HPS_to_LED_4000K_Equivalents.pdf

This is a technical reference document prepared by the City of Pasadena Department of Public Works that provides HPS to LED fixture equivalency specifications for street and safety lighting upgrades. The document establishes approximate wattage and lumen equivalencies between traditional high-pressure sodium (HPS) luminaires and three LED cobra head fixture manufacturers: GE Evolve, Lumec RoadFocus Plus, and EOI Compass. The equivalency chart covers HPS wattages ranging from 70 watts to 250 watts, with corresponding LED models producing comparable or superior lumen output at significantly reduced wattages. For example, a 70-watt HPS fixture is equivalent to approximately 22-24 watt LED alternatives producing 2,800-3,345 lumens, while a 250-watt HPS fixture corresponds to 110-154 watt LED models producing 16,000-20,526 lumens. The document includes specific ordering information and model numbers for each fixture option across all wattage tiers.

The specification document establishes several key requirements for all LED luminaire procurements: finish color must be specified as needed, each installation location requires individual analysis to meet Illuminating Engineering Society (IES) standards, all luminaires must include identifying wattage stickers, and suppliers must provide a 10-year standard warranty. The document was updated April 16, 2025, and prepared by E.J. of the Department of Public Works, indicating this reference material supports the City of Pasadena's broader LED Street and Safety Lighting Upgrades project designed to replace induction and HPS luminaires along major corridors with modern LED cobra head fixtures and photocell controls.
