Barrina Grow Lights Panel for Indoor Plants, 40W (4 x 10W), Full Spectrum, Ultra-Thin, with 3/6/12H Auto On/Off Timer, 8 Dimmable Levels, 3 Spectrum Modes, for Greenhouse, Seedlings, 4-Pack

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.

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.

Very easy to set up. light quality is great. My plants are thriving. Purchased 2 more sets. Definitely recommend.

For: Barrina Grow Lights for Indoor Plants, 20W (2 x 10W) Full Spectrum Ultra-Thin Pros: 1. easy to use - I bought 2 sets each with two lights 2. connects easily; I was able to connect 3 together on one power supply so they cover almost 10-feet of wall plants 3. has multiple brightness settings 4. starts and stops accurately depending on the time setting you choose 5. has kept my indoor decorative plants alive so far - they are thriving 6. has remained stuck to the ceiling using the provided snap-in adhesive connectors 7. does not generate much heat compared to regular grow-bulbs Cons: 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-supply leaving 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 longer 3. 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 color If Amazon allowed, I would have given it 4.5 with a half-star removed for the cons instead of 4-stars

The first set that I received from Amazon was broken. I had to send it back. They reissued me a replacement. I finally got the replacement plugged it in. Put the timer on and it is working fabulously. The timer works exactly like it should. The light does have few different settings. I like to keep it on the first setting.... My plants are thriving in this light, which is exactly what I wanted. The color is great to the eye.It's not super bright, but it's strong Enough for the plants. It was a very easy, easy set up you just take it out of the box and plug it in. The size is perfect. It is very thin which is exactly what I wanted.I didn't want anything too bulky. I just basically laid it on top of my greenhouse. It does get hot, which heats up. The greenhouse and makes it warm for the plants.

These worked great for the bottom of my bookshelf! My plants are thriving! The hung up nicely and connected well too. The timer works great and there are multiple options for different lighting.

worth it

Like the title says, I love the lights, the different modes, brightness, and form factors. Unfortunately the controller itself is infuriating. There's no "memory" on the controller so if you lose power, you'll have to reset everything from scratch and the default mode is "off". That means if you want to use a smart plug where you can say tell alexa or whatever to turn it on or off, or potentially use an outlet with a wall switch, you'll have to manually press the on button every time power is cycled. If you have crappy mains power or a storm comes through and the power blips for more than a couple seconds, you'll have to set it up again. Additionally, the timer is based on 'when' you press the timer mode button. There's no way to have it say, "set to turn on at 6am" unless you want to wake up before then, and set it up AT 6am. I would give this 5 stars if there was "memory" or even an on/off switch or some other setting to make it turn on when power is applied.

I had ordered something totally different at first as all these lights seemed to look much the same. When I realized the thing I first ordered was complete junk and would likely break I hit the Amazon catalog again. I found these that time. I already have thier shop lights in all my out buildings and they work great so I figured I would give these a try. They don't disappoint. They are way better quality than I expected. They came with everything you need to mount them in different scenarios. I just needed the zap straps. Lots there to do it too. Amazing freatures. I can see us growing year round with these in our small indoor garden without issues. I'll be sure to post a update if that changes.

I bought these for my wife’s indoor plants. I adhered them to the underside of shelves in two different cabinets, one wood and one glass. They are such a thin design they almost disappear. And my wife’s plants are looking wonderful.

I’m very happy with these lights. They are perfect for what I needed. I am big fan of this Barrina brand, they always deliver a quality product. I love that there is 3 light modes, I have success with this pink/white combo. I am happy that there is also a timer although I do wish there was the option to by pass this so I could use my smart plug to run it in sync with my other plant lights. Overall, they came well packaged, they give off very little heat and are super slim and take up very little space (which I loved). They were also super easy to install.

Easy to install in my Chyna cabinet turned Greenhouse. I get a little kick of endorphins every time the lights turn on in the am on their own and then off when the timer ends. And I’m not easy to please! JK I’m ordering more for my old bakers shelf to put the seedling I take from my cabinet and transplant to pots. I LOVE freaking love these lights! I spent a ton on lights tents etc during COVID and the answer would have been much simpler with this set up I’ve got now. Highly recommend growing your own food or keeping your plants alive in the cold darker winter months, with these lights .

My plants loveeeeeed this lights!! They are amazing! I’ll definetly buy more
