LEDs light up Calgary communities this summer

The City is illuminating five communities in Calgary with 2,500 new energy-efficient LED streetlights this summer.

GE Evolve ERS1 LED fixtures
Altadore, Douglasdale, Marlborough, Tuxedo Park, and Brentwood are part of the first phase of an initiative focused on changing the existing High Pressure Sodium (HPS) street lights to energy efficient fixtures. LED light installations started in the community of Altadore, and will be ongoing throughout the summer and early fall. In a two-phased project, The City plans to eventually undertake a city-wide retrofit of approximately 80,000 fixtures.

“This is the first step in The City’s larger vision of providing Calgarians with smart, sustainable, and cost-effective infrastructure,” said Barry Poon, Acting Director of Roads. “The LED technology will not only reduce electricity use and lower maintenance costs, but will also provide better quality lighting for our communities and roadways.”

Benefits of LED street lighting
  • Reduces electricity consumption
  • Makes objects appear clearer and more defined
  • Reduces the amount of “spilled” or wasted light, ensuring light is focused on roads and sidewalks, where it is most useful to drivers and pedestrians

    2. What colour light will the new lamps emit? Will it be the same colour light as the current lamps? Or will it be that "cold" white light that you sometimes see on other LED based bulbs?

      1. The potential impacts of blue/white light associated with LEDs were evaluated by our Roads department. The LED technology used in residential areas in Calgary will use a “warmer” light, meaning that exposure to blue light will be minimal.

    3. What do you do with the old lights? How much will the project cost and how long until you recover the costs due to decrease electrical cost and less frequent replacement of bulbs?

      1. Here is a three-part answer to your questions:

        1. The old lights will be recycled.
        2. The cost for phase 1 (2,500 lights in 5 communities) is $1.2 million. Phase 2 (80,000 lights city-wide) will be $32 million (Phase 2 was just approved at Council this morning).
        3. We are expecting a $5mil/year savings in electricity costs, so the payback will be realized in just over 6 years. This doesn’t take into account maintenance costs, but we are expecting these to decrease as well because LEDs are known for their longevity.

      2. I for one would like to see the new lights as we have a couple of lights that glare into our house at night.

        I like the fact the City of Calgary is always improving our way of life. Sure, it will cost money, but the replacement life and energy savings will make up for it.

    4. 2003, you replaced the old lights to the Sodium lights, to save money, but they were dark, now again we are placing lights to save money, When will we stop replacing lights every time some idea comes and it supposedly saves money?

    5. LED street lights! It's a great energy saving and Eco friendly initiative. LED utilization will surely save energy and would generate less heat.

    6. LED lights are wonderful to use because they are so versatile and can be used for a wide variety of purposes. It's great that using LED lights as streetlights will save the city energy and increase the amount of light. Thanks so much for sharing!
