Energy efficiency of high-intensity discharge (HID) and low-pressure sodium (LPS) lamp ballasts

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.

Note: Safety requirements for ballasts are provided in Part 2 of CAN/CSA-C22.2 No. 74.

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.

1.6 In CSA standards, "shall" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; "should" is used to express a recommendation or that which is advised but not required; and "may" is used to express an option or that which is permissible within the limits of the standard.

Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.

Notes to tables and figures are considered part of the table or figure and may be written as requirements.

Annexes are designated normative (mandatory) or informative (nonmandatory) to define their application.

1.7 The values given in SI units are the units of record for the purposes of this Standard. The values given in parentheses are for information and comparison only.
