Dimmable Wall Sconces: Each battery wall lamp offers 4 levels of color temperature (3000-6000k) and 5 levels of brightness (30-200lm), allowing you to choose the appropriate lighting for different scenes. Rechargeable & Battery Operated: Charging for 8-10 hours provides 15-20 hours of usage. We also specifically equipped the battery wall lights with an 80cm long Type-C charging cable, eliminating the hassle of battery replacement. Remote Control: You can control the status of the cordless wall lamps by remote control, making it easy to operate.
