Review on 🌈 Enhance Your Space with AISITIN Puck Lights Battery Operated Lights – Remote Control, 8 Pack Under Cabinet Light with 16 Colors & 3 Modes (6000K/4000K/RGB), Includes 2 USB Cables by Chris Horton

White backlight can be different, some are bright, some are soft. If you use more than one, make sure you check your light sources to make sure they are symmetrical. I used them for handmade wall lights and the brightness had to be the same in both washers. I had to try them all to find a match and found that there were four bright whites and four soft whites. USB does not charge flashlights, they must remain connected to USB to work. The battery compartment is very cheap, the springs are flimsy, but it does the job. If all you need is lighting and you have a large supply of AAA batteries on deck, this product will do.
