These lights are a success. In the fall and winter months, my plants can not survive with out grow lamps. I have a total of three units I use 4 to 6 hours each day in fall and winter.timer function very accurate and helps keep carny plants healthy.. you even can set morning, midday, and night color so you can simulate different lighting requirements cycles on it great little lampFound the correct adapter for it, works like a charmI managed to topple this lamp onto the floor, and it fell hard but still works just fine. The "necks" of the three lamps are easy to bend in whatever direction your plants require. I use the clamp by clipping it on the edge of a table and it is very sound. I haven't tried the timer yet because I really don't require it, but as of now I am very pleased with the solidity and quality of this product.Works well when braced upUpdated review: (Below was my original review) After having lights that failed after just a few weeks of use, the company sent me a new set of lights. The lights work well but since I got them toward the end of needing them for my spring seedlings, I won't really know how they last until next spring. However, the spot where the last lights failed was at the plug. The old lights used a USB type plug (where a USB cord plugs into a universal outlet plug). On the old lights, the spot where the USB plugged into the outlet plug is that spot that was disintegrating. The new lights use a normal cord to plug into the wall. So, the spot where the failure occurred is no longer an issue with the new lights. I don't foresee having the same issue with the new set of lights. The seller responded to the issue quickly and issued the new set of lights, despite the time between when I made my original purchase and when the equipment failure occurred.Old review:I bought these late in March of last year. One of the two sets of lights was not useable when I first made the purchase. The company replaced it for a new one. I was able to use the lights for my seed growing last spring. Even during those few weeks, I had trouble with the lights. Sometimes they would not turn on but they worked just barely long enough to use for a few weeks until my seedlings went outside. But now, I am trying to use them again for my spring seeds and they worked for about a day. Now, they are completely dead and one of the sets sparked when I plugged them in. I am completely disappointed. Not only did I waste money on these lights but now, my seedlings have to wait until the new lights that I ordered arrive.2nd update- the light originally said it came with 3, 6, and 9 hr timers but it’s 3, 6, 12 instead. Not a big deal to me, I prefer leaving the light on longer anyways. I’ve moved the light quite a few times and unplugged it etc but it’s still functioning correctly, no issues with it shorting out this time. So far I’ve been able to enjoy this replacement light. It originally took 2-3 months for the first one to show show it’s defects. If I notice any shorting out or defaults later I’ll update my review.Update- company has reached out to me to see if I wanted an upgraded light or a refund. I informed them I was already able to receive a full refund through Amazon’s extended Holiday return policy. Even after knowing that, they still have offered to send me an upgraded light for customer satisfaction. Online the light looks the same but I think I saw the timer only goes to 9 hrs instead of 12 hrs so I do believe it’s been upgraded or changed. I’ll take the replacement and update the review after I receive and use the light. For now it’ll get 4 stars but if the lamp works well and keeps working I’ll upgrade the review again. I’m glad to see they do care about customer satisfaction.Original review This worked great at first. I even recommended to my friends that they buy one. One did purchase one. We’ve had them since the end of October, her light broke and then two weeks later my light broke. Very disappointedUpdate-6/15/20I heard from the company and they offered a replacement or refund for this product. I received the replacement today and will use the lamp once the weather shifts to colder. I am hopeful the new lamp will work well. I thought it was important to post the company’s contact and concern. It was nice they reached out. That ups my original review. (6/17/20 - works well and I am very happy with Customer Service )Original Review- I loved this plant lamp when I first got it but unfortunately it had problems roughly two weeks after I started using it. It almost felt like there was a short in the wiring. Sometimes it would stay lit and other times it was a total dud. I'm so disappointed. When the troubles started, Covid 19 was just starting to make its way into our lives and I really didn't want to go to the Post Office so, I jiggled the wire and used the light as much as I could. It's been frustrating and disappointing but I kept using it because I have such low light in my home and wanted my plants to have a chance at thriving. Happy now that Spring has finally arrived and the plants are all on the back porch. I think this lamp is highly sensitive and not constructed with much durability....the lamps themselves seem super strong but the wiring and the control button are really of a lower standard. Not sure what I'll do this Fall and Winter because this lamp has gone out with yesterdays trash. Oh how I wanted it to work and to be able to write a good review. It did have a great light when it worked.Only just bought seems solidly built and decent quality but 2 pin power adapter is no use for UK Market so have changed it for one from my phone .This is not shown in any sales photos on Amazon
