One
of the most common mistakes made in **Non-Residential **lighting compliance
is in calculating the wattage for medium base incandescent lights (screw-in
type fixtures). To calculate the wattage for medium base fixtures, two
values need to be compared: (a) the total lamp wattage proposed for the
fixture, and (b) 75 watts per fixture. The wattage used in the
calculation of **Actual Lighting Power** must be the __larger__ of these
two values. *(Standards Section 5.2.4-B.2)*
