What about the heat? In veg I go bare then in flower I'm trying to lower the heat! I tested out both hood/tube in my workshop for 15 mins each the tube had the best looking and even lighting with the biggest footprint with pushing the air was the coolest but the light still gets pretty hot right in the middle of the light where's it's the hottest but you can still touch it. but you can feel the heat!

Clearly, but these products exist because we cant all run bare bulbs for valid reasons. Besides you can get your hood closer to canopy when air cooled negating the losses.

I went with the cooltube with the air being pulled out it works great 1000 watts cool to the touch ! It's totally works different in the tent with the tubing connected than in my workshop. First DAY OF FLOWER TOO I was waiting till I went to flower Every with the 40 pint dehumidifier blowing hot dry air the intake air today is 50* F
