shall be operated at the appropriate voltage and current conditions
as described in ANSI C78.375 (incorporated by reference; see §

or ANSI C78.901 (incorporated by reference; see § 430.3), and lamps
shall be operated using the appropriate reference ballast at input
voltage specified by the reference circuit as described in ANSI
C82.3 (incorporated by reference; see § 430.3). If, for a lamp,
both low-frequency and high-frequency reference ballast settings
are included in ANSI C78.81 or ANSI C78.901, the lamp shall be
operated using the low-frequency reference ballast.
4.1.2 For lamps not listed in ANSI C78.81 (incorporated by
reference; see § 430.3) nor in ANSI C78.901 (incorporated by
reference; see § 430.3), the lamp shall be operated using the
following reference ballast settings:
4.1.2.1 4-Foot medium bi-pin lamps shall be operated using the
following reference ballast settings: T10 or T12 lamps are to use
236 volts, 0.43 amps, and 439 ohms; T8 lamps are to use 300 volts,
0.265 amps, and 910 ohms.
4.1.2.2 2-Foot U-shaped lamps shall be operated using the
following reference ballast settings: T12 lamps are to use 236
volts, 0.430 amps, and 439 ohms; T8 lamps are to use 300 volts,
0.265 amps, and 910 ohms.
4.1.2.3 8-foot slimline lamps shall be operated using the
following reference ballast settings:

of the measured lamp lumen output and lamp electrical power input
at equilibrium for the reference condition.

LM-45.
4.2.3 The measurement procedure for testing the lifetime of
general service incandescent lamps shall be as described in IESNA
LM-49 (incorporated by reference; see § 430.3). The lifetime
measurement shall be taken by measuring the operating time of a
lamp, expressed in hours, not including any off time. The
percentage of the sample size that meets the minimum rated lifetime
shall be recorded. The lamp shall be deemed to meet minimum rated
lifetime standards if greater than 50 percent of the sample size
specified in § 429.27 meets the minimum rated lifetime.

paragraph of section 6.1 of IESNA LM-49 is to be disregarded.

reference condition in accordance with § 7.2 of IESNA LM-20
(incorporated by reference; see § 430.3) or from an average
intensity distribution curve measured at the reference condition
specified in § 6.0 of IESNA LM-20. Lamp electrical power input in
watts shall be measured and recorded.
4.3.3 Lamp efficacy shall be determined by computing the ratio
of the measured lamp lumen output and lamp electrical power input

reference; see § 430.3) and rounded to the nearest 10 kelvin for
general service fluorescent lamps. The CCT shall be determined in
accordance with the CIE 15 (incorporated by reference; see § 430.3)
for incandescent lamps. The required spectroradiometric measurement
and characterization shall be conducted in accordance with the
methods set forth in IESNA LM-58 (incorporated by reference; see §
430.3).
