6. Background. This ETL is required because (1) the recently published UFC 3-530-01,
Change 1, does not provide guidance for Service-specific applications; and (2) there are
no Unified Facility Guide Specifications (UFGS) for LED luminaires.
7. Interior LED Luminaires. LED luminaires are permitted only for those interior
applications identified in UFC 3-530-01, Change 1.
8. Exterior LED Luminaires.
8.1. Prohibited Applications.
4
8.1.1. Solar-powered or combination solar- and utility-powered LED luminaires
are prohibited unless all the following conditions are satisfied:
• the project is econonmically viable with Energy Savings Performance
Contracts or third-party financing;
• the luminaires are for exterior use only;
• the project reduces maintenance requirements;
• the project meets the ten-year pay back requirement (paragraph 9.1);
• the project is approved by AFCEC/CN and AFCEC/CO.
Note 1: For use of solar LED in contingency environments, consult ETL 12-12,
Solar-Powered Light-Emitting Diode (LED) Fixture Design and Installation
Criteria for Exterior Lighting Applications in Contingency Environments.
8.1.2. LED luminaires that require remote mounting of any component needed
for operation — such as ballasts, drivers, light engine electronics, or other
controls — are not allowed. Components needed to make the fixture operational
shall be integral to the fixture housing.
8.1.3. Retrofit conversion of LED lamps or LED lighting module inserts designed
and constructed for use in existing high-intensity discharge (HID) luminaires —
including metal halide, mercury vapor, or fluorescent fixture enclosures — are
prohibited. Only new, complete-assembly LED luminaires shall be used.
Note 1: Retrofit project installations are defined as inserting LED technology into
existing fixture housings.
Note 2: Replacement project installations are defined as replacing existing
luminaires with new LED luminaires.
8.2. Applications Requiring Pre-Approval.
8.2.1. Use of LED luminaires for airfield ramp, alert, security, or munitions area
lighting requires AFCEC/CO prior approval due to potential interference with night
vision goggles.
8.2.2. Local area network (LAN), wireless, radio, modem, power line carrier, or other
communication methods used for LED light fixture control must be be approved in
accordance with ETL 11-1, Civil Engineer Industrial Control System Information
Assurance Compliance.
9. LED Project Considerations. Prior to authorizing any LED lighting project, the
base energy manager and MAJCOM electrical engineer or MAJCOM energy manager
shall review and approve the calculation methods, assumptions, and resulting
justification for the proposed LED lighting project, and review the project for compliance
with paragraphs 9.1 through 9.3.
5
9.1. Approval for an LED lighting project shall be based on a ten-year payback
(return on investment [ROI]). Before awarding a contract to acquire LED lighting,
ROI shall be computed and approved by the MAJCOM electrical engineer or energy
manager. If the investment does not have a positive ROI, or if there are other
opportunities with a higher ROI, the investment should not be undertaken. To
calculate the ROI, the benefit (return) of an investment is divided by the cost of the
investment; the result is expressed as a percentage or ratio:
ROI =
Gain from Investment − Cost of Investment
Cost of Investment
9.2. Use of life-cycle cost software, such as the Building Life-Cycle Cost program
(BLCC) or Economic Analysis Package (ECONPACK), is required.
These
applications are available at http://www.wbdg.org/tools/tools_cat.php?c=3. Life-cycle
cost analysis shall include, but is not limited to, sustainment, restoration, recapitalization, operation (to include energy), and initial capital investment. Net present
value (NPV), savings-to-investment ratio (SIR), or internal rate of return (IRR)
calculations shall indicate the project is a favorable investment as dictated by Office of
Management and Budget (OMB) Circular A94, "Guidelines and Discount Rates for
Benefit-Cost Analysis of Federal Programs," and further supplemented by National
Institute of Standards and Technology (NIST) Handbook 135, Life-Cycle Costing
Manual for the Federal Energy Management Program. Further programming criteria
are available at the Air Force Facility Energy Program Community of Practice (CoP),
https://askn.wpafb.af.mil/community/views/home.aspx?filter=OO-EN-CE-A4.
9.3. Additional calculations may be required depending upon programming funding
avenues; e.g., Energy Conservation Investment Program (ECIP); energy focus funds
(NRG); Sustainment/ Restoration, & Modernization (SRM).
10. Design and Siting Requirements.
10.1. Design Criteria. LED lighting installations shall incorporate a lighting design
certified to meet criteria in applicable AFIs, UFCs, ETLs, and Illuminating
Engineering Society of North America (IESNA) standards. Exceptions include:
• Exit signs
• General signage
• Traffic signals
• Step lighting
• Directional accent lights and other low-level lighting applications
Note 1: Design is any calculation, analysis, field testing, or other engineering
methodology that ensures products and installation (LED lighting system) meet
applicable statutes, standards, and criteria, including field measurement and
verification requirements within this ETL.
6
Note 2: Projects must be certified by an individual qualified in lighting design. This
may include the design agent, installation contractor or vendor.
Note 3: A qualified individual is one who has the skills and knowledge related to the
calculation, design, construction, installation, and operation of lighting systems; and
has received training concerning types and application of light sources, field
measurement equipment, luminaires, and their placement, to comply with applicable
standards and criteria including those outlined in this ETL.
10.2. Environmental Considerations.
The Asset Management Environmental
Element shall be consulted before installation of an LED luminaire.
10.2.1. LED luminaire installations shall meet all federal, state, and local
governing authority environmental requirements, as well as applicable base
natural infrastructure asset management plan requirements; e.g., wildlife habitat,
observatories, wildlife nesting, and dark sky requirements.
The lighting
manufacturer is responsible for obtaining any applicable certifications for their
products. Approval certifications shall become part of the project record.
10.2.2. When approved by the Asset Management Environmental Element, LED
luminaires may be used where low-pressure sodium lighting is specified for sea
turtle nesting areas as described in UFC 3-530-01, and shall meet requirements
in paragraph 10.2.1.
10.3. Field Measurements.
10.3.1. Initial Measurements. Initial field measurements shall be taken following
installation to certify design standards addressed in paragraphs 10.1 and 10.2
have been satisfied.
10.3.2. Measurements Prior to Warranty Expiration. Warranty field measurements
shall be taken to verify minimum luminaire output before the luminaire warranty
expires.
Note: LEDs typically do not fail catastrophically, but instead dim over time. To
ensure performance, a second set of measurements shall be taken before the
warranty expires. See Attachment 1, paragraph 1-8, “Warranty.”
10.3.3. Records. Copies of the field measurement reports shall be incorporated
into project records.
10.4. Technical Specifications. LED fixture design, component specifications,
submittals, and installation criteria shall comply with UFC 3-530-01, IESNA
standards, and the requirements in Attachment 1.
7
Note: For replacement projects, ensure supporting infrastructure (e.g., light poles,
exterior structural walls) is capable of supporting replacement luminaires. Facility
modifications or unnecessary penetrations shall be minimized.
10.5. Surge Protection. Surge protection internal to the luminaire shall comply with
Attachment 1.
Note: To protect the initial LED luminaire cost investment, it is highly recommended
that additional surge protection external to the luminaire be considered in any LED
project. This can be accomplished by installing surge protection devices at
distribution panelboads, equipment disconnects, or by installing light pole-type
lightning arrestors at the light pole where LED luminaires are mounted. Compliance
with UL 1449, Surge Protective Devices, 3rd edition, is required.
11. Contracting Requirements.
11.1. Requirements and specifications in this ETL shall be incorporated into
applicable contracting documents.
11.2. LED fixture manufacturers shall submit written certification that their
luminaires comply with Attachment 1. The certification shall be included in the first
submittal from the contractor.
Incomplete and/or incorrect information is
unacceptable and will result in the light fixture failing to meet Air Force requirements.
11.3. Materials and equipment shall be sourced from manufacturers who are
regularly engaged in production of LED lighting products. The manufacturers’
products shall have been in satisfactory commercial or industrial use for two (2)
years prior to bid opening. The two-year period shall include applications of
equipment and materials under similar circumstances and of similar size.
Technology used may be less than two years old. The manufacturers’ products
shall have been on sale on the commercial market through advertisements,
manufacturers' catalogs, or brochures, during the two-year period. Where two or
more items of the same class of equipment are required, these items shall be
acquired from a single manufacturer. Component parts of the item need not be
products from the same manufacturer unless specifically required by this ETL.
12. Warranties. LED fixture construction and installation warranties shall be provided
in accordance with Attachment 1 and paragraphs 12.1 and 12.2.
12.1. The contractor shall install luminaires in accordance with the design
engineer’s and manufacturer’s requirements.
12.2. LED luminaire warranties shall begin on the date of final acceptance of the
installation by the contracting officer or designated representative, as executed by
DD Form 1354, Transfer and Acceptance of DOD Real Property.

WARRANTY
LED luminaires and replacement lamps available today claim long life (e.g., 50,000
hours or more), which exceeds the life ratings of nearly all other light sources (except
for some electrodeless sources). These claims are based on the estimated lumen
depreciation of the LED used in the product and often do not account for other
components or failure modes. Projected life of LED luminaires is a key component to
payback scenarios in project evaluations; therefore, it is critical that products perform as
promised and anticipated. Since life claims provided by suppliers are typically 50,000
hours or more and the initial cost of exterior LED luminaires may be significant,
warranties shall include product performance as claimed in terms of useful life.
Life claims by LED luminaire manufacturers shall take into account the whole system,
not just the LEDs. A key lesson learned from early market introduction of compact
fluorescent lamps was that long-life claims need to be credible and backed up with
adequate manufacturer warranties.
Equipment items shall be supported by service organizations that are reasonably
convenient to the equipment installation in order to render satisfactory service to the
equipment on a regular and emergency basis during the warranty period of the contract.
Note: On-site replacement includes transportation, removal, and installation of new
products.
Atch 1
(5 of 10)
a. The LED manufacturer shall provide a written five-year on-site replacement
“finish” warranty for luminaires. Finish warranty shall include warranty against
failure or substantial deterioration such as blistering, cracking, peeling,
chalking, or fading.
b. The LED manufacturer shall provide a written five-year on-site replacement
warranty for defective or non-starting power supply units and LED source
assemblies, which include, but are not limited to, LED packages, LED arrays,
LED modules, LED dies, encapsulates, and phosphors.
c. The LED manufacturer shall provide a written five-year on-site replacement
warranty for any LED source assembly, package, array, or module, which does
not include the power supply, against 10% or more of the individual LEDs in
that assembly, package, array, or module failing to illuminate.
d. The LED manufacturer warranty period shall begin on the date of final
acceptance, as executed by a DD Form 1354. The contractor will provide the
contracting officer with the signed warranty certificates prior to final payment.
PART 2 PRODUCTS

adjustment of ±5°, in accordance with ANSI C136.3.
t. Luminaires must pass 3G vibration testing in accordance with ANSI C136.31.
u. Luminaires shall have surge protection to meet “C Low” waveforms as defined
in ANSI/IEEE C62.41.2, Scenario 1 Location Category C.
v. Luminaires shall incorporate provisions to attach a twist-lock style photocell.
2-1.2 WIRING
Twist-style wire nuts and tap-style stripless connectors are not acceptable for factory
electrical connections.
2-1.3 POWER SUPPLY UNITS
Note 1: Remove bracketed options that are not applicable to your project.
Note 2: Normal ambient temperature of 40 °C (104 °F) will be adequate for typical nighttime operating environments. Selection of 50 °C (122 °F) will increase the system cost and
should be used when required for a specific project location. Coordinate with [40] [50]
bracketed options in other parts of specification as well. Use a dimmable driver for all
applications that may utilize controls (e.g., curfew, motion sensing) as part of the project.
a. Minimum efficiency of 85%.
b. The maximum drive current to each individual LED shall not exceed 600 mA.
c. Rated to operate between -30 °C to [+40 °C] [+50 °C].
d. Designed to operate on voltage system [120V to 277V] [480V] nominal.
Fluctuations in line voltage up to 15% shall have no visible effect on the
luminous output.
e. Operating frequency: 50/60 Hz.

f. Power factor (PF): ≥ 0.90.
g. Total current harmonic distortion (THD) for current: ≤ 20%.
h. Comply with FCC 47 CFR Section 15, Class B, non-consumer RFI/EMI
standards.
i.
Reduction of hazardous substances- (RoHS-) compliant.
j.
Luminaires under a covered structure shall be UL-listed Class P with a sound
rating of “A.”
k. Driver shall be dimmable and compatible with standard dimming control circuits.
l.
Driver shall be protected against damage due to either an open-circuit or shortcircuit fault condition on the driver output. The driver shall resume normal
operation when the fault is removed.
m. Over-temperature protection shall be provided to cut off output power if
temperature limit is exceeded. The driver shall resume normal operation when
within normal operating temperature.
2-1.4 LED LIGHT SOURCE
Note 1: Select CCT values and CRI bracketed options based on application. If a
design strategy is to blend with traditional lighting systems in the local area, pick a CCT
in the 4,000-5,000 K range. This temperature is a warmer light source than 6500 K and
provides a balance between color temperature, color rendering, and efficacy of the light
source. LED chips are manufactured to achieve maximum efficacy related to a specific
color temperature and this varies with chip manufacturer and binning.
Note 2: High pressure sodium is 2700 K, warm metal halide is 3200 K, clear metal
halide is 4000 K, and moonlight is 4100 K.
Note 3: 6500 K is a cooler temperature and should only be used when color rendering
or environmental concerns such as sky glow are not a factor. Objects appear bluish
and items in the red color spectrum may appear distorted.
a. Correlated color temperature (CCT) shall be in accordance with ANSI C78.377.
