​Eligibility for Enhanced Lighting Program

  1. The lighting power density (LPD) of the building after project completion must be at least a 10 percent improvement from that required by the Washington State Energy Code (section 1530) effective at the time of project completion. 
  2. All interior and exterior lighting on the qualifying PSE account must be included. Exterior lighting must be included if it is the responsibility of the business being retrofitted. This includes wall packs, walk-way lighting, façade lighting, decorative lighting, and parking lot lighting.
  3. All T12 lighting fixtures must be replaced or retrofitted with new fixtures utilizing T8, T5 or T5HO lamps and must save at least 25 percent. Another technology that results in an energy savings of at least 25 percent may be substituted. 
  4. Newly installed T8 ballasts must be “instant start” ballasts. Programmed “rapid start” ballasts may be used only if occupancy or dimming controls are included which meet the current Washington State Energy Code requirements. All new ballasts must be NEMA Premium labeled or listed on CEE’s list of qualifying 120- and 277-volt ballasts.
  5. Low wattage T8s listed on CEE’s list of qualifying “Reduced-Wattage T8 Lamps” shall be used on all new or retrofit T8 fixtures. Additionally, all existing 32-watt T8 lamps must be replaced with low-wattage T8 lamps from CEE’s list of qualifying “Reduced-Wattage T8 Lamps”. If the normal temperature in a space is below 60F, or a situation exists for which no available qualifying low-wattage T8 lamp is appropriate, 32-watt lamps may remain in place with PSE approval.
  6. Metal halide and other High Intensity Discharge (HID) lighting must be replaced or retrofit using T8/T5/T5HO fluorescent, CFL, LED,  pulse start metal halide or other similarly efficient technology if a 20 percent lighting power reduction is achievable. 
  7. Incandescent and fluorescent exit signs must be replaced with LED exit signs that have a five-year manufacturer’s warranty and use 5 watts or less. Models equipped with “bug eyes” or other emergency options will be required to use 5 watts or less when the emergency options are not energized.
  8. All incandescent lamps must be replaced with qualifying LED, CFL or T8 lighting.
  9. Lighting controls must be installed where they would be required by the current Washington State Energy Code, if the building were being built new at the time of the project, with the exception of section 1513.3 - Daylight Zone Control requirements. If not otherwise required by current code, automatic lighting controls must be installed in the following places:
    • Individual offices
    • Restrooms
    • Open plan office spaces
    • Parking garages and lots
    • High bay spaces (warehouses, barns, gyms, etc.)
    • Exterior area lighting
    • Stairwells
  10. Care should be given to selecting proper ballasts designed for use with frequently energized and de-energized lighting (i.e. programed “rapid start” ballasts) when appropriate.
  11. 11. LED products may be installed if they are on one of the three following lists. All lists can be found on the Lighting Design Lab website:
    • ENERGY STAR® qualifying commercial LED lighting products
    • Design Lights Consortium list of qualifying products 
    • Lighting Design Lab list of qualifying products or meet the qualifications to be on the Lighting Design Lab list
  12. CFL products may be used if they are currently listed by ENERGY STAR on their list of qualified CFL lamps.
  13. Cold cathode lamps do not have to be ENERGY STAR qualified, but must have at least a two-year warranty and produce at least 35 lumens per watt. 
  14. Other lighting technologies may be permitted, with pre-approval from PSE, if demonstrated to be more efficient and cost effective than other options if all other criteria of this program are met, with the exceptions of the following lighting technologies:
    • Incandescent
    • T12
    • High pressure sodium
    • Low pressure sodium

How to Participate

Pre-approval is required for the Enhanced Lighting Program.  Contact PSE and complete the application process prior to installation.
  1. Customer and/or contractor completes an Enhanced Lighting Facility Information Form and Lighting Calculation Worksheet.
  2. Submit the signed Facility Information Form and Lighting Calculation Worksheet to PSE for review. The signed Facility Information Form can be sent directly to a PSE Energy Management Engineer or emailed to Customer must sign Facility Information Form!
  3. PSE Energy Management Engineer will schedule a site visit with customer and/or contractor to verify existing conditions.
  4. PSE Energy Management Engineer will finalize Conservation Grant Agreement and send it to the customer for signature and approval. 
  5. Customer returns signed grant, PSE executes and returns copy of the fully executed Conservation Grant Agreement to customer. 
  6. Customer and/or contractor is authorized to install equipment and complete project.
  7. After project completion, customer and/or contractor submits final invoicing to PSE detailing project costs. 
  8. Customer and/or contractor submits signed PSE Lighting Waste Disposal Form and Hazardous Waste "Bill of Lading" and/or Recycling Certificate. (Customer and contractor need to sign PSE Lighting Waste Disposal Form!) 
  9. PSE Energy Management Engineer schedules final site visit to verify as-built fixture types and quantities.
  10. PSE Energy Management Engineer closes out project and payment is issued to customer OR contractor if a signed PSE assignment of funds form is submitted.
