These lights fit perfectly in my Ikea greenhouse that I made! They were easy to instal and are the perfect brightness for my plants.

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

After getting sick of cheap grow lights with the built in digital timer/dimmer switches breaking, I opted for these with the manual on/off switches. I have them plugged into separate mechanical timers so they’re more reliable and versatile. These lights seem to be good quality, and at a good price. We’ll see how long they last and if my plants like them, but I love how many different configurations there can be with all the supplies included. They’re super easy to install and they emit a natural cool-white sunlight tone. Simple sleek design, less stuff to break, and allows for flexibility with your light set up needs.

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 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.
