CSA C863-04

1.1 This Standard applies to ballasts for high-intensity discharge (HID) and low-pressure sodium (LPS) lamps. The HID category includes mercury vapour, metal halide, and high-pressure sodium lamps.

1.2 This Standard defines the measurement technique for determining the efficiency of HID and LPS lamp ballasts for use in HID and LPS luminaires that are to be installed in industrial, commercial, or residential locations.

1.3 This Standard defines minimum energy efficiency levels for HID and LPS lamp ballasts. Note: Power factor is also an important energy management consideration, but is not within the scope of this energy efficiency definition.

1.4 This Standard applies to HID and LPS lamp ballasts intended to operate at input voltages of 120, 208, 240, 277, 347, 480, and 600 V nominal and at a line frequency of 60 Hz.

1.5 This Standard does not apply to (a) ballasts specifically marked and marketed for stage and studio applications; and (b) ballasts specifically marked and marketed for medical equipment.
