Always reliable, they do great every time.

Growers choice always does amazing

Love growers choice , lights been running strong for a couple years now.

Love the growers choice lights. I can keep the light 6 inches away from my plant in flower.

Love this light. First and only light I’ve used: keeps temps in line (83 on full blast in a 74 degree room). And I love that you can have the light within a foot of the flowers. Solid piece of equipment.

Great light

Excellent

Top notch light. Extremely efficient. Can handle 10-15 plants no problem in flower

Excellent light. Very efficient. Wish is had better penatration but these diodes are limited

The light is a very solid design, it doesn’t put off a ton of heat. Even at 100% We definitely saw a increase in yield as well Over all I’m happy with the light.

I don't have anything to compare it to, but it worked fine.

This light is tops. Can't really find much better right now! Top diodes, low heat, good footprint with decent penetration.
