Man, I had 2 1000W lights that I coudlnt run at the same time for mroe than the first half hour of light even with ventilated hoods and 5500 btu's of A/C. You sure you dont mean 68 C instead of F?
4000W is putting out about 15,000 BTU's even if you have cooled hoods. Thats enough to cook anything. |
