At a number of the schools, the lighting fixtures that are around 20-35 years old have 2-4 fluorescent lamps where each lamp consumes 28-32 Watts each. Lighting fixture technology is continuously improving. The District has recently started to replace the lighting fixtures that can provide the same lighting output as the original fixtures but uses half the number of lamps.
The school district is in the process of replacing the outdoor perimeter and parking lot light fixtures with efficient fixture that use induction technology. This type of lighting will last longer than the conventional existing metal halide lighting. The new fixtures that are being installed uses 30 to 50% less energy than the existing fixtures. The induction technology also provides light with a wider spectrum where it has improved colour rendering than the existing fixtures.
