Sample Procurement Language (Download Residential Lighting Procurement Language Word document)

The following is an example of language you may wish to require in your upcoming contract:

Residential Light Fixtures (Indoor)

The Vendor Must:
Provide indoor residential light fixtures that earn the ENERGY STAR and meet the ENERGY STAR specifications for energy efficiency as outlined below. The vendor is encouraged to visit energystar.gov for complete product specifications and an updated list of qualifying products.

Performance Characteristic Current Criteria
Note: Only electronic ballasts may be used to meet the requirements of this table. In addition, fixtures that utilize compact fluorescent lamps that do not have a plug-in base (i.e use a mogul, medium, or other screw base) are not eligible to earn the ENERGY STAR.
Efficiency System Efficacy, per lamp ballast combination >= 50 LPW for all lamp types below 30 total listed lamp watts.
>= 60 LPW for all lamp types that are <= 24 inches and >= 30 listed lamp watts.
>= 70 LPW for all lamp types that are > 24 inches and >= 30 listed lamp watts.

Performance Characteristics for Lamps:

Lamp Life

For lamps shipped with the fixtures, the average rated life of the lamp must be >= 10,000 hours.

If the lamp is not shipped with the fixture, product packaging must meet the requirements set forth in the “Product Packaging for Consumer Awareness” section of this Table.

Lumen Maintenance For lamps indicated on the fixture packaging or shipped with the fixtures, the lamp shall have an average rated lumen maintenance of at least 80% of initial lamp lumens at 40% (4,000 hours minimum) rated lamp life.
Color Rendering Index

For lamps shipped with the fixtures, the color rendering index must meet the following requirements:

  • >= 80 for compact fluorescent lamps.
  • >= 75 for linear fluorescent lamps.

If the lamp is not shipped with the fixture, product packaging must meet the requirements set forth in the “Product Packaging for Consumer Awareness” section of this Table.

Correlated Color Temperature

For lamps shipped with the fixtures, the lamps must have one of the following designated correlated color temperatures (CCT): 2700K, 3000K, 3500K, 4100K, 5000K, or 6500K.

If the lamp is not shipped with the fixture, product packaging must meet the requirements set forth in the “Product Packaging for Consumer Awareness” section of this Table.

Lamp/Lampholder Compatibility

For lamps indicated on the fixture packaging or shipped with the fixtures, lamps must utilize an ANSI/IEC standardized lamp base configuration, as defined by ANSI C81.61 and IEC 60061-1.

The lampholder must be designed to accept lamps with ANSI/IEC standardized lamp base configurations for all applicable wattages. For example, if the ballast can operate lamps with multiple wattages (e.g., an 18W, 26W, or 32W lamp) then the lampholder must be designed to accept lamps with ANSI/IEC standardized lamp base configurations for all three applicable wattages.

In addition, lamps shall either:

  • Meet the requirements of an ANSI/IEC standardized lamp specification sheet, as defined by ANSI C78.901-2001 and IEC 60901 (for compact fluorescent lamps) or ANSI C78.81-2001 and IEC 60081 (for linear lamps) if an applicable standard exists, or,
  • If no ANSI/IEC lamp standard exists (e.g., a spiral compact fluorescent lamp), a custom lamp specification sheet must be provided at the time of submittal. Specific lamp characteristics that should be included in the lamp specification sheet are detailed in Table 3.
Lamp Labeling Requirement For lamps shipped with fixtures, a manufacturer designation that encompasses the lamp manufacturer name, wattage, correlated color temperature, and color rendering index must be labeled on the lamp or lamp base.

Performance Characteristics and Durability for Electronic Ballasts

(Note: Magnetic Ballasts May Not Be Used in Indoor Fixtures):

General Per ANSI C82.11 Section 5 except paragraph 5.3.1.
Lamp Start Time The time needed after switching on the lamp to start continuously and remain illuminated must be an average of one second or less.
Power Factor >= 0.5
Lamp Current Crest Factor <= 1.7
Maximum Measured Ballast Case Temperature During Normal Operation Inside Fixture(s)

Not to exceed the ballast manufacturer maximum recommended ballast case temperature during normal operation inside a fixture.

Note: This performance characteristic is separate and distinct from thermal requirements established by UL, which governs safety rather than longevity of the ballast. All qualified fixtures are expected to meet this requirement, including linear, suspended, close-to-ceiling, IC, ICAT and Non-IC recessed canisters, etc. as well as those fixtures that may be exempt from UL1598.

Electromagnetic and Radio Frequency Interference Ballast must meet FCC requirements for consumer use (FCC 47 CFR Part 18 Consumer Emission Limits)
Ballast Frequency 20 to 33 kHz or >= 40 kHz
Transient Protection Per ANSI C82.11b, paragraph 5.10.1 (100kHz Ring Wave, 2.5kV, both common mode and differential mode, 7 strikes)
End of Life Protection All ballasts that operate lamps sized T5 and smaller must contain an end of life protection circuit. For ballasts that operate multiple lamps and are required to have end of life protection, the ballast must shut down no more than two lamps when one of the lamps has reached end of life. For example, a fixture with one ballast and five lamps must not shut down more than the lamp that has reached end of life plus one additional lamp.
Dimming

Torchiere style portable fixtures shall be dimmable from 100% to 30%, or less, of maximum light output, or be switchable to three levels of brightness, not including the off position.

Other fixture types that utilize dimmable ballasts shall be dimmable from 100% to 30%, or less, of maximum light output, or be switchable to three levels of brightness, not including the off position.

Safety — Ballasts and “Non Edison base Fluorescent Adapters” The cover page of a safety test report or a general coverage statement must be provided to demonstrate compliance with ANSI/UL 935 or UL 1993, as appropriate.

Fixture Performance Characteristics:

Fixture Warranty A written warranty must be included with fixture packaging at the time of shipment, which covers repair or replacement of defective parts of the fixture housing, optics, trim and electronics (excluding the lamp) for a minimum of two years from the date of purchase.
Noise Class A sound rating for electronic ballasts within the fixture, not to exceed a measured level of 24 dBA (audible) when the ballast is installed in the fixture.
Lamp Shipment Requirement

All indoor fixtures must be shipped with a lamp, except for the following fixture types:

  1. Recessed downlight fixtures and recessed downlight retrofit kits
  2. Fixtures using linear fluorescent lamps
Replaceable ballast Ballasts in all fixtures (including portables) must be accessible and removable by an electrician without the cutting of wires and without damage to the fixture housing, trim, decorative elements or the carpentry (e.g., ceiling drywall) to which the fixture is attached.
Safety — Portable Fixtures The cover page of a safety test report or a general coverage statement must be provided to demonstrate compliance with ANSI/UL 153.
Safety — Hardwired Fixtures The cover page of a safety test report or a general coverage statement must be provided to demonstrate compliance with UL 1598.
Recessed Downlight Fixtures — Insulation Contact (IC)-Rated Recessed downlight fixtures that are either IC-Rated for direct contact with insulation or non IC-Rated may qualify as ENERGY STAR. For fixtures to be considered IC-Rated they must be approved for zero clearance insulation cover (IC) by an OSHA NRTL laboratory. Recessed downlight fixtures that are IC-Rated must also meet the requirements for air tight fixtures, listed below.
Recessed Downlight Fixtures — Air Tight For Restricted Air Movement

Recessed downlight fixtures that are either air tight or not air tight may qualify as ENERGY STAR. For fixtures to be considered air tight, the housing or certified/listed accessory must have leakage less than 2.0 cubic feet per minute (CFM) at 75 Pascals (or 1.57 lbs/ft2) when tested in accordance with ASTM E283 and shall be sealed with a gasket or caulk.

For recessed downlight fixtures that are air tight, the following measures must be taken to ensure that fixtures can be properly installed and inspected:

  1. Product packaging must meet the requirements set forth in the “Product Packaging for Consumer Awareness Requirements” section below.
  2. The fixture itself must include a label certifying “air tight”, or similar designation, to show air leakage less than 2.0 CFM at 75 Pascals when tested in accordance with ASTM E283. The label must be clearly visible to a building inspector.
  3. Installation instructions must be included listing all components of the assembly that will be necessary to ensure an airtight installation and how the components should be properly installed. For example, depending on the method used to achieve air-tight operation, the instructions should alternatively show how a gasket is to be attached, what type of caulk to use and how it should be applied, or which certified airtight trim kits are designed to be installed with the luminaire housing.
Product Packaging for Consumer Awareness Requirements

For fixtures that are not shipped with lamps, product packaging must include a list of lamps types that would ensure ENERGY STAR quality and performance when paired with the qualifying fixture. This list must be clearly visible to the consumer on the fixture packaging.

Manufacturers are not required to provide specific lamp manufacturer names and model numbers on the packaging. Rather, generic lamp listings, such as the NEMA or ANSI generic descriptions including a color designation (e.g., F32T8/830 or CFQ26W/G24q/827), will suffice. In addition, packaging should suggest that consumers select a lamp with a rated life of 10,000 hours or more. Note: only recessed downlight fixtures, recessed downlight retrofit kits, and fixtures using linear lamps may ship without a lamp.

For fixtures that are shipped with lamps, product packaging language is required that clearly describes the nominal color designation of the lamp in units of Kelvin (i.e., 2700K, 3000K, 3500K, 4100K, 5000K, or 6500K). For recessed downlight fixtures that are IC-Rated, product packaging must clearly state this rating. The language must be clearly visible on the product packaging. The IC-Rated designation will also be included in the fixture description included in the Qualified Product list posted on the ENERGY STAR Web site. Sample language: “IC-Rated for direct contact with insulation”.

For recessed downlight fixtures that are Air-Tight (AT) rated, product packaging must clearly show that the fixture produces less air leakage than 2.0 CFM at 75 Pascals when tested in accordance with ASTM E283. The language must be clearly visible on the product packaging. The “air tight”, or similar, designation will also be included in the fixture description included in the Qualified Product list posted on the ENERGY STAR Web site. Sample language: “Certified Air Tight per ASTM E283.”

Additional Requirements for Indoor Recessed Downlight Retrofit Kits:

Reflectors Reflectors must be included to maximize fixture efficiency.
Aperture Maximum 7.0"
Air Tight For Restricted Air Movement

Only recessed downlight retrofit kits that are air tight may qualify as ENERGY STAR. For fixtures to be considered air tight, the housing or certified/listed accessory must have leakage less than 2.0 cubic feet per minute (CFM) at 75 Pascals (or 1.57 lbs/ft2) when tested in accordance with ASTM E283 and shall be sealed with a gasket or caulk.

For recessed downlight retrofit fixtures, the following measures must be taken to ensure that fixtures can be properly installed and inspected:

  1. Product packaging must meet the requirements set forth in the “Product Packaging for Consumer Awareness” section within this table, below.
  2. The fixture itself must include a label certifying airtight or similar designation to show air leakage less than 2.0 CFM at 75 Pascals when tested in accordance with ASTM E283. The label must be clearly visible to a building inspector.
  3. Installation instructions must be included listing all components of the assembly that will be necessary to ensure an airtight installation and how the components should be properly installed. For example, depending on the method used to achieve air-tight operation, the instructions should alternatively show how a gasket is to be attached, what type of caulk to use and how it should be applied, or which certified airtight trim kits are designed to be installed with the luminaire housing.
Electrical Connections Edison lamp socket with wire “pigtail” to the ballast.
Safety — Fixture Conversions, Retrofits

Fixtures must be tested and listed by an OSHA NRTL laboratory as acceptable for compliance with NFPA 70, National Electrical Code (NEC).

The cover page of a safety test report or a general coverage statement must be provided to demonstrate compliance with UL 1598 and UL 1598B.

Product Packaging for Consumer Awareness Requirements

Recessed downlight retrofit kit packaging and instructions must clearly indicate:

  1. What fixture model numbers the recessed downlight retrofit kits are compatible with.
  2. Whether or not the product is dimmable. If dimmable, user instructions must clearly indicate what type of dimming circuit it can be used on.
  3. Any known incompatibility with photo controls, dimmers or timing devices.
  4. Airtight or similar designation to show air leakage less than 2.0 CFM at 75 Pascals when tested in accordance with ASTM E283. The language must be clearly visible on the product packaging. The “air tight”, or similar, designation will also be included in the fixture description included in the Qualified Product list posted on the ENERGY STAR Web site. Sample language: “Certified Air Tight per ASTM E283.”
