Fantastic performance! Lights are unparalleled for the cost. Have dozens of these running living soil beds. Highly recommend!
This light is the best light I’ve gotten so far.
Ordered a 300L and liked it enough to get this 350R! Happy with the results from both, they don't produce much heat or use much power but yield top quality flower.
I regret the purchase of this light. The light does not perform as promised and HLG customer support is likely the worst I have ever encountered. The wire hangers and the dimmer switch were defective. The listed hang height of 15 inches over the canopy in flower proved to be false. I ended up having to tie down the flowers so that I could hang the light at 32 inches above the canopy. At that height I could not raise the light above 147 watts without causing further light stress to the upper canopy. HLG did not respond to my emails. Led Grow Lights Depot attempted to help me but HLG put all the blame on me without offering any assistance. “ if plants are not happy then it might be something the grower is doing incorrectly. “ HLG providing support for their product. Lol. If anyone is looking for a light I’m selling it for a very low price.
This is my third light from HLG and I have nothing but praise for it. Thanks HLG for a great product.
