    • Fantastic Value for a Great Light with super Cool Features!
Size: 2x4
This light is rock solid! To be honest, I was shocked how nice it is. We'll see how well it works with my next growing project. And the coverage of the light is perfect for my 2x4 grow space. Goodbye HPS and florescent bulbs.

    • Very bright, adjustable intensity by quarters. Happy plants.
Size: 4x2
I bought these solely based on a YouTube comparison video that found these were the best bang for your buck when tested against similar products by multiple popular brands of LED grow lights - using the same crops, and in the same conditions (sorry, I forgot the user's YouTube handle). I haven't regretted it and was so happy I recently got two more. I like that I can dial up or down the output, though I have mixed feelings about it being selectable only in 25% increments - especially since I use it quite a bit closer than is recommended (maybe 6-7 inches or so), to conserve space. But I've found most of my plants only get stressed at the rather intense 100% setting. They do produce some heat so keep that in mind if you use warming mats for germination (I do not). ... show more

Great!! Heading into winter, my sweet little herbs started to shrivel and I found myself accepting their death when I decided to give this lamp a try. It’s exceeded my expectations and I’m just getting started with it. It revived my basil plant in just a few days and now it has more new growth than when it was healthy. I’ve also been able to start some seeds, so far thyme seeds are the first to sprout with some cute little green pips. I started with the light on 50% and have now increased it to 75% power and the plants seem to be loving it. This purple vine thing has even flowered after just a few days of exposure to this light. You can see in the video how the light intensity changes from 25% to 100%. I have it rigged temporarily right now, and I have it plugged into an Amazon compatible outlet so I can have it run on a schedule. It does not have any sort of programming capabilities of its own, so without that I’d have to turn it on and off every day on my own. I’ve been using the sunrise and sunset schedule and it seems to be working well. Overall, highly recommend this lamp for indoor growing, and I look forward to fresh herbs all winter. ... show more

    • Lovely grow light
Size: 2x2
I am using this for my potted citrus trees and sprouts. It's working well so far. It's only been about a month or so. The set up was easy. It's very easy to use. It does give off some heat, which is nice during colder months which is a random plus. It's not a lot of heat though. The controls on the side come with different % of light level you want to use. There is an ability to use it remotely but I did not do that. It was easier for me to use a Smart Plug instead to turn it on and off. Basically no noise. It feels sturdy when holding it and hanging it up. I believe it's only 1 color option. I do not notice any crazy change in my power bill with this either. You do need to keep in mind that when putting your plants inside from outside that you'll need MORE light time. Maybe do a 12-16 hour on and 6-8 hours off. ... show more

    • Great starting point and even better than most other options out there
Size: 2x2
We’re versatile for a single plant to multiple plants. Provides more energy for plants and is very easy to adjust during different times. Price is reasonable for all the benefits of it. Great all around option if you’re new to growing.

    • Bright & doesn't work with my setup
Size: 2x4
Ok. I gave it a high rating because how its meant to be used... it does really well. But it unfortunately doesn't suit my needs today. It may in the future. But right now it is a regrettable purchase. One big note. You must where eye protection. Even on 25% this thing is very bright. Like I could (jokingly) probably illuminate my entire house on 25%. Including the basement. Pros: this thing does what it advertises and is crazy bright. Im not going to go into detail as you can read all the specs and yeah its great. Cons: the light appears to be designed to work with there grow tents. Which i do not have. I have a 5 rack wire shelf. I was hoping this light would work for one whole shelf thats the shelf I use for my tallest plants. It doesn't. The light out of the grow light will only illuminate one 10x20 tray. And it does so spectacularly. But it also absurdly expensive 1:1 tray. Now it might be that on brighter settings far enough away it might cover more trays. I just do not have the space for that kind of setup. I regularly have 16 trays. I would need 3-4x the space to use this. But in my setup, turning the light high enough to give outer plants enough light would cook anything directly under it. So for me this doesn't work. I am keeping it though. I may configure one zone for one that need more light or im sure ill find a future use. But right now its back in the box and shelved for the season. ... show more
