Lighting accounts for approximately 30% of overall electricity use and demand in commercial buildings. In recent years,
many high-efficiency lighting technologies have been developed that offer significant energy savings without
compromising lighting quality.

In fact, lighting quality can often be improved by proper application of new, energyefficient
lighting technologies. However, the market penetration of these technologies has been slow, due in part to the
lack of readily available information. To assist their customers in using lighting energy efficiently, utility personnel need
to understand the fundamentals of lighting principles and technology. In 1986, EPRI published a basic lighting reference,
the “Lighting Handbook for Utilities” (report EM-4423). This “Lighting Fundamentals Handbook” is intended to serve as
an updated and improved reference for utility personnel.
