Outline
• Solid State Lighting Standards
• ENERGY STAR Program Requirements
• New ENERGY STAR Qualification Process

2011-12 International Objectives
• Engaged with partner countries on US
ENERGY STAR efforts with enhanced testing
and verification
• Enhance existing ENERGY STAR relationships
– substantively contributing to high-profile
international energy efficiency projects.
– sharing successful approaches and best
practices.

• Continue to pursue test procedure
harmonization
– providing in-depth coordination with countries
that are developing new/revised product
standards.

SSL Test Procedures: Light Output

• IESNA LM-79-2008
– Specifies a standard test method
for measuring the photometric
properties of SSL devices,
allowing calculation of luminaire
efficacy

Maintenance
• IESNA LM-80-2008
– Specifies a standard method

SSL Test Procedures: IES TM-21-11: Projecting
Long Term Lumen Maintenance of LED Sources
• For ENERGY STAR qualification,
lumen maintenance projections using
LM-80 data will be based on IES TM21-11
• Covers LED packages, arrays,
modules
• Sample size recommendation
adopted by EPA (LM-80 is silent
about sample size)
• Finalized in August, available to labs
in September

SSL Standards: Color
• ANSI C78.377-2008 - Specifications for the Chromaticity of SolidState Lighting Products (2012 revision pending)
• Specifies the recommended chromaticity (color) ranges for white light
LEDs with various correlated color temperatures (CCTs)

SSL Test Procedures : IES LM-82-11 for
LED Light Engines
• IES LM-82-11 (in draft):
Approved Method for the
Characterization of LED Light
Engines and Integrated LED
Lamps for Electrical and
Photometric Properties as a
Function of Temperature
– Normative reference:
IES LM-79-08 for photometric
and electrical measurements

ENERGY STAR Program Requirements

ENERGY STAR Luminaires, Version 1.1
• Combining the existing
Residential Light Fixture and
Solid State Lighting
specifications
• Technology neutral
• Divided lighting into Directional
and Non-Directional categories
• Specification final: effective
date in April 1, 2012

ENERGY STAR Integral LED Lamps
• Effective date of August 31,
2010.
• Includes:





general service (A Line)
decorative
(candelabra style)
reflector lamps

• List of qualified products:
www.energystar.gov/lightbulbs

ENERGY STAR CFLs
• V4.0 finalized in March,
2008
– (Latest version 4.3, October
2011)

• Latest criteria covers the
following:
– Medium (Edison) screw
based: covered, uncovered
and reflector. GU24
– Candelabra screw based:
covered and uncovered

• List of qualified products:
www.energystar.gov/lightbulbs

Coming Soon –ENERGY STAR
Lamps Specification
• Will combine the existing Compact
Fluorescent Lamp and Integral
LED Lamp specifications
• Technology neutral where possible
• First draft to be released +October 12, 2011

Test Procedure –LED Outdoor Lighting
• NEMA/DOE Taskforce currently developing a power
density metric that seeks to relate quality lighting, as
established by IES Standards (RP-20 and RP-8), to
power consumption in real world applications
• In process; timeline is TBD

The Importance of Monitoring and
Verification
• DOE Caliper Program
– SSL products
– Widespread false claims found

• EPA Testing
– Residential Light Fixture and
Solid State Lighting Luminaires
– Problems with lumen
maintenance for lamps

• EPA Testing - CFL
– Problems with run up time, rapid
cycle testing

Enhanced Testing and Verification
Information
• For more information on ENERGY STAR’ new
s
Testing and Verification Requirements, see:
www.energystar.gov/testingandverification

Summary
• Standards and test procedures are essential for SSL due
to its rapid development
• ENERGY STAR is relying on standards and test
procedures to ensure quality products
• Standards by themselves are not enough: as shown in
the USA, monitoring and verification is essential
• EPA is interested in regional and international
cooperation on harmonization of test
procedures/standards
