    San Diego converts from sodium vapor lamps to fluorescent induction lamps

    Energy Saving Projects
    Citywide Broad Spectrum Street Lighting Retrofits

    Background

    The project will provide upgraded street lights with better illumination with no additional cost to City taxpayers. Funding is provided by a federal stimulus grant, and a low interest bond and loan. The energy savings exceed the financing debt service, thereby "paying" for the upgrade.

    BEFORE: Current high-pressure sodium vapor lamps cast yellow glow.

    AFTER: New induction lamps provide better color rendering.
    Project Overview

    The $16 million citywide project will convert more than 36,000 existing sodium vapor street lights to broad-spectrum induction lighting. The city currently has 50,000 street lights.

    Broad-spectrum lighting is a whiter light and more like sunlight. The current street lights cast a yellow glow.
    Estimated annual savings of $2.2 million.
    16 million annual kilowatt-hours in energy savings, equal to the amount of energy used by 2,540 homes.
    Eligible for $1.2 million in rebates from SDGE®

    The project will be operated within the public roadway and not on private property. The contractor, Southern Contracting Co., is responsible for traffic and control to protect public safety within the project areas and is responsible to keep the area as clean as possible from dirt and dust.
    Construction Schedule

    Southern Contracting Co. began retrofitting street lights mid-September 2011 and finish early 2013. Approximately 2,600 lighting fixtures will be replaced each month.
