    • NICE AND BRIGHT - - -
These grow lights are very bright and seem to perform as advertised. But it seems that with all electrical products these days, once in a while some products come from the manufacturer with an unforeseen problem as it happened with these lights I had purchased around X-mas time. Just put to them to work around the middle of January '25 and found a little over a week ago, today is Mar. 02-'25, that one bulb had a row of 4-LEDs burned out. Don't know exactly when this happened since it is very difficult to see, due to the enormous brightness of the other still working LEDs, which also makes taken a picture impossible to do to proof this. Contacted the seller and explained my problem. After a couple of back-and-forth E-mails, the nice seller's representative explained me how to go about having it replaced under their warranty for the product. It took just 2 days after the last E-mail from me to them that I had a perfect replacement shipped to me ! THAT'S SERVICE ! As mentioned before, these are good performing lights, and I hope that this will stay this way for the 50,000 hrs. that they have them rated for and that in this case it was just a fluke. If these go bad again shortly, and I hope not of course, I will have to change my rating accordingly. For now, I can recommend them with confidence due to the excellent warranty service I received, and the fact that they are on sale. ... show more

Extremely bright grow light. My plants LOVE it. I liked it so much that I have now purchased three lights to start my tomato, strawberry and celery plants. Highly recommended.

    • Definitely seeing growth, works amazing when you can't find direct sunlight in your home.
Item Package Quantity: 1 Color: Full Spectrum 4000k
I ordered these because I wanted to continue growing my jalapeños and basil during the winter months. A little problem with shipping caused them to arrive a bit later than expected, but it happens so I didn't mind too much. My plants were starting to show signs of needing light, leaves yellowing with some even dropping off. When it arrived I plugged it in, happy to see both fit and worked without issue. Using a timing schedule, I used these daily to give my plants the light they craved. Sure enough, the leaves returned to a healthy green, new leaves began sprouting, and a couple weeks later peppers were coming in. Saved my plants and let me continue the growth and production of peppers. No flickering whatsoever like many reviews of similar bulbs seem to state. Can't speak about the lifespan because I'd have to have it for much longer, but they have lasted for at least 5 months so far at 14 hours per day of use. Other bulbs will sell you a single bulb for about this price, so two bulbs for this price is a good value. Side note: Seeing as there are so many different bulbs of this type, with various spectrums and qualities, I gave this a 4 star review, as there may be better products out there. That being said this is a solid product that absolutely does it's job. ... show more

Super bright! I bought as a replacement for my bulb that goes out about every 4 months. I wasn’t expecting it to be this bright! I’m excited to see how my plants do, and how long it last.

    • Nice light
Item Package Quantity: 1 Color: Full Spectrum 4000k
This light is exceptionally luminous and beneficial for nurturing plant growth. The bulb's guidelines suggest suspending it around 10 inches from the plant, but I have installed it in a ceiling socket approximately 4 feet away, and my plants seem content. Despite its brightness to me, the light reaching the plants creates a simulation of a cloudy day, which they seem to enjoy. The comprehensive spectrum light has supported my plants from their seedling stage to flowering. The plants appear content, and I am delighted with the outcomes of using this bulb. ... show more
