Local maintenance staff were able to save an additional 24% energy cost by simply replacing all lamps with Phillips 25 watt, high-phosphor T8 lamps. Before lamp replacement we found the clinic to be fairly poorly lit because a good share of the original T8 lamps were burned out. Ceiling height was not beyond 8’ and with all new 25 watt T8s light levels increased throughout the clinic following lamp replacement.
