Term used to describe a generic lighting rig. Usually consists of two 40' trusses of 5 @8' sections of PRT, each containing 2 @6-lamp par-bars for a total of 60 lamps per truss, 120 total. Most often the DS lamps are 1kPAR64-MFL, and the rear lamps 1kPAR64-NSP. Add 4-6 ACL banks on the US truss, and 4-6 ERSs on the DS as specials.
Even when the fixtures are 575 or 750W Source Four PARs, it's still called a 120K rig.
Control can be 120 1000W dimmers, or a minimum of 60 2.4kW dimmers. Moving lights are optional.
