Decent LED for my tent? I have the OG Stacker tent (39.75"x39.75"x60") and was wondering what my best flowering options are.

My buddy says that my best bet for this tent would be LED for heat control and other reasons. The only issue is that my budget is 300$.  Is there even an LED that would be fine for this size? The ones I'm seeing are pretty pricey. Thanks for the help!
