Opinions please

Nice little light, good quality price and complete spectrum for full cycle. That being said, only problem I see is it's low power. You will need 35-50w per square foot to flower your stains up to their potential. So this light is 100w at full power so it will be perfect for a 1x2 space or let say, a 2x2 for vegetation.... Like a lot of growers I am sitting on a box full light that don't really do the job. Wasted money is money spent on equipment that don't do the job. So it depends on what do you want to do with this light and what are your expectations... Using LED at full power will results in premature lost of intensity of the diodes and the extra heat will damage the driver on the long run. Better buying a light with higher wattage and run it dimmed. If you are not scared to shop directly form Alibaba you will find cheaper and stronger light. While Viparspectra is a known and respected brand, these LED boards all remain Chinese knock off of the American HLG. If you stick around hereon GD, you will find out that Mars hydro and Viparspectra gives away (sponsor) a LOT of light for promotion. That would be a main reason why lots of growers here are using them.
