Led Grow Light, 150W Full Spectrum Plant Light with High Par Value Cree COB and Switch for Indoor Plants Bloom Flowering and Growing

Using this for houseplants and hydroponics. The plants seem to love it so far. Some of the houseplants turned much darker green after a day under the light, and basil has turned dark green after a couple of days.It felt a little warm at first, but doesn't heat up beyond that. I've had it running for several days, and the temperature at the light has only gotten up to 92F at the LED's (78F ambient, so +14F).It uses 78W, and seems to be built well, with a lot of airflow inside between the heatsink and fan. It was packed well with dense foam, inside a secondary box as well, but upon starting it up, the fan was rubbing slightly. I pulled it up towards the fan grating, and it popped into place, so had probably had a little pressure applied to the fan during shipping, but was very easy to fix.The fan is fairly quiet as well, but you can hear it. It's probably as loud as a bubbler, or a small desk fan on low, not something that would bother you.It's very bright, lights up a good area and distance, and the light hitting the plants seems to be pretty close to white vs. a cheaper panel I have looks very purple.It's working great so far, puts out a lot of light. I'll update in the future as the plants progress.Update 2019-06-06Plants are really liking the light, my DWC looks overgrown right now! It's still doing great!

This is my first Cob light, but not my first LED light. First of all, I like that it is bright and has decent spread. It is made with Cree COB which is the top quality, although newer and more efficient chips have been made by Cree, this one is so much less costly than those. And I like my lights to be affordable! Still this is a great light at a decent price. To best use of this UFO 150w CREE Cob grow light, you have to balance distance from plant to achieve light spread and penetration. You have to take into account how dense and tall your plant is. Pruning and training are your friends with any indoor light situation. I find that where I have mine now it covers about 18 inches x 18 inches (flowering) quite well. Your situation may be different, depending on what and how you are growing. This is a great alternative at a great price point if you want to get into Quality Made Cob lighting, and don't want to DIY. Depending on your grow space it may be beneficial to buy a few smaller units rather than a big one. I like multiple smaller lights because I can get the light where I need it better instead of a concentrated area. Heat output is not bad for these lights either, but again you will need to plan for it, according to your space etc. It works great for me and my needs. Right now my pepper plants are loving it! (And that’s what matters, right?)

I am only giving 3 stars because the unit only lasted 2 weeks before the lights went. It was still on but the light was barely visible. I had it running on an 18 hour cycle. While it worked, the plants thrived! They grew 6-8 inches in those 2 weeks. Can't return it because I tossed the boxes it came in. Oh well, if yours works it is well worth the purchase.EDIT: After writing my original review I was contacted by customer service and they are replacing my light! Talk about quality customer care! I went and ordered 2 of the 300w just because of this. As long as they last their expected life I will continue to support Growstar!

This is a great light for its size, have it on the "VEG" side, works pretty good considering this is geared more for the "flower" side. If this had a 6500K COB instead of the 3000k it would be better for the vegative side I think! The bigger one would do much better for flowering, you would be able to keep it closer to the plant. this small one is good up to 20" plant MAX, its foot print is to small you have to raise it way up to cover the whole plant then the PAR drops off too much. The UV and IR are a BIG plus, dropped a star because it does not have any white 6500k leds. needs a little more Blue or different COB chip. Been on 18 hours a day for 2 months all the leds still going strong. Would recommend Growstar strong PAR for good price! Growstar's Thin flat panel light for 28$ looks more geared for VEG might try that one next, it has 6500k white added and more Blue!

Simply the best LED grow light I’ve ever seen. The quality control must be amazing because the item is perfectu built. The hardware for hanging is better than I’ve seen elsewhere. It does not get to take it to heart I really have no complaints. I did have some questions so I contacted grows hardware for hanging is better than I’ve seen elsewhere. It does not get to take it to heart I really have no complaints. I did have some questions so I contacted gThe vendor and he answered my questions adequately while being very pleasant. Great price. Great product. BbBy the way, the manual is among the best I’ve ever seen for any electronic device, even Had coporvplots of the emissions specta z. Of the 150 white one and the 300 W 1+ maybe some others Which day sale. Unfortunately I missed placed it and don’t miss place yours

This light is amazing. I just got it today and hooked it right up. The light has great quality and the light is very bright. It's also lightweight and it has fans. The light works. I will be ordering more. This is my first led light that I have used. This is a great product. The brightness is 5 stars and the quickness of shipping. I'm very happy with this light! The light produce little to no heat. I never used LED before so this will be my first. I have had heat issues with other lights. They shipped this LED light to me very fast and discreetly packaged. This light is brand new no scratches no dings. I highly recommend this and the other lights they have.

I purchased this in January of 2022. I did not get around to using it until now, April 1st. The light does not work. Cant return it with Amazon since you only have 30 days and I havent touched it in about 60 days. I will try to contact the company that makes the product and get a replacent or something. But out of the box it does not work at all.
