LED Luminaires

LED Roadway Luminaires are classified by their High Pressure Sodium (HPS) wattage equivalent, as described in Standard Specification 9-29.10(1)B (see Division 9 of the Standard Specifications). The lists provided here are separated by luminaire form type, such as cobra-head or wall mount. It is important that you refresh this page every time you visit to ensure that you are getting the most up to date versions of any posted lists.

Each list includes effective approval dates for each luminaire. Previously approved luminaires are included in the superseded list, with an expiration date once they have been superseded. Contracts that have already been awarded may use any luminaire that has been approved at the time of award, including any from the current approved list and any from the superseded list that have an expiration date after the date of contract award. Contractors should include a copy of the list that they are using as part of any material submittals, with the applicable part number(s) highlighted.

LED Luminaire Photometric Evaluation Criteria

To ensure that LED luminaires are interchangeable with both existing HPS inventory and future iterations of LED luminaires, LED Roadway Luminaires are categorized by Wattage Class. The criteria for evaluating and classifying LED luminaires, as well as copies of the AGi32 test grid files, are available here.

WSDOT Evaluation Criteria for LED Luminaires (PDF 111KB) Updated January 2021
WSDOT AGi32 Test Grids for Cobra-Head Type Luminaires (ZIP 2.32MB)

The AGi32 files provided here are for version 19 and later. Due to changes made by the software manufacturer starting with version 19, these files are not compatible with versions of AGi32 earlier than version 19.

Submitting a new LED luminaire for approval

To submit a new LED luminaire for approval, you must first make a request through the QPL System. Due to the amount of time needed for photometric and physical review and approval, new LED luminaires cannot be submitted as part of a construction contract - only pre-approved LED luminaires may be submitted.

Once the QPL process is started and an ID is provided, the photometric evaluation will be completed before any payments are requested. Do not send any payments until directed by the QPL Engineer.

Manufacturers and/or vendors submitting new LED luminaires through the QPL process for approval need to provide both of the following to complete the photometric evaluation:

  • The test grid files with the luminaire(s) to be evaluated loaded and all calculations run.
  • A results report as described in the evaluation criteria document.

WSDOT will re-run the AGi32 calculation files for verification. Once the photometrics have been verified to be run correctly and meet the required criteria, the submitter and the QPL Engineer will be notified and the QPL process will proceed to physical evaluation.

LED Luminaire wattage labels

Consistent with the LED wattage classification system, WSDOT uses a modified version of the standard ANSI/NEMA C136.15 label on LED luminaires. Details of this modified label are available here.

Electrical and Communications Boxes and Vaults

Electrical and communications systems junction boxes (sometimes referred to as in ground "hand-holes") and utility vaults require an approved shop drawing for use in WSDOT systems. The following boxes and vaults have approved drawings on file for fabrication inspection and approval.

Boxes and vaults are broken down into three basic groups - use the links below to jump to that group:

Standard Duty Junction Boxes (Type 1, Type 2, and Type 8)

Heavy Duty Junction Boxes (Type 4, Type 5, and Type 6)

Utility Vaults (Pull Boxes, Small Cable Vaults, and Cable Vaults)

Utility Vaults

Standard duty and heavy duty pull boxes and cable vaults are listed together because they use the same lower box with either a standard duty or a heavy duty lids. There are no heavy-duty small cable vaults due to the design of the vault lid (not a separate reinforced assembly).

ITS Proprietary (Sole-Source) Equipment

Some equipment cannot be supplied through an open performance specification due to compatibility with existing software and equipment or similar issues. Where this is the case, proprietary approval for equipment in a specific application has been provided. This equipment is evaluated every two years at a minimum, with items that can be covered under an open performance specification moved from proprietary approval to QPL approval under the applicable standard(s).
