scope:

This Standard describes testing procedures and states performance requirements for general service incandescent and tungsten halogen reflector lamps.

This Standard includes performance requirements for

(a) wattage;

(b) lamp efficacy;

(c) rated luminous flux;

(d) centre beam intensity; and

(e) rated life.

This Standard applies to incandescent and tungsten halogen reflector lamps designed for general lighting use that have

(a) a rated wattage from 40 W up to and including 205 W;

(b) an operating capability between 110 and 130 V;

(c) an E26/24 single contact, or E26/50×39 skirted, medium screw base; and

(d) a bulb diameter greater than 57 mm.

This Standard does not apply to any of the following:

(a) coloured lamps;

(b) lamps that

(i) are of rough (or vibration) service type and are specifically marked and marketed as rough (or vibration) service lamps;

(ii) have a coating or other containment system to retain glass fragments if the lamp is shattered and are specifically marked and marketed as impact-resistant lamps; or

(iii) contain a filter that suppresses yellow and green portions of the spectrum and are specifically marked and marketed for plant growth use;

(c) infrared heat lamps;

(d) lamps used in mines or in airfield, aircraft, automotive, marine, aquarium, terrarium, or vivarium applications;

(e) a bulb shape designated as BR as described in NEMA/ANSI C79.1 with

(i) a diameter of 95.25 mm (BR 30) and a rated power of less than or equal to 50 W;

(ii) a diameter of 95.25 mm (BR 30) and a rated power of 65 W;

(iii) a diameter of 127 mm (BR 40) and a rated power of less than or equal to 50 W; or

(iv) a diameter of 127 mm (BR 40) and a rated power of 65 W;

(f) a bulb shape designated as ER as described in NEMA/ANSI C79.1 with

(i) a diameter of 95.25 mm (ER 30) and a rated power of less than or equal to 50 W;

(ii) a diameter of 127 mm (ER 40) and a rated power of less than or equal to 50 W; or

(iii) a diameter of 127 mm (ER 40) and a rated power of 65 W;

(g) a bulb shape designated as R as described in NEMA/ANSI C79.1 with a diameter of 63.5 mm (R 20) and a rated power of less than or equal to 45 W;

(h) bowl mirror lamps (e.g., silverbowl); or

(i) lamps for heat-sensitive applications (i.e., dichroic cool beam).

In this Standard, "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.
