A product must meet all the criteria in order to be qualified as ENERGY STAR. The ENERGY STAR criteria cover the requirements for SSL products used for general illumination, including those with significant decorative function. If a decorative SSL product serves a significant general illumination function, it falls within the scope of these criteria. The criteria apply to both residential and commercial products. The criteria apply only to products designed to be connected to the electric power grid. In addition, they do not apply to SSL products made for indication (such as traffic lights and exit signs); to products exclusively intended for decoration (such as holiday lights); nor to SSL products intended for retrofit into existing fixtures. The criteria are based upon compliance with existing lighting industry reference standards and test procedures, as well as new or revised standards and test procedures currently being developed by lighting industry organizations. These reference standards and test procedures are listed in the appendix. The following general requirements apply to both Categories A and B. Additional requirements for correlated color temperature (CCT), luminaire efficacy, zonal lumen density, and minimum light output are listed under Categories A and B below. ENERGY STAR Program Requirements for SSL Luminaires - Version 1.3 Scope General Requirements ------- All Luminaires Luminaire Requirements: Correlated Color Temperature (OCT) The luminaire must have one of the following designated CCTs and fall within the 7-step chromaticity quadrangles as defined in the Appendix. Nominal CCT(1) CCT (K> 2700 K 2725 ± 145 3000 K 3045 ± 175 3500 K 3465 ± 245 4000 K 3985 ± 275 4500 K 4503 ± 243 5000 K 5028 ±283 5700 K 5665 ± 355 6500 K 6530 ±510 Color Spatial Uniformity The variation of chromaticity in different directions (i.e., with a change in viewing angle) shall be within 0.004 from the weighted average point on the CIE 1976 (u',v') diagram. Color Maintenance The change of chromaticity over the lifetime of the product shall be within 0.007 on the CIE 1976 (u',v') diagram. Color Rendering Index (CRI) Indoor luminaires shall have a minimum CRI of 75. Off-state Power Luminaires shall not draw power in the off state. Exception: Luminaires with integral occupancy, motion, photo-controls or individually addressable fixtures with external control and intelligence are exempt from this requirement. The power draw for such luminaires shall not exceed 0.5 watts when in the off state. Warranty A warranty must be provided for luminaires, covering repair or replacement of defective electrical parts (including light source and power supplies) for a minimum of three (3) years from the date of purchase. For residential products, the written warranty must be included with the luminaire packaging at the time of shipment. Thermal Management Luminaire manufacturers shall adhere to device manufacturer guidelines, certification programs, and test procedures for thermal management. (1) Six of the eight allowed nominal CCTs correspond to those in the fluorescent lamp specification: 2700 K, 3000 K, 3500 K, 4100 K, 5000 K, and 6500 K. ENERGY STAR Program Requirements for SSL Luminaires - Version 1.3 ------- Modules/Arrays Package/Module/Array Requirements Lumen Maintenance of LED Light Sources (L70) LED package(s)/module(s)/array(s) used in qualified luminaires shall deliver at least 70% of initial lumens, when installed in-situ, for the minimum number of hours specified below: Residential Indoor: 25,000 hours Residential Outdoor: 35,000 hours All Commercial: 35,000 hours Outdoor Luminaires Outdoor Luminaire Requirements Residential Automatic Daylight Control Residential luminaires designed for attaching to buildings and whose power consumption is greater than 13 watts must contain an integral photo-sensor that automatically prevents operation during daylight hours. In addition, the control must automatically reactivate within 24 hours of a manual override or test operation. Power Supplies Power Supply Requirements Power Factor Residential > 0.70 Commercial > 0.90 Minimum Operating Temperature Power Supply shall have a minimum operating temperature of-20°C or below when used in luminaires intended for outdoor applications. Maximum Measured Power Supply Case or Manufacturer Designated Temperature Measurement Point (TMPps)Temperature Not to exceed the power supply manufacturer maximum recommended case temperature orTMP when measured during in-situ operation. Note: This performance characteristic is separate and distinct from thermal requirements established by UL which governs safety rather than longevity of the power supply. All qualified luminaires are expected to meet this requirement, including linear, suspended, close-to-ceiling, IC, ICAT and Non-IC recessed canisters, etc. as well as those luminaires that may be exempt from UL1598. Output Operating Frequency > 120 Hz Note: This performance characteristic addresses problems with visible flicker due to low frequency operation and applies to steady-state as well as dimmed operation. Dimming operation shall meet the requirement at all light output levels. ENERGY STAR Program Requirements for SSL Luminaires - Version 1.3 ------- Electromagnetic and Radio Frequency Interference • Power supplies designated by the manufacturer for residential applications must meet FCC requirements for consumer use (FCC 47 CFR Part 15/18 Consumer Emission Limits). • Power supplies designated by the manufacturer for commercial applications must meet FCC requirements for non-consumer use (FCC 47 CFR Part 15/18 Non- consumer Emission Limits).

The line transient shall consist of seven strikes of a 100 kHz ring wave, 2.5 kV level, for both common mode and differential mode. Packaging Requirements Packaging Requirements Incompatibility with Controls and Application Exceptions Included documentation must clearly state any known incompatibility with photo-controls, dimmers or timing devices. ENERGY STAR Program Requirements for SSL Luminaires - Version 1.3 ------- Category A: Near-term Applications Comment on luminaire efficacy: The ENERGY STAR criteria for SSL Luminaires use Luminaire Efficacy to establish performance as defined below: Luminaire Light Output (includes fixture efficiency and thermal effects) Luminaire Efficacy = Luminaire Input Power The ENERGY STAR criteria for non-SSL residential light fixtures (commonly referred to as RLF) use system efficacy defined as the light output of the lamp-ballast system divided by the input power measured in a 25°C environment. Established test procedures for fluorescent sources support this approach. However, the program requirements in this document are based upon luminaire efficacy, instead of system efficacy for the following reasons: • Accurate measurement of the LED light source separate from the fixture is often not possible. LEDs typically are integrated into the fixture and not readily removable without altering the performance of the light source. • LED performance is significantly affected by elevated temperature. LED devices generate heat that is typically removed by an external heat sink, which may be designed into the luminaire itself. Separating the light source from its heat sink will significantly impact test results. There is no industry standard test procedure to measure system efficacy of LEDs. • Luminaire efficacy provides more realistic energy efficiency information because it accounts for power supply, thermal, and fixture losses, thus better meeting the needs of buyers who seek the most light output for the least energy input. ENERGY STAR Program Requirements for SSL Luminaires - Version 1.3 ------- Residential Applications Under-cabinet kitchen lighting Application Requirements Minimum Light Output Luminaire shall deliver a minimum of 125 lumens (initial) per lineal foot. The light output requirement is calculated by the following equation: Measured Fixture Length (inches) , , . , x x x „ — 2—1 -x125 = Minimum Required Light Output (lumens) Note: The equation applies to all luminaire configurations.

ENERGY STAR Program Requirements for SSL Luminaires - Version 1.3 ------- Standards and Documentation Comment on NVLAP accreditation: Several new standards and test procedures for solid state lighting were completed in 2008, including IESNA LM-79-08, IESNA LM-80-08, and ANSI C78.377-2008. Procedures to accredit laboratories for these test methods are currently under development by the National Institute for Standards and Testing (NIST), supported by DOE funding. Because accreditation was not yet available at the time DOE originally published the ENERGY STAR criteria for SSL, DOE suspended the NVLAP accreditation requirement for a period of one year from the effective date. The NVLAP accreditation procedure is expected to be published early in 2009. DOE will continue to monitor the accreditation process and will consider the timing and availability of accredited laboratories in any future modifications to this requirement. During the period of the NVLAP suspension, DOE will accept test results only from those laboratories on a pre-approved list compiled by DOE. The list of pre-approved laboratories, and the criteria used to select them, is posted on the ENERGY STAR website. The NVLAP accreditation requirement will be suspended for a period of one year from the effective date of the criteria. All applicants seeking product qualification on the basis of tests conducted by non-NVLAP laboratories during the suspension period may only submit test results from laboratories pre-approved by DOE. The list of pre-approved laboratories will be posted on the ENERGY STAR website.

ENERGY STAR Program Requirements for SSL Luminaires - Version 1.3 ------- Qualification Process Product Variations In recognition of the significant component substitution that occurs on a manufacturing production line, and in recognition of a range of product variations that may or may not have a material effect on product performance, these criteria allow for limited variation between products tested for qualification purposes, and products qualified as a result of those tests. Applicants may choose to qualify product groups as a single SKU (one SKU, some variations) or a SKU family (multiple SKUs, some variations). Applicants self define product groupings. Under either option, qualified products must be essentially identical to the tested product. Only limited variation is allowed. The table below summarizes allowable variations. Variations Within Product Groupings Housing/Chassis not allowed Heat Sink/Heat Management not allowed Finish allowed Reflector/Trim allowed Shade/Diffuser allowed Mounting allowed Light Source allowed, w/ conditions Power Supply allowed, w/ conditions As seen in the table, housing/chassis variations and heat sink/heat management component variations are not allowed, whether applying for a single SKU or SKU family, because they may materially impact LED performance. Finish, reflector/trim, and shade/diffuser variations are allowed. Light source and power supply variations are allowed, subject to conditions described below. Products qualified under a single application may include LED package(s)/module(s)/array(s) and power supplies from more than one manufacturer, but the LED package(s)/module(s)/array(s) and power supplies must be substitutable components used to manufacture essentially identical luminaires and must be intended to produce the same quantity and quality of light. LED package(s)/module(s)/array(s) and power supply substitutions intended to produce different CCT, CRI, total flux, and other quantitative and qualitative differences in light may not be included in a single product grouping. Further, all LED package(s)/module(s)/array(s) substitution components must separately comply with the Option 1 (Component Performance) requirements in the Lumen Maintenance section below. Lumen Maintenance Qualification The LM-80 test procedure prescribes lumen maintenance testing for the LED package(s)/module(s)/array(s) and/or the luminaire. The applicant may demonstrate compliance with either Option 1 (Component Performance) or Option 2 (Luminaire Performance). OPTION 1: Component Performance The Component Performance option allows the applicant to demonstrate compliance with the lumen maintenance requirement by demonstrating an LM-80 tested light source (package(s)/module(s)/array(s)) operates at or below specified temperatures when operated in situ. To be eligible for the component performance option, ALL three of the conditions below must be met. If ANY of the conditions are not met, the component performance option may not be used and the applicant must use the luminaire performance option for compliance. ENERGY STAR Program Requirements for SSL Luminaires - Version 1.3 ------- 1. The LED package(s)/module(s)/array(s) used in the fixture has/have been tested according to LM-80, and the package(s)/module(s)/array(s) demonstrated at least 91.8% lumen maintenance at 6,000 hours (residential indoor) or 94.1% lumen maintenance at 6,000 (residential outdoor and all non- residential). 2. The package(s)/module(s)/array(s) manufacturer prescribes/indicates a temperature measurement point (TMPled) on the package(s)/module(s)/array(s). 3. The package(s)/module(s)/array(s) TMPLed is accessible to allow temporary attachment of a thermocouple for measurement of in situ temperature. Access via a temporary hole in the housing, tightly resealed during testing with putty or other flexible sealant is allowable. The luminaire PASSES the Lumen Maintenance requirements if: 1. The package(s)/module(s)/array(s) temperature measured in situ, at the TMPLed is less than or equal to the temperature(s) specified in the LM-80 test report for the corresponding drive current or higher, within the manufacturer's specified operating current range. 2. The drive current measured in the fixture is less than or equal to the drive current specified in the LM- 80 test report at the corresponding temperature or higher. OPTION 2: Luminaire Performance The applicant demonstrates compliance with the lumen maintenance requirement by submitting an LM-80 test report for the entire luminaire.

ENERGY STAR Program Requirements for SSL Luminaires - Version 1.3 ------- Qualification Procedures Qualification procedures are described in detail in the following documents: 1. ENERGY STAR® Manufacturer's Guide for Qualifying Solid-State Lighting Luminaires, September 2008, http://www.enerqvstar.gov/ia/partners/manuf res/downloads/ENERGYSTAR Manufacturers Guide 30Sept0 8.pdf 2. Instructions For Partnering With ENERGY STAR® As A Manufacturer Of ENERGY STAR Qualified Products http://www.enerqvstar.qov/ia/partners/manuf res/downloads/ENERGYSTAR Manufacturer Partnership Aqr eement.pdf Quality Assurance (QA) Testing Manufacturer partners selling approved ENERGY STAR SSL luminaires will be required to participate in a quality assurance testing program, which will use independent, third-party, qualified testing facilities. This third-party testing program is necessary to provide an active system to verify quality of ENERGY STAR qualified SSL Luminaire products in the marketplace. The information provided below is a general description and summary of the QA testing program. Detailed policies and procedures will be available in the ENERGY STAR SSL Quality Assurance Testing Program Manual. A. Overview: Qualified luminaires will be selected for QA testing both on a random basis and through a product nomination process. The manufacturer of each selected luminaire will be required to commission third-party testing of the specified luminaire by a manufacturer-independent qualified testing lab. The testing lab will procure three (3) samples of each luminaire through normal market channels. Each luminaire will be tested for: ¦ Total Luminous Flux ¦ Luminaire Efficacy ¦ Correlated Color Temperature ¦ Color Rendering Index ¦ Steady State Package/Module/Array Temperature ¦ Maximum Power Supply Case/TMPPS Temperature Results of Non-Compliance. Partners shall refer to EPA's stakeholder letter dated July 20, 2010 (available at www.enenqvstar.gov) for the product disqualification procedures and corrective action requirements. A separate document will be developed by EPA to define the specifics of the quality assurance testing (QA) intended to accompany these criteria. ENERGY STAR Program Requirements for SSL Luminaires - Version 1.3 ------- Effective Date The effective date for the ENERGY STAR Program Requirements and Criteria for SSL - Version 1.3 is February 1, 2009. Future Specification Revisions Due to the rapid pace of LED technology development, EPA anticipates regular revisions to these criteria. EPA anticipates that new applications will be added to the criteria as LED performance and efficacy improve. Revisions will be announced to all partners with time for input and review.

Each of the eight quadrangles as defined below overlap the six current the ANSI 7-step MacAdarn ellipses (consistent with the current ENERGY STAR lighting criteria), and thus have the same nominal CCT as ENERGY STAR fluorescent lamps. Two additional CCTs (4500 and 5700K) are included to encompass the additional CCTs available in SSL. Each quadrangle is defined by the range of CCT and the distance from the Planckian locus on the chromaticity diagram. Refer to ANSI C78.377-2008 for the details of these definitions. Figure 1 shows the plot of these chromaticity quadrangles and the table below shows (x,y) coordinates of the center points and the corners of each quadrangle. 2700 K 3000 K 3500 K 4000 K 4500 K 5000 K 5700 K 6500 K X y X y X y X y X y X y X y X y Center point 0.4578 0.4101 0.4338 0.4030 0.4073 0.3917 0.3818 0.3797 0.3611 0.3658 0.3447 0.3553 0.3287 0.3417 0.3123 0.3282 Tolerance quadrangle 0.4813 0.4319 0.4562 0.4260 0.4299 0.4165 0.4006 0.4044 0.3736 0.3874 0.3551 0.3760 0.3376 0.3616 0.3205 0.3481 0.4562 0.4260 0.4299 0.4165 0.3996 0.4015 0.3736 0.3874 0.3548 0.3736 0.3376 0.3616 0.3207 0.3462 0.3028 0.3304 0.4373 0.3893 0.4147 0.3814 0.3889 0.3690 0.3670 0.3578 0.3512 0.3465 0.3366 0.3369 0.3222 0.3243 0.3068 0.3113 0.4593 0.3944 0.4373 0.3893 0.4147 0.3814 0.3898 0.3716 0.3670 0.3578 0.3515 0.3487 0.3366 0.3369 0.3221 0.3261 CIE1931 x,y Chromaticity Diagram 0.46 2700 K 3000 0.44 3500 K 0.42 4000 K 0.40 4500 K 5000 K 0.38 5700 y 0.36 6500 K 0.34 ° llluminant A A.
