From my personal experience I had 4 Blackstar 600's actual 340w each in my flower room 7x15. I run a passive air room pulling in fresh air through a furnace filter fitted into the wall via a 8" 745CFM fan with large carbon filter. My temps then were 81-85f lights on. I ended up selling the lights 3 of them to a friend and I kept one for my veg room. I replace them with 2 1000w HPS digital baddass ballast and bulbs in 8" blockbuster hoods. (carbon scrubber - hood-hood-fan-exit). My system consistantly runs 74-77f lights on, during winter monthes I can keep it at 68-70 if I run the fan wide open. That;s just my personal experience with led and hps and the results I got. I thought for sure I was going to have to add A/C the the HPS set up.
Its probably because leds just through the heat everywhere. Your hps hoods direct the heat out. Very good info as well +rep
