All components (excluding 2 gang socket) required to build your own Emergency Safety Socket.
The appliance operates similarly to the existing socket until it detects the power is removed when it automatically switches to battery operation and illuminates the bright light emitting diodes.
The rechargeable battery enables the light emitting diodes to stay on independently for up to a minimum of three hours or until the electrical power returns.
