Based on the TS line and what other parameters? He didn't even state a specific light in the TS series - they range from something like 100 W to 450 W, if memory serves. Granted light is very important, but yield is based on so many more things than just light. It's like asking what's the average yield of a certain nutrient line. Don't go by MH's yield numbers in their marketing material either. I think it is totally idiotic for them to even state that metric. They are just setting themselves up for a lot of disappointed customers.
My point is don't get caught up in all the marketing hype.
No mars light is no good there crap, check out hydro crunch, viperspecta reflector series 2 cycle, around same price but better, i recommend California light works, or if you have serious cake check out black dog, i bought a 400w full spec mars hydro light could not grow a dandylion, paid $180 and sold on e bay for 35 bucks and glad to get it, Mars lights suck dont get scammed, this is my personal opion from experience and i have allot.
