LED Street Light Conversion Project

Ultra-efficient LED fixtures will replace 18,500 City-owned, high-pressure sodium cobra-head style street light fixtures.

6

Improved Lighting

• LED’s produce a neutral white light that’s similar to the natural light of the moon

• Better visibility

7

Less Energy LED’s consume up to 50% less energy than existing lamps

Less Money • Existing lamps burn out

after 4 years • LED fixtures are

maintenance free for 15 to 20 years

8

Innovation!

• Remote monitoring and adjustment

• Targeted repair

9

Coming to a street lamp near you …

… or at least not too far away

• Conversion to LED’s scheduled to begin in one to two years

• Installation will take about 14 months

SFPUC Street Light Wireless Control Pilot Project

Identify and test leading LED street light wireless control and communications products.

11

Test Locations

• Washington between Arguello and Presidio • Irving between 6th and 24th • Pine between Davis and Grant, and California

between Sansome and Kearny

12

Wireless Controls for LED Street Lights

• On/off scheduling • Failure detection and data collection • Luminaire grouping • Lumen depreciation adjustment

13

… and there’s more!

• Electric vehicle charging stations data transmission

• Municipal electric meter reading • Street surveillance • Street parking monitoring devices • Traffic monitoring • Traffic signal control • Pollution monitoring • Adaptive lighting 14

Adaptive Street Lighting Management

The practice of adjusting lighting power and output as environmental conditions change.

15

Benefits of Adaptive Lighting

Adaptive lighting – making the most of LED street lights:

• Reduced light pollution = darker night skies • Reduced light into people’s homes • Increased energy savings • Streets are appropriately lit based upon

pedestrian and vehicular usage

16

Why a Pilot?

• Test technology before purchase • Assess public experience with adaptive lighting

practices • Develop effective adaptive lighting strategies • Determine where, how and when adaptive

lighting is appropriate for City streets
