You should have some ventilation if you can. The light is hot but not too much
Super lemon skunk, grew it in 2014, good plant. I imagine the haze is also.
I recently purchased a mars hydro tsl2000 and it was longer in length than I thought and way hotter than I expected. the diode side was also, hot, hot as hell. it looks like yours, metal reflector, but longer... i boxed it back up and returned it. I wonder if we have a different understanding of heat or the tsl2000 is just different than yours
I got a bestva pro 2000 which has changed my grow 10 fold and has very little heat... but i guess what's hot and what isn't is different for different people. That Mars Hydro felt like I was dealing with 1000w HPS equipment lol
