La Verne LED Street Light Conversion Project Frequently Asked Questions

1. What kind of street lights does La Verne currently use?

The street lights currently used in La Verne are High Pressure Sodium (HPS) lights.  While HPS is one of the most common street light technologies across the country, it has several drawbacks.  HPS street lights are not very energy efficient, cast an orange light under which it is difficult to see color, and tend to produce light that is not of optimal viewing quality.

2. What are LED street lights?

Light Emitting Diodes (LED) are a technology that has been used in solid state lighting for decades.  More recently, LED technology has advanced to street light applications. LED street lights are extremely energy efficient, have long life spans, and produce a better color and quality of light than typical HPS street lights.

3. What color of light are LED street light fixtures?

Contrary to the orange light that HPS fixtures produce, LED street light fixtures are a cooler, white light under which it is easier to see true colors.  HPS lights have a color temperature of 2,200 Kelvin while La Verne’s new LED lights will have a color temperature of 3,000 Kelvin.

4. Why do the new LED fixtures appear to be dimmer?

Although the new LED fixtures produce a different looking light than the HPS fixtures they replaced, they are not actually dimmer.  HPS fixtures tend to produce a bright spot directly underneath the fixture, whereas LEDs create a more even pool of light across the ground or roadway.

5. Why is La Verne doing an LED street light conversion project?

La Verne is interested in reducing its energy consumption and maintenance costs associated with street lighting.  Installing LED street light fixtures will save energy, require less maintenance, and will provide citizens with better light quality on streets and roadways.

6. How many street lights is La Verne replacing with the LED street light conversion project?

This project will replace approximately 2,000 street lights throughout La Verne, most of which are standard street lights (called “cobra heads”).

7. How much will La Verne likely save when it upgrades to LED street light fixtures?

The project is expected to save La Verne over 700,000 kilowatt hours and over $150,000 in energy costs in the first year after the project is implemented.

8. How long will the project last?

The installation is scheduled to begin in March 2019 and will complete in April 2019.

9. What are the benefits of the LED street light fixture project?

The benefits of this project in La Verne include: 

  • Reduced energy consumption resulting in energy cost savings and decreased greenhouse gas emissions.
  • Reduced maintenance costs.
  • Better visible light for La Verne’s citizens.

10. What is La Verne doing with all of the street lights it is removing?

The existing HPS street lights will be recycled in accordance with all federal and state environmental guidelines.
