Great light but quick failures too!
I purchased 2 of these lights.The lights performed perfect for 4-5 months but now, after almost 1 year of ownership, one of them has 2 rows of LEDs burned out and the other light has 1 row burned out.Have reached out to company multiple times but have not heard back from anyone after almost 3 weeks since first contact for warranty service.Do yourself a favor and buy somewhere else...

Very Satisfied So far, Will update on how Plants like it
Very Satisfied with this COB, Have never tried this type of LED Light, but I am EXTREMELY Satisfied with this. The Concentrated angle of the Light seems to provide better canopy penetration. I only have a LUX meter, not a PAR, meter, but this is still measuring about 20-25% higher than my Standard 100w Led Grow light from the Same Distance.Also, I like the spectrum of this - though I dont know if the plants will as much.It seems to have the Red / blue as other lights, but it also seems much much 'whiter' like actual daylight, which not only gives off a real nice bright light, but also helps to even out the other grow lights in my room.UPDATE:Ive Had this light for a couple days now, and its definitely sufficient for my Growing needs. I have a Rose plant, two pansies, two Aloe vera plants, and other herbs nearby (supplemented with another lamp).My rose has begun flowering, which I could not get it to do even while outside in part sun. Its also great for my Snapdragons that I have growing nearby

Sub-par performance
For a COB that's supposedly drawing 50 watts, the performance is pretty underwhelming. After using it for about the past month, I'm fairly disappointed. It may be fine for starting a small cluster of seedlings - at very close range - but don't expect one of these to grow even a single cannabis plant to fruition - doubt it would even effectively veg a single auto. Don't expect much and you may not be let down; but I think your money would be MUCH better spent on a different product.

I currently have a handful of different led lights and with that said this is the best for the money
I was very wary on buying this light. I have plenty of education regarding led lights. I currently have a handful of different led lights and with that said this is the best for the money. This light is 800 watts of power out. 200 draw from the plug. They are super bright. Relatively quiet. Buy a couple of these and you will be happy. Also with the cob setup if a bulb goes out or fan they are simple to replace. Packaging was well assembled.

Go with a pricier one.
I had one and over two years bought two more. The last two were crap. One had a few LEDs go and the other had half the panel go out and fan sounds horrible. Unfortunately, it is hit in miss seeing a lot of these panels are the same with different stickers slapped on. Good luck. Buy it and maybe you will be happier than I.

Great light so far
Great lamps for the money, I am using 2 100 watt lamps on a 30 gallon planted aquarium I added standoff legs which I made from steel 1/8" wire to elevate over a planted aquarium. So far they have provided great growth and my plants are pearling wonderfully, almost on par with a kessil I will update if there a any functional issues. Refer to pics to see the wire stand off legs which work great.

Too much heat
I've got two of these guys in a tent and they give off so much heat. I had to crank up the ventilation to keep the temp below 95F. not sure if its a product defect???.
