BarrinaGrow Lights for Indoor Plants, Full Spectrum Sunlight, 2ft 40W (4 x 10W, 250W Equivalent), LED Grow Light Bulbs, T5 Grow Lights, Plug and Play, Pinkish White, 4-Pack

Love these lights so far! Easy to hang & comes with many options & supplies. Make sure to measure the space before buying if you plan on using the connectors bc they aren’t very long. Worked fine on my shelf where the shelves are 11.4 inches apart. Lights are bright and connect to a wall timer perfectly. Looking forward to seeing how they help my plants grow

I am using these lights on a shelving unit for grow lights.PROS: 1. Each light has a switch to turn on or off SEPARATE from the other lights. The feature is there according to your needs and preferences.2. I’m using them for AFRICAN VIOLETS and the Kelvins are perfect for them, or other indoor plants.3. Provided with the lights were 3 WAYS to secure them….including sticky tape, zip tie.4. The actual LUX of lights were CONSISTENT.5. An END CORD was provided to plug ALL the lights into ONE outlet.CONS: 1. The cords provided needed to be replaced because they were too short to reach the next shelf in my new larger shelf. The only way is if the shelves are close together, but even then, ITS NOT IDEAL to be pulling on the cord toreach another light on the next shelf.2. The sticky tape, double sided, failed and I would not use them to permanently secure the light. PLEASE DO NOT TRUST THEM TO PERMANENTLY FIX THE LIGHTS!! They will fall INTO YOUR PLANTS!!!I am using the ZIP TIES TO ENSURE they won’t fall again, which did damage to a beautiful plant.3. I had an added cost because the cords to daisy chain the lights were too short. To give you an idea, my shelves are 20” apart so can judge how it works for you according to the length of the cords.The lights themselves are EXCELLENT and do an excellent job of being grow lights, however, you CANT FORGET that the double sided tape is NOT secure, but the zip tie is. As long as you don’t mind using zip ties, and you are ok with possibly needing longer cords to connect the lights.I’d HIGHLY recommend this product because the lighting is EXCEPTIONAL for your indoor plants that don’t have a good window to put them in.BUY WITH CONFIDENCE!!!

I've been struggling to keep my indoor plants happy during the winter months, and these lights have been a complete game-changer.Here's why I'm giving them a solid 5 stars:Bright and Effective: The light output is fantastic. My plants, from succulents to leafy greens, have shown a noticeable increase in growth and vibrancy. They're no longer reaching for the limited sunlight from my windows.Easy Installation: Setting them up was a breeze. They're lightweight and the included mounting hardware made it simple to attach them under my shelves.Affordable: Compared to other grow lights on the market, the Barrina lights offer exceptional value for the price. They're a budget-friendly solution for anyone looking to boost their indoor gardening.Sleek and Unobtrusive: The design is clean and modern. They don't look bulky or out of place in my living space.Consistent Performance: I've been using them for several weeks now, and they've been consistently reliable. No flickering, no overheating, just steady, bright light.My plants are thriving, and I couldn't be happier with my purchase. If you're looking for a reliable and affordable grow light solution, I highly recommend Barrina!

The quality of the lights are good but be aware the extensions to link them together could be too short for some projects. (They reached between the shelves on my metal Amazon basic shelves, but not on my wooden bookshelf, for instance. Luckily they also offer different size extensions separately. These lights are perfect for keeping all the plants on my shelves healthy. For fruiting vegetables you would probably need something more powerful but these are good lights for maintaining and presenting the majority of indoor plants.

A good deal for small mountable lights for your plant table terrarium etc.

I purchased three sets of these lights to create a four-level seed-starting setup, and overall, I’m quite pleased with their performance. One of the most impressive aspects is the accuracy of the PAR values—after testing with a highly reliable and calibrated PAR meter, I found the manufacturer's claims to be spot on at the specified 7.78” height.Since I’m growing vegetable and herb seedlings, I aimed for a PAR range of 150-300. This required some adjustments in light spacing and height to achieve optimal results. Below are some key findings from my testing:- Two lights spaced 7.87” apart at 7.87” height: Consistent PAR readings around 104.- Two lights at 2.5” height: PAR values reached approximately 233 directly below each light but dropped off sharply in between (around 85 PAR).- Three lights spaced ~4” apart at 2.5” height: More even coverage with PAR values ranging from 280-320.- A single light at 2.5” height: Provided ~229 PAR directly underneath but dropped off significantly (95 PAR at 2.5” away, 19 PAR at 5” away).These results indicate that spacing and the number of lights used will significantly impact the effectiveness of the setup. For a 2-foot by 10-inch growing area, I’d recommend using three lights, spaced about 4” apart and positioned about 3” above the plants to achieve a balanced light distribution.One minor drawback is that I wish an extra connecting wire had been included, which would have made the setup more convenient. However, this is a small issue compared to the overall quality and performance of the lights.If you're setting up a grow station, carefully consider the PAR values and spacing to ensure your seedlings get the optimal light exposure. Be sure to check out the attached diagram for a detailed breakdown of my findings.
