Leaf temp for xxxl magnum 1000w mh and hps

I’m running a sun system xxxl magnum with 1000w mh and hps bulbs my ambient room temp away from light is 77f rh away from light is 55% canopy leaf temp is 72-75f hang height from glass to top of tallest plant 40” am I wasting electricity hanging this light that high?

That’s an air cooled reflector, so you should be able to get much closer. Try 17-20 inches away. My HID fixtures run so cool I sometimes let the plants grow right up into them.


I’m seeing twisted leafs already it’s only been on about an hr
