Review on Phlizon 2022 Advanced PL-1000 Plant LED Grow Light With Samsung LM281B LEDs & Brand Driver Dimmable Daisy Chain Full Spectrum Grow Lamp For Indoor Plants Led Growing Light For 2X4Ft Coverage by Andrea Young

These are very bright lights and perfect for my seedlings. They have great coverage. I have mine on the ceiling because they are so bright my adult plants leaves started curling. Its weird because they are only 20 inches above my 1 to 3 month old seedlings and they love it. So far they are the best I have found for the price. I have not noticed a big difference in my electric bill and Im running 8 lights all day every day on high. My plants seem to do better under the lights than in full sun. The bonus thermometer is really nice. You can set it to warn you when humidity or temps get above a certain range. I grow Desert Roses aka Adeniums to sell.Update: I still love the lights but so far 3 out of 9 ordered have been defective. Two of them either stay on or turn on alone and the third just quit working period. After looking at it more closely I can see where the aluminum piece on the top had been removed and installed incorrectly. It was hanging on by two pieces of plastic screws. Had it not been sitting on the top it would have broke. I am sure I got a refurbished light. It wouldn't be so bad if I didnt have to have them right now or my seedlings can die or get stunted. Just one light less is a huge difference. Now I have to wait who knows how long for a replacement.
