The Unplugged 2775 AC Adapter connects to the DC input port on the back of Unplugged LED500 lights and provides continuous power to the light from a household wall socket.
It may be connected to the light at the same time a 6817 Unplugged battery is also installed. The 3-part power switch on the LED500 allows you to select power from the battery or AC source in this situation.
Note: this AC power supply will run the LED light continously. However, it will NOT charge the battery. Use the Unplugged battery charger (6922) included with the light for charging purposes.
