The Aesthetics of Wood: These bedroom wall lamps are distilled to their purest form, precision CNC machined from a carefully selected piece of solid wood and hand-finished to achieve a beautiful smoothness, highlighting the natural grain of the wood with meticulous attention to proportions. 4000mAh Battery: The wireless adjustable wall lamp features a 4000mAh rechargeable battery with a fast-charging USB Type-C port. A full charge takes 3 hours and provides 7 hours of light (highest brightness) to 30 hours (lowest brightness). 360° Rotation & Portability: The rotating magnetic ball design allows the rechargeable LED adhesive lamp to rotate 360° to adjust the light angle and securely lock it in place. Stepless Dimming & Memory: The bedroom bedside lamp is controlled by a touch switch. Press and hold for stepless dimming from 10% to 100%, and it will remember its last setting when activated again. You can use it in any room, such as the bedroom, office, living room, or children's room in the house. No Drilling Required: You can easily install the wireless wall-mounted reading lamp with the included strong adhesive strip or screws, as needed.
