not much knowing about the cmh types, but LED is the way to go in the lower wattage region.
Regular Lamps need to be big to be effective, Leds dont, their efficency isnt bound to a minum size.
simply compare what a 100w anda 315w chm put out per watt and do the math.

so thats 110 lumen per watt for the 100W CMH if i see it right.
My CXB3590 Cob should be more in the 170 lumen per watt region at 50W max each (but would need to check the exact numbers again)

Beside that the more light sources you have the better the spread, therefore less light loss will be.

sounds good to me, but everyone if after something else, i am after a good lumen per watt ratio as i pay a lot for elctricity.

Right now I run 13x 1,000 watts HPS. Think alternating each light with COB over time. Each light covers 4x5ft area. I am yield type of person. But also product quality at the same time. Requirements to pull 16 oz per light is a requirement.
