I was searching for a 3x6 tent and stumbled upon the mammoth gavita tent (3.6x5.9x7 feet) and this got me interested in this new light which the tent was built for. I'm familiar with 600w and 1000w hps but I've never heard of this new gavita Pro 6/750 EL DE flex light. How does this light compare to the 630 cmh? I can't seem to find much on a Google search
