18W Plant Grow Light with Auto Turn On Function, slitinto Dual Head 36 LED 5 Dimmable Levels Grow Lamp Bulbs, 3/6/12H Timer, Spectrum Switching, Adjustable Gooseneck for Indoor Plants [New Converter]

I have a few grow lights that are similar to this one and this one has some notable improvements over them. I’ll address those first with a more general review afterwardsThe big one for me is that the timer function on this light doesn’t only turn off the lights after a certain number of hours but it then turns the light on again for the next 24 hour cycle. This is a great feature since the electronics of these lights prevent you from putting them on an external timer outlet. The UI is a little obscure: there is no way to adjust the turn-on time than when you first enabled the timer. In other words, if I want the light to turn on at 9am every day, then I need to first enable the timer at 9am. If it is currently 10am, there is no way to say the light should turn on at 9am. Additionally, the only indication that the timer is active at all is that the led blinks on the controller; there is no way to know when the light will turn on again. The internal clock also seems to drift a few minutes over several days of use. It is hard to measure exactly how much unless you’re standing around when the light turns on, but I estimate it drifted about 30-60 seconds per day. This can be reset by just disabling and re-enabling the timer. Despite all this, I find the feature useful and it keeps my plants happier than relying on me to turn the lights on every day.The other new feature is that you can choose which spectrum the light should operate in: red, blue, or both. I’ve read that some plants will react better in different stages of their lifecycle (e.g. flowering vs growing) with different lights but I don’t have any experience with this. It is nice to have the option to play with it, though.More generally, this light makes my plants much happier than they would be in my apartment which gets too little light for them. Within days of setting it up they had noticeable new growth and their leaves looked a bit lusher. There are two LED rods at the end of goosenecks that you can angle in different directions but they don’t twist so pointing in some directions is much harder. There is a clamp that should fit over about ½” I estimate. If you have tall plants you might want to attach the lamp to a different surface since it doesn’t have a ton of height.It is powered by USB and comes with a USB outlet adapter so you can plug it either into a wall outlet or a USB power source if that is easier.Overall I’m quite happy with the lamp and would recommend it to friends. I am giving it five stars because I think it is a good value and my primary issue with it–that the UI for the timer is a bit hard to use–would be hard to resolve, in my opinion, at this price point.

UPDATE...This seller was very quick to contact me and, they quickly sent me out a replacement product. The new USB wall block is bigger and works perfectly and the cords are overall a little more substantial with no shorts. Everything is working perfectly; my plants love these lights!ORIGINAL REVIEW....The USB power cube didn't work right from taking it out of the box. I had to use a similar one that I already had. When it works, the lights are powerful and my plants definitely are more vibrant, but it will often flicker and turn off like there's a short somewhere, then not turn back on right away. I had high hopes, but I'll be returning this.

Great grow light. Two arms that separate and can be set at endless angles to accommodate different plants. It arrived in perfect condition and much quicker than I expected. I especially love the timer on this unit. It can be set for 3,9, and 12 hours and works much like the battery operated candles...once they are turned on and set for the length of time needed on your plants, it turns on every day at that time. The lights can be adjusted from pink to blue depending on what you want. I am trying to get some seeds to sprout and I believe this unit may be just what I needed. I've attached some pictures if you can see them. I highly recommend this light. but it is difficult to photograph.

I purchased these to start my vegetable seeds and it works quite well. Setup is super easy - you plug it in (I needed to use an extension cord because the cord is rather short) and then press the button to turn it on, press the color changing button to change the light to pink, blue, or purple, and press the timer button to choose the on/off interval (once for 3 hours, twice for six hours, and three times for twelve hours),I've been using this about a month now on the purple setting with 12 hour intervals and it works well. I have the unit clipped to the side of a metal shelving unit (Amazon Basics brand) and I covered the sides and top/bottom of the shelf with foil so no light is wasted and it seems to be working. The plants seem to be enjoying it and are healthy and hardy. The light is a bit finicky and if the plug is jostled even the tiniest bit then you have to reset the timer which is annoying but has only happened a handful of times. The area covered is not huge (the shelf mine is on is about three feet wide), but it's plenty of area for starting seeds, especially with the foil reflecting the light back. Larger areas will probably need two units.Overall, this is easy to use, the timer function is a huge timesaver, and the plants are thriving so I certainly recommend it.

I purchased this item to grow some indoor plants. The light itself is very good. Bright but not hot. A soft blue or purplish red. The dual heads are adjustable and that's good to direct light in different places. I clipped mine to the table which was very convenient. Mine came and i had an issue with the timer. When i set it to 12 and turn it off, it would not allow me to press the button and turn it back on, and it did not turn back on after 12 hrs elapsed. Perhaps internal issues with the timer need readjusting. Overall its a good light but iffy timer.
