★ Operation confirmed! ★ This is a daylight (white) LED light. ★ It's square, so you can also place it on a surface! ★ I was using it near the entrance of my bedroom. It was very convenient because I could set it up anywhere, but I'm selling it because I bought a different product. ★ To make it easier to attach, I've attached magnets purchased from Daiso to the back! ★ The battery cover was very difficult to open, so I've put tape on it and written how to open it with a pen. *The tape can be removed cleanly.
