I used a heat shield for my mag xxl reflector. I used mine for two grows sold it then bought a 12" inline fan. It kept my tent about 3-6 degrees cooler. Which is good but I was looking for 10 degree drop minimum. Evacuation from the bulb has def helped me out the most.

I think if I had everything else sorted out, this would be my last buy.
