250W COB LED Grow Light Full Spectrum Including UV and IR Plant Growing Lights Lamp for Indoor Plant Veg and Flower Full Cycle

This is a high quality light! here’s what this light offers:First off, it was packaged very well. Lots of foam on all sides of the light. Upon plugging it in, I noticed two switches; one for the cob (about 50 watts), and one for the double chip multi spectrum leds which have lenses (about 46 watts). The cob lens is very easy to remove and clean! With both switches on there is a nice red heavy glow, surely fantastic for flowering! Just the cob switch on is a nice yellow/red heavy hue but I’m sure I will always have both switches on. Overall I am very pleased with this light and will be buying more in the future of the larger 640w model. It is very solid/heavy dut and there is no rattling when shaken. High quality grow lamp! Will update with results in a few weeks.After 5 days of use, I am in love with this light. I switched it out for another light I had over a 16x16 inch area with three flowering plants. The ones under this light have denser buds, extremely stiff stems, and the leaves are praying so hard at 45 degree angle which means the plants are loving it. All my other lights keep plant leaves at 90 degrees. Seriously beautiful. Makes the plants look so vibrant and you can see every detail unlike the old lame blurple led lights. Very very pleased. And I am now confident that the 4 cob model could easily flower a 3x3 tent with great results.Edit 12/13/18Very intense light. My leaves were burning with the light 12 inches away so I moved it up to about 16 inches above canopy. At 16 inches, in the center, my light meter reads 85-90,000 lux. That’s essiantially sunlight! And the lens makes for good spread of light without hot spots. Intensity doesn’t drop steeply as you move away from the center.

I purchased 4 of these. Importantly, they are all identical in every way, indicating a good manufacturing process. These are quality. Nice reflector and cob lens. Nice powder coated aluminum case. The Cobb and the 5W light array are each powered by identical drivers rated at 90-277V AC input, Output- 30-40V DC, 1.2A, 55W. Fan is 12V DC, 0.12A brushless. Daisy connector accepts standard wall-plug and is rated at 13A, 250V. Attempting to daisy more than 5 will overload the current rating. The heat-sink is adequate, but the fan seems a bit small. Just blow some extra air across the top or through the side vents if possible. Cut the stated coverage to 2x2 veg and 1x1 flower. I'm using 4 of these to supplement a KIND 600L in a 30x60 inch tent floor space. The plants like the spectrum from the Cob. The 5W array is more blue than I expected. The Cobb is a warm-white. The light is reasonably bright and 4 of them running both channels has only raised tent temp 2-degrees over the KIND 600L alone. Cobs are the way to grow and are certainly the best start to finish grow-light. They are the most efficient and therefore produce less heat. My Timber Vero chip cobs blow away anything I have ever used, including the KIND 600L-PARFACTWORKS combo and does so using nearly 40% less power. I'll update here if I experience problems or need customer service.Update: Just over 1 year later, all 4 units are still going strong. I'm not sure how much brightness they lost, but my plant's don't seem to notice. The funny thing is, my Kind light burnt out two of the 10 clusters.

Less than 200 hrs of use after Daisy chaining with 2 parfact works 1000s I lose an led.....terrible ......the 1000s have approx 2000 hrs and working fine.....these old White models seem like crap compared to the new black models......

For the money, this is one fantastic light. Can be daisy-chained, has essentially four functions (off, 5w LED on, COB LED on, and both LED's on). Fan for cooling is fairly quiet and light does not feel hot to touch, even after 14 hours of run time. Light spectrum is comparable to more expensive COB only LED grow lamps. For footprint, this light is unbelievably bright. Plants are responding well so far. Light is positioned roughly three feet above youner growth to prevent burning. Be mindful when setting up your own grow. Build quality is sufficient compared to similar lights through CF Grow and Canagrow, but excellent overall when considering cost. Greatest value for money spent, if light can hold up to long term usage. Comes well-packed in plain cardboard box. I will update review after long term usage.

Lights is okay. Not bright enough for dense flowers, poor canopy penetration. Would recommend for seedlings but even than the spectrum is too warm for proper veg. Better off getting a quantum board

good little light. i have 2 in a 3×3 and they are preformimg well.. give off less heat than my mars hydros and i really like working under white lights.. im still early in my.grow but im very impressed so far.i will update after the grow.i changed my review to 3 stars.. i do like the white light but the lights have steady gotten dimmer over the weeks.. at $72 i think you can do better. i got mine for $58 and well... In retrospect i would of spent more and purchased a cree cob or a hlg.

i have this light in a 2x2 its the perfect light for the setup if you have two medium plants or one big plant im sure would be more optimal due to the flowering lens it creates a smaller penetration area like 1x1, but I have lens off through flower and the buds are getting more dense than the buds in my 4x2 with a vivosun led... update 7/3/19 one diode already out light is still awesome will be contacting seller shortly

Okay so let's talked about this little beast!!! The footprint is awesome I use the light mostly for veg because I only have the 250w and would need severely to flower the area I have. Which I could easily with the daisy chain ability!! I can veg a 3.5 by 3.5 area with this light no problem. For 70 bucks!!! That's just crazy. I am going to get several more asap!!!!
