That damn light gets hot, it was like 90 in there.. I have two 22 inch box fans in there I turned the one that is blowing the hot air OUT from the ballast on high and it got down to 84 with the window open in that bed room... The other fan is blowing between the canopy and the light.. but I couldnt turn it on too high, because it looked like it was a hurricane in there... and I thought it might damage the plants.. As they get bigger... they might be able to handle it..but not now..
