Grow Light,40W Ultra-Thin Panel Grow Lights for Indoor Plants,316LEDs Full Spectrum Grow Lights for Under Cabinet Plant, Grow Lamp with 3/9/12H Timer,10 Dimmable Levels for Plants Growing (4pcs)

Two of the four dont work. Cables are fine, it's just the last 2 that won't turn on.Edit:19/03/2025Seller reached out and sent me a new set alongside my replacement. All lights work! You can see in my pictures that the grow lights are working on my stock, snapdragons, poppies and Shirley Temple peony bare root (peonies are extremely difficult to grow in zone 10b so i am ecstatic that it is responding well to the grow light).I am surprised that the adhesive hasn't come off and the timer is consistent and easy to use.Thank you seller for reaching out to me. I wasn't really expecting them to contact me for a replacement.I will be buying from them again because now I feel like I need to plant more.Edit 28/03/2025:My plants are growing and im running out of space. I have 8 grow lights going right now and I don't know what to do with all these plants now.Im still amazed at how great the timer works and how the stickies haven't melted off.10/10

I bought these after having extended bendy arm like grow lights. Those bendy ones worked but just made things look bulky and chaotic.I can't use the provided zip ties and it came with holes but no little screws so I ended up using the 3m sticky squares. I really didn't want to go that route because I didn't want to take the finish off my Ikea book shelf but it was the only way.They fit nicely and look good and my plants ( aloe, succulents, orchids, air plant and many propagations) seem to be thriving. I love the look as it's much cleaner and streamlined. I was right about the finish being removed if the strips need to be removed or relocated as I miss set one and had to reposition. It's something I'll deal with at a later date but it's something for others to be aware of. The timer feature works great. I don't get any heat from these and they are plenty bright. I'd love to get another set of these because they are pretty great.*edit update 10/2024I got my 2nd set of lights. I set it up on another Ikea shelf same as before but was now mindful of the positioning. I wish these were a liiiiiiiitle cheaper, say $20 vs $25. Or that the panels were larger so I'd only need 1 panel per shelf. I do love how these work and the look they bring to my plant shelves. They are much more streamlined than the ones I mentioned at the top of my review. The only other thing that could make this better aside from small screws would be sticky clips to hold the wires so they're more hidden on shelves. Otherwise it's a great product.*edit* 1.17.25My first two sets of 4 lights are still going strong for all my plants. I purchased a set of 2 lights for another Ikea cabinet because my cats will not leave my spider plants alone. These guys need some TLC my hope are that this helps them grow and thrive. My only regret is that I did not do this sooner because I think the setup looks beautiful and there 2 sides for airflow. The light is nice and bright, and these two at the very top will be sufficient for all plants set under it since the shelves on my cabinet are all glass. I've included more pictures of this new setup.

Love these! They are easy to attach and use under my shelves, have worked perfectly. I've noticed a difference in the plants growth. They were also nice at Christmas when I moved plants away and put a Christmas village on the shelves and could dim the brightness.

The light started out well. Worked as adverrtised. 2.5 months later the light just turned itself off. Now when I try to turn it on, it will flicker for a moment and turn itself off again. I have the two panel version. When I plug only one panel in, it sometimes works for the single panel, but the other button functions do not work. And when I try to plug the second panel in, it turns itself off and won't turn back on with two panels connected. Disappointed that it only lasted 2.5 months.Edit: Seller contacted me regarding the issue and offered a refund. I asked for a replacement instead and they agreed and sent a replacement light. Hopefully the replacement will last longer. I changed the review to 4 stars due to initial issue. I am still happy with the light itself, when it's working.

These panels were so easy to install. It even comes with multiple options. Thick 2 sided tape work great for under cabinet or you also get a bunch of zip ties- i used these for the wrote shelving on my inside small greenhouse! It has multiple light settings AND a timer. My seedlings are loving it! I got 2 sets so I can have a shelf that needs 12hrs and the other only 8.

Great lights and easy install. I used two per shelf. Love the timer!

These lights work really well for my planted terrariums on bookshelves. The panels are very thin and easy to use even with a small amount of clearance. Additionally the lights don’t get very hot, even when running all day and don’t create heat issues in my terrariums. I’m working with low light plants and these lights do well, but I expect a plant with higher light needs might struggle without additional light. The built in timer isn’t exact, but if you don’t absolutely need all your lights to turn on at exactly the same time, the timer works great.

Easy to use and setup. Affordable. Easy to adjust.But not as bright as I would have hoped. Bright enough for small seedlings and plants like greens that don't need much light. If you want vegetative or fruiting levels of light you need to double up (as in 8 panels total) and then it's getting there. Even then to get a DLI of over 20, it has to be on 18 hours. 12 hour DLI is 14.2 which is good enough for me as my seedlings will be going outside soon as weather permits, long before they get to the fruiting part.I mounted mine on the underside of a full sized cookie sheet in a baker's rack. The female power connection on the PC board broke off rather easily on one but that was my clumsiness. I think I can solder it back.Will be buying more of these.
