Advanced CMH Electronic Ballast, Dimmable, Multi-Lamp

This study characterizes the lighting performance of bi-level ceramic metal halide (CMH) area lighting fixtures for substation uplight duty, and quantifies the energy savings potential when compared to conventional pulse start metal halide (PSMH) area fixtures. This market subset of the general outdoor lighting market was chosen to meet jointly the specific market and application of lighting electric substation switchracks for safety, i.e., workers operating switches typically 7- to 12-feet AFG and for walkabout in those zones.
