A Wireless IKEA Lamp

The lamp is of the LED variety using an Edison screw fitting (the live connector is found at the tip of the bulb while the neutral connector is the screw fitting, itself). One advantage of the Edison screw fitting is that the screw fitting on the lamp holder is connected to neutral which means that (in theory) if the system was live and someone was to put their hand into the bulb holder they will not be electrocuted unless they push their finger right to the base where the live contact is found.
