LED Streetlight Pilot Program


Count on reliable street lighting
Cleveland Public Power (CPP) is committed to providing reliable streetlight service
to the citizens and businesses of Cleveland. CPP owns and maintains approximately
67,000 streetlights. In May 2013, CPP began a pilot program to evaluate the energy
savings, reduced maintenance costs and carbon emission reductions associated with
LED streetlights. LED streetlights offer the possibility of cost savings, lowest energy
consumption and high light output.
Cleveland’s goal is to be a thriving
green city on a blue lake. CPP’s
LED pilot project is a step towards
making this goal a reality.



What are LEDs

LED stands for light-emitting diode. A light-emitting diode is a small electric component that allows the flow of electricity in only one direction and produces light in the process. As a result, they are more efficient, more durable and provide higher energy savings than traditional lighting. Historically, LEDs have been efficient and long lasting as indicator lights in electronics but are rapidly evolving for use as general lighting.

‹‹Before: High Pressure Sodium (HPS) Lighting

In many communities, LED street lighting is increasingly preferred over the traditional high pressure sodium (HPS) street lighting. This is because LED streetlights use 26% less energy and have a life expectancy of 7– 10 years longer than HPS streetlights. However, not all LED lighting is created equal. A poorly designed LED streetlight can start to flicker and offer uneven light. For this reason it is important to select fixtures that meet strict efficiency, quality and life-time criteria. CPP’s LED Streetlight pilot program is designed to ensure that LEDs can meet Cleveland’s standard for roadway illumination while satisfying resident’s safety concerns.

How the pilot program works
To encourage feedback, meetings will be held to allow residents and interested parties an opportunity to comment on the pilot streetlights. There will be surveys available for public comment on CPP’s website, at community centers in the vicinity of the pilot and through Cleveland City Council Ward offices.
CPP will test over one thousand LED streetlights from seventeen different vendors. The goal is to evaluate each vendor’s product and seek the best combination of average savings, high light output, lowest energy consumption and lowest maintenance cost in a streetlight.
How the streetlights will be evaluated
Expected Program Benefits
The LEDs in the pilot will be rated, tested and measured using monitoring equipment, visual observation and lab testing as needed. The testing process will be based on lighting industry standards. To the extent possible, all data will be collected around the same time. To eliminate any vendor bias, each LED streetlight will be assigned an alphabetical designation. Community involvement is an important part of the process.
Based on the success of streetlight pilots in other communities the City of Cleveland and CPP believe selecting the correct LEDs will reduce energy consumption up to 60%, reduce maintenance costs and increase bulb life up to 100,000 hours with an acceptable payback period. In addition, LEDs are compatible with adoptive control monitoring systems and have the ability to dim based on time of day, ambient light or other control parameters.

LED Streetlight Pilot Areas
Three primary locations have been selected for this pilot program one on the eastside, westside and downtown.
Frequently Asked Questions
  

Q: What are LEDs

A: LED stands for light-emitting diode. A light-emitting diode is a small electric component that allows the flow of electricity in only one direction and produces light in the process. As a result, they are more efficient, more durable and provide higher energy savings than traditional lighting. Historically, LEDs have been efficient and long lasting as indicator lights in electronics but are rapidly evolving for use as general lighting. In many communities, LED street lighting is increasingly preferred over the traditional high pressure sodium (HPS) street lighting. This is because LED streetlights use 26% less energy and have a life expectancy of 7–10 years longer than HPS streetlights.

Q: Why are LEDs considered green technology?

A:
LEDs are environmentally friendly in many ways. Unlike HPS lamps LEDs contain no mercury. Also, most LED streetlights are RoHS (Restriction of Hazardous Substances) compliant. This means that the common dangerous substances found in electronic equipment, like mercury, is absent in LEDs or at the least very restricted. The LED streetlight has also been designed to provide more than a decade of near maintenance-free service. On the other hand, the HPS lamp has to be replaced every two years. As a result, it is expected that installing LED streetlights would significantly lower maintenance cost. Other benefits of LEDs:
» No concern over proper disposal of old HPS lamps containing harmful mercury.
» No fuel used and the accompanying pollution to service those fixtures.
» Greatly reduced potential for lane closures and other productivity and
inconvenience related costs associated with maintaining an HPS system.

 

Q: How often will the LED streetlights have to be replaced?

A:
An LED does not burn out like a standard lamp, so individual diodes do not need to be replaced. Instead, the diodes gradually produce lower output levels over a very long period of time. If one LED fails, it does not produce a complete fixture outage.
Q: What is the lifespan of an LED?

A:
The lifespan of an LED is vastly longer than an incandescent, fluorescent or HPS lamp, generally lasting 50,000 hours or longer. LEDs seldom ever burn out. As a result, its life span is measured from the point when it reaches 30% less light output. At 100,000 hours an LED would still be operating, but at a decreased light output. A lifespan of 100,000 works out to:

Hours of Operation      Lifespan in Years
24 hours a day                      11.4 years
12 hours a day                      22.8 years
08 hours a day                      34.2 years
