      Customer Reviews

      Based on 17 reviews

      Awsome light.. no heat bright as heaven.. can't say enough very efficient..


      Awsome light! Sturdy and well built over all 10 out of 10!

      Phenomenal light

      Does everything you want to and it’s adjustable with brightness, so if you don’t need a lot of light for say a smaller plant you can adjust and then bring light levels up for flowering. Noticed amazing growth even with 3k and really huge flower development! They have amazing customer support as I ordered the wrong socket type and it was corrected right away. I would say HLG is the top of the board on leds right now even above those higher priced conerical leds plus none can match this lights and the upcoming efficiency. Also any reviewers saying this light runs hot is absurd, or they simply have this light in a still environment with no airflow at all. I don’t even have a fan in this light just airflow circulating with my ceiling fan and it works more cool than cheap leds with built in computer fans. Cheers!

      so far so good!

      not much to review great product. New to lED lighting I now have two setups(lED's) I like this light 5 stars from my peppers as well

      Bright Light waiting to use

      Haven't really gotten to use it yet since things went south for what I was intending on using this light for unfortunately but what I do know is that this light is bright as heck and I like the more natural color light of it.
