Originally launched at InfoComm 2011 in Orlando, AMX Light Control by Lutron system uses the existing electrical infrastructure, so no new wires need to be installed. The wireless solution gives installers a quick path to add light control and occupancy sensing to a smart-room automation solution with AV control including features like scheduled shutdowns and energy management. Additionally, by removing the limitations related to pulling new wires, light control can be offered in virtually any location — ideal for retrofit installations.
