I trying to grow in my hot garage. I got a 5000 btu air conditioner coming in the bottom intake (4”) a 8” oscillating fan in the middle , a pB200 light and the transformer on top is rocket hot. To the point it’s hard to keep it cool in a 2x3 plywood cabinet. I also have a 4” outtake fan on top so good airflow. But hard to keep cool.

Any one know of a good solid light that runs cooler?
Almost ready to put my t-5 Florissant light in.
