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