The Aurora Radio Control System is an add on to the CIRLS which is a modular system consisting of battery box paired with one of their light heads. The CIRLS allows use of AA or CR123A batteries in the same box.
Aurora fits between the battery box and the light. It offers a 2-mile range using mesh technology and will control up to 99 beacons via 10 channels.
Due to the use of their 3-prong connection, you can use Aurora to upgrade any existing CIRLS unit.
