Review on 🔆 Moobibear Under Cabinet Lighting Kit - 6 Pack of Dimmable Warm White LED Puck Lights, 1800lm, 3W, Perfect for Kitchen, Closet, Bookshelf - Plug in Under Cabinet LED Light by Ashley Collins

At first I couldn't figure out how to separate the washer from the base - I tried to unscrew or loosen it somehow. The instructions were very vague on this. In the end it turned out that if you pull hard enough you could overcome the small spring shape putting pressure on the inner "washer" to keep it in the mounting base. Once that was achieved it was a very simple setup. These lights have quite a long cord length, so you can mount them almost anywhere as long as you're willing to tie or hide the cords. Dimming works as it should. Haven't used it long enough to comment on life expectancy but meets my expectations for now. Used them in a rack project.
