Bought these lights for indoor plants. Arrived and are well packaged. Set them up right away and worked well. Used them for a few days and then due to rearranging the room, took them down and stored them on a table. A couple of days later I hung them up and went to use them again. Sad to say the second unit was not working. Plug it directly into the main line and they flashed a few times and cycled the different color modes on their own. Reconnected to the first set of lights and did not work. So I emailed the company directly through their web site. I explained what happened. They responded within 24 hours and apologized for the issues asked for further documentation to help to resolve the issue. During the time I was waiting for their response, I investigated and found out that the pins in the connect cord attached to the second unit needed to be pushed in. Once I did this the unit worked. I relayed this to their customers service and asked if they could just send me the defected cable because the lights were fine and I could fix it myself. But I was afraid that unplugging the unit might dislodge the pins rendering the unit useless. Again, within 24 hours they responded and said they cannot send the cable, because they do not inventory the parts. But offered a very fair and viable solution and within four days I received replacements for the lights.So, do the lights work? Yes. They output a good amount of light. They are set for the spectrum plants need to grow, flower, or to fruit.They are very light and have many options for installation for a variety of set ups. They provided cable ties, Velcro strips, and adhesive mounts.The cables are designed to be water tight and therefore can be used in a humid/wet environment. You can either connect the lights close together, or with the added cable move them up to 3 ft (1m) apart.Does the company stand behind their product? Yes. The company was quick to respond to my emails, it is stated that they will respond in 24 hours and they did. The communications were professional and polite. They stood behind the product and offered a vary viable and fair solution to my issues and I am very happy with the results.I would recommend the product and the company.

Got these for installation on a tall and narrow IKEA shelf for my indoor cacti and succulents.Very simple to install, and with the self adhesive pads, placing the on the underside of each shelf was fairly easy (they're very sticky, so make sure you measure or mark where you want them to go). I liked the little snap in hangers that created a gap between the panel and the shelf for heat dissipation.I've had no issues at all with the timer, it has turned on and off as set (I haven't seen what happens after a power outage, but that's a fairly rare occurance so only time will tell).My light measurement app shows a very good lux reading, so I know the output is okay, and my buddies have responded nicely.My only I wish is that each panel were a tad longer and wider, maybe 12" x 6", but overall after four months of use I'm happy with these lights. They seem quality and well built, so I hope they last for a long time.

Nice lights. They link nicely together. Nice and bright and you can control the color options easily. We created a built in book shelf with these lights to grow herbs.

For: Barrina Grow Lights for Indoor Plants, 20W (2 x 10W) Full Spectrum Ultra-ThinPros:1. easy to use - I bought 2 sets each with two lights2. connects easily; I was able to connect 3 together on one power supply so they cover almost 10-feet of wall plants3. has multiple brightness settings4. starts and stops accurately depending on the time setting you choose5. has kept my indoor decorative plants alive so far - they are thriving6. has remained stuck to the ceiling using the provided snap-in adhesive connectors7. does not generate much heat compared to regular grow-bulbsCons:1. Unfortunately, the design has a start-unit which has an extension connector on only one side. This prevents you from being able to string 4 lights together.I was able to do this -start-unit <==> extension <==> extension <==> power-supplyleaving me with an unused start-unit since it has a power-connector on just one side. I wish they had given the opportunity to use at least 4 units together. I guess the power-supply would have to provide more power to allow that.2. The controller is too close to the connector on the light. When the lights are mounted on a 10-foot ceiling, the controller is just a little too high to be able to make changes easily. The cable from the controller to the light should be at least2-feet longer3. the connecting cables are all black. I wish they had a white option, so the wires were less obvious on a ceiling painted in a light colorIf Amazon allowed, I would have given it 4.5 with a half-star removed for the cons instead of 4-stars

I have two ikea cabinet greenhouses in my home, which I fill with Philodendron, monstera, and a couple hoya.Some lights that I've purchased in the past, although good, were all wrong for these plants, which are happier with weaker light.These lights are PERFECT. Not only are my plants happier, but the hue of the lights are not as harsh and add a nice ambiance to the room.They are a bit on the short side, but as my plants like indirect sunlight, this still works great for me.

I have been using these lights for a month already and so far they have worked well. They do have settings for brightness, color spectrum, and timer which is very convenient. They are well made and I feel like they are good for the price. They were easy to install.
