Replace Outdoor Lights with LEDs
GOV-06
Measure
Efforts for the measure or action have begun but not all work has been completed.
With this measure, the County intends to reduce energy related emissions by replacing all high-pressure sodium streetlights and all other outdoor lights with light-emitting diode (LED) fixtures.
This measure has no incremental GHG reductions because it reduces the County government’s electricity usage, and it is assumed that by 2030 emissions from electricity will be zero due to GHG-03: Support SMUD in the implementation of the 2030 Zero Carbon Plan.
Actions
Action GOV-06-a
Replace remaining 2,200 high-pressure sodium (HPS) and mercury-vapor (MV) streetlights with LED technology.
Action GOV-06-b
Perform an audit of existing outdoor County lighting, including all County-owned and -managed buildings, facilities, parks, and properties.
Action GOV-06-c
Replace outdoor lighting with LED technology at all County-owned and -managed buildings, facilities, parks, and properties, where LED technology is not currently in place.
Status of Implementation
The Department of Transportation maintains approximately 24,000 streetlights for illumination County-wide. 22,300 streetlights have been converted to LED lamps through the annual streetlight replacement program. There are approximately 1,700 replacements to complete in the next three years at the rate of 550 lamps per year.

Objectives
Replace all 2,200 remaining high-pressure sodium County-managed streetlights with LEDs by 2030, and all remaining County-managed outdoor lighting with LEDs by 2045.
