Temps when I have the door to the bedroom shut get around 86.2F with AC in house set @ 73. When I leave the bedroom door open, which is close to the thermostat, is around 76-79 depending on temp outside. And yes that lowbay light puts off a lot of heat. Wind speed from the supply side of my fan to the exhaust side is usually around 2.4mph to 4.0mph depending on wherther the bedroom door is open or not, so its circulating a lot of air but temps still do get high!
