This light packs a punch. I was able to grow seed to harvest of my little crop.
Heat dissipation: heat became a slight issue only because of the tent I was in that said once the light got warm it stayed warm. Something to think about if you don't have a way to control Temps while growing.
Quality: Above Standard by far
Cons: the dial for light adjustment is really nice and smooth, but being able to turn it off by the knob is a missed opportunity here. Only being able to turn it down to 5% is a bummer but not a deal breaker.
All things considered this light gets 10/10 from me, it's a great deal for high quality LED Grow lights under $150. It has the efficiency and power to keep your crops happy and healthy
