Appendix BB to Subpart B of Part 430 - Uniform Test Method for
Measuring the Input Power, Lumen Output, Lamp Efficacy, Correlated
Color Temperature (CCT), Color Rendering Index (CRI), Power Factor,
Time to Failure, and Standby Mode Power of Integrated
Light-Emitting Diode (LED) Lamps Note:
On or after March 20, 2019, any representations made with
respect to the energy use or efficiency of integrated
light-emitting diode lamps must be made in accordance with the
results of testing pursuant to this appendix.
1. Scope: This appendix specifies the test methods
required to measure input power, lumen output, lamp efficacy, CCT,
CRI, power factor, time to failure, and standby mode power for
integrated LED lamps.
2. Definitions
2.1. The definitions specified in section 1.3 of IES LM-79-08
except section 1.3(f) (incorporated by reference; see § 430.3)
apply.
2.2. Initial lumen output means the measured lumen output
after the lamp is initially energized and stabilized using the
stabilization procedures in section 3 of this appendix.
2.3. Interval lumen output means the measured lumen
output at constant intervals after the initial lumen output
measurement in accordance with section 4 of this appendix.
2.4. Rated input voltage means the voltage(s) marked on
the lamp as the intended operating voltage. If not marked on the
lamp, assume 120 V.
2.5. Test duration means the operating time of the LED
lamp after the initial lumen output measurement and before, during,
and including the final lumen output measurement, in units of
hours.
2.6. Time to failure means the time elapsed between the
initial lumen output measurement and the point at which the lamp
reaches 70 percent lumen maintenance as measured in section 4 of
this appendix.
3. Active Mode Test Method for Determining Lumen Output, Input
Power, CCT, CRI, Power Factor, and Lamp Efficacy
In cases where there is a conflict, the language of the test
procedure in this appendix takes precedence over IES LM-79-08
(incorporated by reference; see § 430.3).
3.1. Test Conditions and Setup
3.1.1. Establish the ambient conditions, power supply,
electrical settings, and instrumentation in accordance with the
specifications in sections 2.0, 3.0, 7.0, and 8.0 of IES LM-79-08
(incorporated by reference; see § 430.3), respectively.
3.1.2. Position an equal number of integrated LED lamps in the
base-up and base-down orientations throughout testing; if the
position is restricted by the manufacturer, test units in the
manufacturer-specified position.
3.1.3. Operate the integrated LED lamp at the rated voltage
throughout testing. For an integrated LED lamp with multiple rated

integrated LED lamp with multiple rated voltages is not rated for
120 volts, operate the lamp at the highest rated input voltage.
Additional tests may be conducted at other rated voltages.
3.1.4. Operate the lamp at the maximum input power. If multiple
modes occur at the same maximum input power (such as variable CCT
or CRI), the manufacturer can select any of these modes for
testing; however, all measurements described in sections 3 and 4 of
this appendix must be taken at the same selected mode. The test
report must indicate which mode was selected for testing and
include detail such that another laboratory could operate the lamp
in the same mode.

measured input power by the product of the measured input voltage
and measured input current.

lamp failures that result in complete loss of light output, time to
failure is equal to the previously recorded lumen output
measurement (at a shorter test duration) where the lumen
maintenance is greater than or equal to 0.7.
4.6.3. For lumen maintenance values equal to 0.7, time to
failure is equal to the test duration.
4.6.4. For lumen maintenance values greater than 0.7, use the
following method:
4.6.4.1. For test duration values less than 3,000 hours, do not

in this section 5 may be completed before or after the active mode
test method for determining lumen output, input power, CCT, CRI,
power factor, and lamp efficacy in section 3 of this appendix. The
standby mode test method in this section 5 must be completed before
the active mode test method for determining time to failure in

language of the test procedure in this appendix takes precedence
over IES LM-79 (incorporated by reference; see § 430.3) and IEC

this appendix apply to this section.
5.2.2. Connect the integrated LED lamp to the
manufacturer-specified wireless control network (if applicable) and
configure the integrated LED lamp in standby mode by sending a
