Update 20Feb2025: The light lasted almost 6 months before dying (completely dead) on the first complete charge for my application. Not bad. Everything is still well stuck, nothing has fallen off. I have since mounted one each of these in a couple of Ikea PAX wardrobe cabinets and they work great in that application to provide just enough to see what is going on in a dark or dim environment in our bedroom. Product purchased was the 13-inch, white, two pack. I would definitely buy these again if needed. I was surprised, when I measured this light, that it exceeds its specs. It is pretty rare, in my experience, with battery operated products to do so on Amazon. I fully charged one light. Then let it run at its brightest setting until it died. It lasted a total of 11 hours and 6 minutes. Then I charged it to full from that state. It took 5 hours and 6 minutes. Total capacity to charge was 3325mAh. I'd say that for the first 9 hours or so it was at the full bright setting and at about the 9 hour mark it dimmed to about the 50% setting (still very usable in my corner cabinet use case) for the last two hours before shutting down completely. When the light is activated by motion, it stays on for about 20 seconds. It stays on longer if motion keeps triggering it until the motion stops. The light measures 13 1/16 inches long and 1 3/4 inches wide and using the sticky magnetic plates for mounting, the total thickness is 1/2 inch (about 7/16 inches without the metal plate). The two metal plates that you stick to your surface are 2 5/16 by 1 inches. There is pretty small hole in the metal plate that you could theoretically use to mount with a screw but the metal is pretty thin and the hole is only 1/6 inch wide but could be very easily drilled out wider if needed. Since it is so thin, you would definitely need a flat head screw to try and get the screw head flush with the plate. You could always use a similar or smaller sized plate of your own making as well. The plate is not a magnet, just magnetic. The magnets are within the light spaced about 9.5 inches apart, so you can stick these on magnetic surfaces which opens up all kinds of other applications for these). A couple of flat head screw heads or washers were all it took to support the light's weight horizontally, but they would not do so vertically as the light's back surface is metal (aluminum it seems) and so it slides off the screw heads in that position. I've mounted one each of these vertically in two corner cabinets. So far everything is staying stuck pretty well. Will report back if/when they fall off/unstick. Photos show a USB meter while charging (red light) and when fully charged (green light). The motion sensor bubble lights red while charging and green when complete. Two other phots show the inside of the cabinet during daytime, one with light off and the other with light on. I adjusted the photos' brightness to match what I see with my eyes, to give a realistic representation of before and after brightness levels. Light is mounted vertically on the right wall as shown in last photo (not adjusted for perceived brightness). One 8 inch USB-A to USB-C cable is included that has two USB-C connectors so you could charge two lights at a time. No power adapter is supplied. There are four switch settings: On (always on), Off (always off), Moon Symbol (only motion activates in dark environments) and a Sun symbol (motion activation active even in iight environments). Another button controls brightness levels a quick press cycles to the next brightness level. Brightness levels are stated as 100%, 75% and 50%. There is a fourth level that seems to be a duplication of the 50% level. Not sure what that is supposed to be. I could not get the Night mode to work. Even when shining a bright LED flashlight at the motion sensor, it still motion activated, duplicating the behavior of the Daylight setting (which is what I use in my cabinets). All 4 of my lights behaved the same way, so I doubt this is just a defect. You can also set the light brightness by pressing and holding the brightness button and releasing at the desired brightness level from 10% to 100%. The light will remember your brightness setting.
