Enlightening facts about Calgary's streetlights

The City of Calgary aims to provide appropriate lighting levels for safe pedestrian and vehicular movements at a reasonable cost. However, our streetlight infrastructure is aging, meaning many lights are now in need of repair or replacing.

To help put in perspective this unusually high number of lights currently requiring maintenance, we've had a 48 per cent increase in streetlight service requests from the first quarter of 2011 to the first quarter of 2012 (from roughly 2300 to over 3400).

Some maintenance items are weather dependent and therefore have to be scheduled for spring or summer, so we ask that Calgarians be patient as we tend to our city's streetlights as best we can.

Did you know:
  • The City's streetlight circuits are controlled by approximately 7,000 photoelectric sensors that sense the amount of ambient light in its surrounding area.
  • Old streetlight fixtures are disassembled and the components – glass, steel, aluminum – are recycled. Some parts are even used for crafts. The old glass refractors have been used as pots and the ceramic arc tubes for sharpening knifes.
  • The City of Calgary was the first in North America to undertake a complete retrofit of approximately 37,500 residential streetlights (2002 - 2005), switching to lower-wattage EnviroSmart fixtures.
  • Depending on the location of the streetlight, they could be maintained by private land owners, ENMAX, Alberta Transportation, or the Calgary Downtown Association.
To report a streetlight that needs fixing, please call 3-1-1 or connect with them online. For more information on The City's streetlights, visit our streetlight FAQ page.
