2 cents:
I think Gavitas really require a room where height is not a concern. Most rooms I have been in do not qualify, or have poor result from low ceiling double-enders. I've been running mine at a minimum of 36" from the top on the 1150 settings. The manufacturer suggests 40", but I keep the tallest tops right in that range. I see some ppl trying to run this in lower ceilings with like 12-18" and it does not work. You get foxtailing, bleaching, burning, ugh....
For ppl with lower ceilings, I've been seeing some great results from teh 370w CMH's this past year, some ppl dont even run a/c with a couple of them and good ventilation.
Point: Where Doc is a sort of tester guy, I don't think that the LED and Gavita are in the same consideration when u are planning a build. One will fit your situation much better than the other, I should think. If you have height and a good a/c, the Gavita's a no brainer.
Great customer support and the equipment is gorgeous.
dang i think u owe me like 45c change or something...
