Determining Load Characteristics
Lighting
For all types of lighting loads:
RkW = The sum of the rated watts of all lamps and ballasts.
Typical ballast wattages are defined by Table 2 below:

For all types of lighting loads, except for high intensity
discharge (HID), use the following:
discharge (HID), use the following:
SkW = RkW
Due to the starting characteristics of HID lighting, assume
that
that
SkW = 0.75 x RkW
Unless otherwise known, assume the following starting and
running power factors (SPF and RPF, respectively, see Table
3 below) for the following types of lighting:
