PARFACTWORKS 1000W COB LED Grow Light, Full Spectrum Including UV&IR, Led Vegetable Grow Light for Greenhouse Hydroponic Indoor Gardens All Plant Grow Phases

First off, for the sake of honesty, I may get a $3 reward for being 1 of the 1st to review this product. I know that's quite the payout but you will have to trust me when I say I'm not just doing this for the fortune and fame. I'm doing it because I feel it's the right thing to do for the people reading these reviews and also for the people manufacturing the product. Everybody deserves the right to hear my opinion! So let's get down to business. I purchased the the 640w and 160w because I had purchased a 160w close to a year ago and was really impressed. Havent got to flower with my new set up but I used my original 160w in between 2 cxb3590's and I felt it performed quite well. Light penetration is solid where blurple lights leave something to be desired. The 160w out performed my hillpow 300w in both veg and bloom. Love the veg/bloom switches, wish it also had a dimmer though. Solid construction and as I write this, all 3 pfw units have been on 7hrs and all 3 are cool to the touch on top. I fully endorse this product line and am looking forward to using it for a flower cycle as the main attraction instead of a last minute throw in to fill a hole. I think my PFW set up will give my cree cxb3590 set up a run for its money. Will update this review through my flower cycle, which I plan to start soon, and if it goes terribly wrong I will gladly take all verbal abuse from anybody I steered down the wrong path. I've spent countless hours researching lights over the last year, purchased 13 total and 7 different brands. So far I have at least some regret about 7 of them and 6 I'm totally satisfied with. My PFW's are 3 of those 6. My only regret is I wish I had 2 of the 320w or 4 of the160w instead of 2 160w and a bunch of lights I probably wont use boxed up in my closet. Oh well, live and learn right....?✌

One cob was out. Just opened package. Its a loose wire on inside going to ballast, pushed it back in to plug. Cob works. One side of ballast controls blue and red an one side controls cobs. So if you buy this light, and a light is out, thats were I would start. 3 stars because I fixed it . I bought a 2000 full spectrum from parfactworks an its awesome!

Although my light stopped working after a couple months, the seller and not amazon, did remedy the issue. Sent out new driver and led boards at no charge. Also sent out a completely new light for my troubles. New light is slightly different style than the current ones he offers. Uses more cobs on a smaller case, very similar do the Optic 4's. These leds are probably your best bang for the buck on amazon or online anywhere for the amount of cobs and diodes in each fixture. Once I was able to reach out directly to the supplier everything went fine. Would recommend again. I do have two of the 2 cobs fixtures and one of the 4 cobs fixtures that I purchased, and one new 5 cobs fixture in the size of the 2 cobs fixture. Nick from Parfactworks is good at customer service. I do use this for cannabis, which requires specific color temps and intensities.

Theu say 5x5 but for fruiting plants you need over 1000 ppfd theu only have it on a small spot. You can take off the lens but then you don't really know anything about the light and your growing on your own.

Finally purchased my 4 COB LED 1000w from Parfactworks. I have to say.... I am impressed!!! Within 5 months. I harvested a successful grow!!! Honestly no games or gimmicks this light does the job. I highly recommend removing the Cobbs during vegetative state. During flowering transitional period Switch to BLOOM ONLY. Once in mid flower finish her off in Full Spectrum.

It ain't all that... but it works good and I'd rather get this than anything above $300 to $600 due to the lack of quality. But an excellent product. The light gets weaker after 2ft radius (4ft circumference) within about 6ft high. Lux idk i got stoned writing this...

Started bright and promising. 38 days later the light is failing and I can’t send it back and the light comes from China. No one to talk to in the United States to get a replacement or even talk about the 3 year warranty it’s supposed to have.

I read a bunch of reviews and was still unsure, but desided to give it a shot. I was really blown away! Haven't come across anything as good for the price, and paired with 2 Mars Hydro sp120's my spare room is a jungle of fruits and vegetables!

It works great.
