My lights heat up so much that my furnace doesn't run when the lights are on...in the dead of winter. Granted, I have an entire room of lights and the thermostat is in the grow space...but the heat from lights keep the room around 72-74 during the winter. Until it gets really cold outside I usually keep a couple of windows cracked so the room doesn't get too hot.

MY HOT5s are much warmer than the T8s in the phal area.

Yes, but do your T8's give off the same amount of light as the T5's? Measure and find out.
