Dimmable feature is nice for plants with different needs. Plants are very full and bushy! The brightness adjustment works perfectly to help with veg vs flowering stages.
The quality is great. It outperforms lights he paid twice as much for. This light meets its specifications. Easy to assemble.
These lights (2) for my 3'wx6'tx6l tent keeps the temperature at or below 80° with only 2 small circulating fans &. I use my exhaust system to control humidity and odors. These have a good lux rating i got two and they are amazing nice low heat.
Best bang for your buck.
