The lights have the manufacturing tolerances that remind me of swiss watches. I look forward to seeing how my plants react to it. Item works exactly the way it was described very satisfied.
This new lighting has us on another plane entirely. They are lightweight and don't seem to have problems in a very humid enclosed environment. Works perfectly for my summer porch plants.
Small and lightweight, a 10# command hook holds it up. Been using it for veg with my photoperiods and one autoflower. The cooling fans keeps the unit cool.
I also like the new design with the holes in between the leds lights, it helps the light run cooler than other i have purchased previously.
