Terribly fragile power connection.
Update: I had left a 2-star review due to the connector breaking off so easily on one of my panels. The company contacted me and sent a full 4-head replacement. For that excellent customer service, and due to the otherwise excellent quality and actual results, I'm upgrading my review to 5-stars. I've also added a photo of one of these units lighting my wildly successful Kratky hydroponic lettuce (the lights are on 16-hrs/day, supplementing a northeast corner window that is also lightly shaded by a thin jacaranda tree). Original review: Good value, good results with the plants. But VERY FRAGILE USB-C connector breaks off with the slightest twist or pull on the power cable. I like these, I own 3 of the 4-lamp sets. But one of them is now only 3-lamps. I guess I still recommend them, especially if you want to run off a 12V DC feed (off-grid solar) like I am. But BE CAREFUL and GENTLE, if you don't want to break off the impossible-to-repair power connector (SMD port soldered on by a robot).

Awesome customer service!
I enjoyed the lights and easy install for 2 months then they stopped working. I would not recommend for long term use. I upgraded the rating because seller reached out to replace or refund super fast. Will try lights again!

Repeat customer
Ordered a set for my plant shelf and I liked them so much that I came back for more. Not only do my plants love them, but the light is very pleasant for me as well. The color is like real sunlight, and I have the option of three different setting depending on what my plants need. I also like that I can set the timer for 16 hours (the other plant lights I have only went up to 12.) They were easy to attach to the wire shelves of my plant rack with the included zip ties. There's also adhesive pads if you want to put them on a regular shelf. Very functional lights, whatever your setup is.

Power Port can become detached
Purchase two sets of these, so a total of 12. The port is a USB-C which seems to be more finicky than other types and more difficult to physically insert the power supply (tighter fit). When trying to insert one, the power port popped right off, causing one of them to become completely useless. The other lights that did stay connected look great and work great. Please note chains are not included. This is just my setup.

Just replace my light guys! and fix your horrible support loop.
The item was working than just stopped for no reason, I tried to get it replaced as it is well within the warranty and just get the run around between this company and Amazon. Still no response in the middle of cloning plants.

Connectors super fragile and impossible to fix
I bought the 6 and the 4. The panels that the connector hasnโt broke on are great! Bright amazing light and my plants love them and grow really well. The timer is wonderful! Set it for 12 and havenโt had to touch it since. However the USB connector on the panel is super fragile and break EXTREMELY easily and IMPOSSIBLE to fix. I bought a three panel one after the first connector broke thinking I could just use that panel to replace the broken one BUT the panels DONT work with any other cord except the one it specifically came with. Thereโs also not an easy way to contact the company. Now Im here with 3 broken panels and three wires that canโt do anything and scared to try to ever unplug a panel bc the connector will break.

Best Bang for your Buck!
This is a very nice set. Well made with good connectors. All the settings work and the timer. You get a lot of light for the price. Probably, puts out decent EMF, but there are things that could be done to mitigate that. I like having the 16 hr option for some plants. It came with options for connecting. They do seem a bit smaller in person, but they are light weight and easy to install. I actually just took a thicker metal coat hanger and used that as my support bar. You could use just about anything since they are so light. I even installed these above a top shelf with a small shower tension rod. My micro tomatoes were getting too tall. Lol. I will add that I think you will need 2 lights per shelf in most cases. They really produce very little heat. I would make sure also to at least plug them into a surge protector.

Great but donโt last
had a love/hate experience with these grow lights. When I first got them (purchased September 4, 2025), I honestly loved them. The brightness was great, my plants responded really well, and they fit perfectly into my setup. I even liked them enough to share on my ShopMy page because at the time, they were doing exactly what I needed. However, after about 6 months of use, they started flickering on and off. At first it was occasional, but within a few days it got worseโand now they wonโt turn on at all. For something thatโs used daily and marketed for plant growth, I expected a longer lifespan. Not even making it a full year is disappointing, especially considering how important consistent lighting is for plant health. To be fair, when they worked, they worked wellโwhich is why Iโm giving them a 3.8/5 instead of lower. But reliability matters just as much as performance, and thatโs where these fell short. Bottom line: Good performance short-term, but I wouldnโt repurchase unless durability improves.

They work
Lights turn on. Connections are fragile so set it up with some perminancey in mind. you can relocate the lamps but avoid disconnecting to prevent damage. The timer is a nice addition. Well rounded kit included some zip ties, In my set up I used some additional ties and plan to use the other 2 lamps when plants germinate. I did not use the "stick on supplied pads" There is very little heat thrown off so they are green house safe which may be an additional set up in the future. Side note: would be 5 stars but These are fragile I fear connecting/ disconnecting may damage otherwise Excellent and fair value! All in all Very Satisfied with these :)

Absolut Happy, pflanzen lieben es, junge wie alte. Eine ist allerdings bis ans Licht hoch gewachsen und hat sich verbrannt. Aber obwohl die Lichter in einem Regal am Fenster montiert sind wachsen die Pflanzen nicht Richtung Fenster sondern nach oben. Timer funktioniert einwandfrei
