Club 315w lec

The double ended 630w cmh will put out a TON of heat. The double ended 315w cmh will be much more manageable in terms of heat.
heat is determined by how many watts are used, 630 cmh puts out 630 watts of heat, approx 2150 BTU of heat for 630watts.

can anyone tell me how much heat the lec gives off, say compared to air cooled 600w hps? also will a 315 lec, maximize a 4x4 space? or could it be better?

I run a sunsystem lec 630. It stays pretty cool. It does put out some heat but very little compared to what I'm used to with 1k hps. Each 630 will cover a 5x5 area, same as a 1k. I plan to run 2 over a 5x10 scrog. A buddy of mine runs 2 in a 4x8 tent.

I have 2- 6" passive intakes, and a 8" - 780 CFM exhaust w/ speed control on a charcoal filter. Those numbers I gave you is when every thing is turned off.
Yes I sort of figured you must of run the lamps without any ventilation. Never did that to check the heat difference.
I have passive intake and a 6" exhaust w/ speed control and charcoal filter. Also have A/C in room where air is drawn from.
Run the exhaust on low and the speed control between 1 and 4, depending on outside temps, when not using A/C I can draw air from the outside, which is what I do in the winter. The temps in the tent during 12/12 with lights on is 79 to 84 and lights out 68 to 70.
Never allow my temps to exceed 87.

Thanks. Guessing 3-3.5lbs for final under two 630cmh
We will find out here in a couple of weeks
The lec work better than i imagined. I have 2 mainlined sensi super skunks just starting week 4 under a 315. Its the first grow with it and i am quite happy.
so 2 wouldn't cover a 4x8 as well as 2 600w hps?

thanks I appreciate it
Yes sir they will. And u get all that lovely uv for tricomes. 2 315s is comparable to 1000 but with better spectrum and more uv.

So the guy asked if 2 lec and a 600 watt hps would work. Yes it will. He didnt ask about 3 lecs. Read the post. I am out of here. Nothing constructive going on here. Good luck.
