When Cirque Du Soleil decided to do a new show in Las Vegas at the Luxor Hotel and Casino they contacted Sigma to get a custom flame system designed and installed. As with all Cirque shows, it promised to be spectacular in its design and complexity. After months of planning and work R.U.N. opened at the Luxor theater with all of the spectacle people have come to expect from a Las Vegas night show. Sigma decided to use custom versions of the Prometheus Flame System to accomplish the effects desired providing a resilient and new age flame unit to help meet stringent Vegas requirements for safety and reliability.
