Coquitlam launched a five-year program in early September 2018 to convert about 9,500 streetlights across the city to energy-efficient light-emitting diodes (LED). About 1,900 lights are being installed in fall 2018, and a similar number will follow each year to 2022.
Benefits of LEDs
Compared to the existing high-pressure sodium and metal halide streetlights, the new LED lights:
Last up to 20 years (four to five times longer)
Will consume 57 per cent less energy (a savings of about $446,000 per year)
Will cost about half as much to maintain
The City expects to recoup the $6.5-million project cost in 14 to 17 years and save $3.8 million over 20 years.
2016 to 2017 Pilot Project
Coquitlam conducted a pilot project in 2016 and 2017 before making the decision this year to convert all streetlights to LED. The City’s project does not include about 2,000 high pressure sodium (HPS) streetlights attached to wooden power poles, which BC Hydro owns and manages.

What to Expect
Crews may be seen around the city installing the new lights. Motorists, pedestrians and residents may notice improvements to the street and sidewalk lighting as well as reduced light pollution.
The new lights will provide as good, or better, roadway lighting while reducing the amount of light pollution in the sky or spilling onto private property.
Cobra Style Lights
In total, about 3,500 existing cobra-style lights (with arched necks and flat heads) and 4,900 post-top lights will be converted to LED cobra-style fixtures, which focus the light down towards the sidewalk and street.
Post Top Lights
About 1,100 decorative post-top lights in Burquitlam, Austin Heights, Maillardville and City Centre will be converted to LED fixtures using special kits. These kits cost three to four times as much as cobra-style lights, so are being used strategically in core pedestrian areas to preserve the aesthetic look of the decorative fixtures in those unique areas.
