Abstract
A lighting system is disclosed wherein each fixture in the lighting system includes a permanently attached radio frequency identification (RFID) tag. Each fixture also includes either a matching hardwired identification chip or an RFID reader capable of reading the RFID tag. The tags can be used for commissioning the lighting system by reading the tags with a portable reader and assigning or removing fixtures from groups. The tags can also be used for other tasks requiring identification and tracking of specific fixtures.
