Review on 🔧 Honbay 100-Pack Black Plastic 5mm LED Mounting Holders for Panel LED Light Fixation by Delos Rodeo

I've been using this type of bracket for LEDs for over 40 years. (Yes, they weren't designed last month.) All of the ones I've used before have a retaining ring that snaps onto the back to allow for different board thicknesses. Rings are missing from these and all similar elements. I found on Revain. For thin panels, the lack of a retaining ring makes them almost useless unless you get your hot glue gun out (dirty).
