The same PG Series fixtures were installed in the school's labs. Initial illumination levels measured on lab benches were 112 footcandles. Although the PG Series fixtures are more costly to purchase initially, the school will save money in the long term because the system includes fewer fixtures and consumes less energy. An occupancy sensor with a key-operated override switch controls lighting fixtures in each room. This allows teachers to turn off the fixtures during videos or other presentations.
Lamps are spot re-lamped as needed, with fixtures scheduled for cleaning during summer break.
