Red Mountain High School completed a Red Mountain High School auditorium retrofit in 2016 that kept the existing auditorium layout while moving the space to LED retrofit technology. The auditorium is used by Dance, Theatre, Orchestra, Band, Choir, and Guitar programs, so the houselights see heavy use throughout the school year.
The school retrofit approach preserved the existing fixtures and infrastructure and focused on the benefits of LED retrofits: fewer lamp changes, improved maintenance access, and a consistent houselight wash for performances and assemblies. In this project Canto USA supplied RETRO-Classic houselights and Clearwing Systems Integration handled system coordination.
Working With Clearwing Systems Integration

The school worked with Clearwing Systems Integration on the project. Clearwing later coordinated additional retrofit work for Mesa Public Schools, including installations at Dobson High School and Westwood High School.
Red Mountain used two RETRO-Classic® models in the auditorium: 56 RETRO-Classic 500 units and 42 RETRO-Classic 300 units, all specified at 3000K. Using two output levels provided flexibility to address varying fixture locations and throw distances across the room.
Creating a More Even Auditorium Wash
The finished installation produced a more even houselight wash across the main auditorium and both side pods. Consistent houselighting improves the audience experience during entry, intermission, and exit and provides predictable illumination for rehearsals and performances.
Because many houselight fixtures are mounted high above the auditorium floor, routine lamp changes previously required lifts or special access equipment. The LED retrofit reduced the frequency of those service interventions while keeping the existing infrastructure intact.

Why this retrofit approach matters
- Preserves existing fixtures and layout, reducing scope and disruption.
- Improves maintenance cycles by reducing lamp-change frequency.
- Provides a more uniform auditorium wash appropriate for concerts, theater, and assemblies.
Keeping the retrofit targeted to houselights allowed the team to focus on these practical benefits without converting the entire lighting system.

Canto USA’s RETRO Series Fully Dimmable LED Retrofit Houselights
Canto USA is proud to present our RETRO series. The RETRO-Fusion® 2.0 and RETRO-Passive® 2.0 are 0-100% phase dimmable (forward and reverse) variable wattage LED 2700K-6500K 80-97 CRI engines. They are designed for older SCR, TRIAC, and IGBT dimmer systems but are compatible with newer dimmer systems.
A direct replacement of existing lamps, our LED retrofit can be used in a wide range of applications or even new installations. Custom and standard mounting options are available.
