SAYHON

This light is very efficient. Its the best grow lights. I've seen considering $/umol. I have it set at 30% because it's so strong.On the other side I have the SH2000. That light is also very strong. Both models have the supplement bar built into it. Highly recommended this light to everyone. No need to spend $$$ on other brand that perform the same.

I've gone through a couple of lights and this one by far is the best grow lights I've purchased. the light is really well made .the light barely gives off any heat and very bright . The dimming feature and UVA& IR supplement bar is a plus . This grow light wont disappoint. My plants love it .I would definitely recommend . Great price.

I do not have fancy equipment to measure PAR or electricity drawn from my wall. I do know these are great lights. I believe they are on par, if not possibly better than my HLG 200. My buds are frosty thanks to sayhon. I am relatively new to growing cannabis since it became legal in my city and have only grown auto flowers.Best grow lights!!!
