    I Got tis light 3months ago and its working great the plants are getting all the light they need pretty a green . even under cover leaves . just wish they made a 900watt!!!


    Works for my space didn't think it would heat up as much as it does but an easy problem to fix with a extra fan. Led believer!


    I would give this LED light a B+ because there is one white light on each of the spheres that is burnt out and notfunctioning properly. I would give this light an A+ otherwise, if they were all working. However this defect did not affect the productivity of the plants, and the light was very intense and bright. The plants all blew up like monsters, and I was very satisfied with theamazing end results. Also, I had a much lower electric bill, than when I wasusing HPS lights. And, the nutrients I bought from Grow-ace are the best in the business.GROWACE RESPONSE: Thank you for your honest review of the product. All of the Advance Spectum Max S Series lights come with a UV spectrum built into each of the diode clusters. This UV spectrum diode is placed specifically for medical plants to promote resin growth during the final stages of growth. UV spectrum wavelength is not visible to the human eye due to where it lies in the spectrum map, however rest assure that it is highly visible to plants!

    This light has really impressed me so far. It fits in my grow space, in a nice and sleek fashion, the LED's are extremely bright and my plants are reacting to them well so far. Can't wait to see what they yield when completely full grown!!! Anyone who is skeptical of LED lights, there is no need to be any longer, this is the light to grow with!

    Upon purchasing this LED panel, I was a bit concerned but the people at GrowAce reassured me and its been the best experience ever. the item is very well bulit in a full metal housing. It includes 6 fans which cool off the panel which doesnt give off much heat anyways. best price around for a 300w LED panel. thank you growace, i will be a returning customer for sure
