Hydropics 1800w cob Led Grow Light Full Spectrum for Hydroponics Greenhouse Indoor Plant Veg and Flower System 48"x24"x60" and 48"x48"x80" Grow Tent Kits and Package (800w)

I bought this light not expecting much after testing the PAR output of a blurple light. I tested this light as well as a 600watt hps. This 200w light really does give more umol/(m^2/s) than a 600watt HPS in the usable area. The 600watt HPS has a larger cover area, the effective coverage of this light is 2x2. Outside of that, your plants get almost nothing. Inside of that, you get as much light as your plant can theoretically ever handle.I've used 600w HPS for a long time and had not found any LED lamps that were really comparable, but this one is. You would need 4 of them to effectively fill a 4x4, though.

Absolutely loving the new lights! I ordered one and it had a noisy fan. I messaged the seller and received a new light while my old one was enroute back to the seller. I expressed my need for the light sooner than projected to return and ship again, and they were all over it. Thank you!As far as the light results so far, I am three weeks into flowering and stacking already ;)**UPDATE**I just plugged in the second light and have one of the diodes not working :/ To be continued....

This is the second of these lights I have purchased. The first I have been using for 2 months, it puts out a white light from all 4 COB's and it is performing well. The second light I have not had a chance to use yet as I just rcv'd it - so I do not know how performance is yet. However, when testing the light it has 2 COB's that are white (like all 4 on my first light) and 2 COB's that show pink light. I have reached out to the seller and will update my review soon.UPDATE 11-10-18 ..........Seller has been working with me to get another light. The explanation for the cob color difference between lights is that this is the newer improved light. I will be back in a month or so to update further. As of right now I am satisfied with the seller's response.

Okay. Let me first say, that the manufacturer did email me when I sent back the first one. Asking if they could help me. Okay, on to the 2 strikes....First one I ordered. I took it out of the shipping box and one of the corners was bent in, clearly was dropped, outside the shipping box. Since the shipping box had no damage. I sent it back for a new one. Second one arrived today. I unbox it and it looks great cosmetically. I hook it up and it makes an insane flapping noise. One of the fans looks stuck and it's trying to spin, but can't. After 2 bad ones in a row, I am out. Good luck.

This light is the BOMB,,I have several different led grow lights in this watt and price range,,,this one trumps them all,,,,I will be ordering more as soon as I can,,I usually try one to see how it performs, ,and I can tell you this light blows the rest right off the stage,,,,EDIT::Just being honest,yes lights are very strong and you need at l east 30 inches above plants in order for them to be hsppy,also the plants need alot of magnisium, (epsom salt)also the fan went out. PLEASE HELP as I need one asap ,don't know how to contact ,I also took the cover off,this light is very service friendly, but I need the part to fix (fan) so please help and I'll give a five star review again, I'm only changing cause I can't get ahold of the company for a replacement part,I'm way short of warrenty being expired, so I'm totally good there ,j even filled out the xtra year extention ,so five star down to two star until I get ahold of the company, thanksEDIT :replaced the fan with one I found in a obselete item, light is back in action , starting a 4x8 tent grow , since they say 800 watt equvilent I'll compare to a 600 watt hps, I'll even turn the hps d I wn to 300 watts so it a fair , we'll more fair comparison, I'm also going to add 100 watts to the led side to make it a a fair watt for watt led vs hps , results will be posted soon , we'll 6 months from now as itvtakes,awhile to grow ,cure

The lights are great, the customer support is even better! I bought two of these lights for a 4x6 growhouse to overwinter my citrus trees. The lights run warm but don't get hot. In a 70 degree room, the lights warm the growhouse up to about 88- 90 degrees, while the lights themselves stay cool enough to be touched. I have 2 lights over 4 citrus trees running 12 hours a day and the trees are greener than they were outside! I purchased 2 lights and 1 had a defective bulb. I emailed the company and they fixed the problem, no questions asked. I would absolutely buy from them again.

Looks like a good product and hoping for the best results.. But my item came with a cracked lens and the other lenses looked a little scratched as well.. which must've happened before it was packaged considering the box it came in had no signs of damage... just looks like poor handling on the distributor end..

I was skeptical about only paying $99 for a light but this light is by far the best led for the price. Pulls about 210w from the wall, and the PAR readings provided are pretty accurate give or take ~80u. Got 2 running in a 4x4 tent. Provides better light than my old 400w hps. Gets hotter than most LEDS. Beautiful white (slightly red-heavy), intense light. Most Amazon LEDS are blurple garbage. If you're broke and need a light worth your time and money, this is the light for you.
