What Do Our Customers Say?
I am replacing a 150w HQI and when I put this over my tank it was almost the same amount of light. If anything it is a little bit brighter. It looks like a 20k bulb with it being a little bit bluer. For bucks this thing is a steal.

Alick Raglan

I am an older guy - been growing only a short time. The results have been very good.

This purchase was actually my third 90w LED and watt for watt the best lights available.

Micah Orlando

This LED light has been great for growing a very large banana palm.
