LED wall lamp Boing with shelf and USB charging option Boing is the perfect wall lamp for the bedroom next to the bed. The universal white LED light can be swivelled and can be switched on or off via a toggle switch above the frame of the lamp. The diffuser disc provides even, glare-free lighting. The shelf can be used for the mobile phone and can even be charged by means of a USB cable (not included), because there is a corresponding USB slot (2A connection) underneath the light.
