LED Street-lighting Update
Board of Public Utilities March 3, 2012
Pros:
Lower energy consumption
Longer lifespan
Prices have been dropping
White lights (True to Color)
Improved visibility
Good option for new installations
Cons:
Still expensive vs. High Pressure Sodium
Needs a heat regulator to work
Not able to meet lighting levels in a retrofit
What is an LED (Light Emitting Diode)?
Riverside’s LED Programs
2008 - RPU’s began researching LED lamps as a possible
replacement/retrofit
LEDs claim to be more energy efficient than the existing High Pressure
Sodium lamps
LEDs claim to have a longer life span thus reducing maintenance
2009 - RPU began testing this new technology with installation of 14
new LED lights on Overlook Parkway
2010 - RPU received Federal Grant to retrofit 200 existing High
Pressure Sodium (HPS) lamps with LEDs
2012 - RPU may be installing LED lamps in the Wood Streets area

April 2009 - Board approved LED test project
Overlook Parkway selected as testing location due to “gap” in lighting
Construction of new streetlights completed August 2010
RPU’s staff designed this area to meet Illuminating Engineering Society
(IES) Standards using LED lights
Results:
• Installed 14 concrete standards and 14 (157W) LED luminaires
• New LED’s have an estimated 35% energy savings per lamp
• New LED’s have double the life expectancy of existing HPS
• Overall response from the residents in this area has been positive

LED Grant Project
January 2010 - RPU awarded $254,050 of Federal Grant Funds to
install LED luminaires
June 18, 2010 - Board approved retrofit locations:
• Orange Street – State Route 60 to Reid Park
• Martin Luther King Boulevard – Chicago Avenue to Canyon Crest Drive
• Tyler Street – Wells Avenue to Hole Avenue
• Hole Avenue – Tyler Street to La Sierra Avenue
May 2011 - Retrofit completed
Results:
• Replaced 75 existing (100W) HPS with 75 (65W) LEDs
• Replaced 125 existing (200W) HPS with 120 (130W) LEDs
• Estimated 35% Energy Savings per lamp
• Estimated two times the lifespan of a High Pressure Sodium
• Lighting levels on retrofits do not meet IES Standards
• LEDs are not a good option as a retrofit
LED Grant Project
Results of the LED Projects
In a new design, LEDs will save the City 35% in Energy Costs
LEDs have a 10 year warranty from manufacturers
Community response has been positive for the LEDs
Manufacturers are saying the LEDs have a 20 year lifespan – time will tell
The City’s current lighting system was designed to meet the IES Standards
for High Pressure Sodium fixtures.
In 2012, RPU may be using LED lamps for the new streetlight design in
the Wood Streets area.
Plan is to redesign the existing layout to meet the appropriate lighting
levels while saving the City money by going with a lower wattage LED.
New lamp expected to decrease maintenance costs - a major concern in
this area
The Future of LEDs in Riverside
Recommendation
That the Board of Public Utilities receive and file this oral report.
