GUANHONG LED Plant Grow Light 1000W Ajustable Knobs Full Spectrum Panel Growing Lamp Suitable for Greenhouse Seedling Veg and Flower(Dual-Chips)

The first one I ordered, the red lasted 4 hours and just shut off. Sent it back, got refund, left review. Long story short, company Rep. e-mailed me asking to try the same style again and change my review. Received the light few days later, it has been on 12/12 for several weeks now. It seems they built it with better drivers for the red, both veg/bloom are very bright, little bit brighter than other 1000w LED I have. The main thing is the light is working the way it should, hats off to their R and D department.

I have to return 20-25 over the past year due to them quit working the first week or two but as long as they keep exchanging them for free I’ll keep replacing them👍

I bought this without reading the reviews and was nervous. It’s lasted an entire grow with no complications. I just bought another for a second growing area. Love them both.

Power issues, blinking cutting out, pretty cool for junk danger

The media could not be loaded.  DO NOT BUY THIS LIGHT! I have 3 of these lights. On the 2nd day of use each red light and center started blinking on off on off...3 days later now, the blue and center light has burned out completely on 1 of the lights.Amazon is refusing to replace the light. Due to reviews, Amazon and seller, GUANHONG LIGHTING is aware of the DEFECTIVE LIGHTS... BUT KEEPS SELLING ANYWAY, THATS FRAUD!

I really wanted these lights to work they are very bright I tried many of the lights and every one I ordered have been defective...they put out a high amount of heat which sometimes could be good but not if your plants are to hot already...do not buy these.. and btw company that makes these the problem is in the drivers one usually works and the other seems to malfunction so look into getting or making better drivers...

Not sure if mine is defected, but after putting blue light knot on 80% or higher, the light started flashing blue and red in seperate sequence. Basically, i was able to veg my plants under this light, but not able to flower. Hope this helps potential buyers

I purchased this light and it seemed to be brand new but when I plugged it in and I turned the dials all the way up the light would not stop flickering
