How much does motion-sensor exterior lighting cost to install in Calgary?

Motion-sensor exterior lighting installation in Calgary typically costs $175 to $350 per fixture, including the fixture, wiring connections, and labour. If you are replacing an existing exterior light with a motion-sensor model on the same junction box and circuit, the cost drops to $130 to $225 per fixture since no new wiring is needed. The fixture itself ranges from $40 to $200 depending on quality, light output, detection range, and features.

For a typical Calgary home, homeowners usually install motion-sensor lights at two to four key locations: the front entry, the back door or patio, the garage or driveway, and a side entrance. A full four-fixture installation replacing existing lights runs $500 to $900 total, while adding new motion-sensor fixtures where none existed (requiring new wiring, junction boxes, and circuits) costs $700 to $1,400 for four locations. Most electricians offer per-project pricing that is more economical than individual fixture quotes.

Choosing the right motion-sensor fixture for Calgary's climate requires attention to several factors. The fixture must be rated for at least -40 degrees Celsius operating temperature — this is non-negotiable for reliable winter performance. Many motion sensors use passive infrared (PIR) detection, which senses heat differential between a moving person and the ambient background. In Calgary's extreme cold, the temperature difference between a warm body and -30 degree air is dramatic, which actually makes PIR sensors more sensitive in winter. However, cheap sensors can become sluggish or unresponsive in extreme cold due to poor component quality. Invest in fixtures from established brands like RAB, Lithonia, Heath Zenith, or Ring that specify cold-weather operation.

Calgary's chinook winds create a unique challenge for motion sensors. Rapid temperature swings can cause false triggering as warm air masses move across the sensor's detection zone. Adjustable sensitivity settings help — set the sensitivity lower during chinook season (typically December through March) to reduce false activations. Also consider the detection range and angle. A sensor with a 180-degree detection arc and 12-metre range covers most residential applications, but fixtures mounted under deep eaves or soffits may need a narrower, longer-range sensor to detect motion at ground level effectively.

LED motion-sensor floodlights are the standard choice for Calgary installations. They provide instant-on illumination (no warm-up time like old HID security lights), draw 15 to 30 watts compared to 150 to 300 watts for halogen floodlights, and last 25,000 to 50,000 hours. Given Calgary's long winter nights — up to 16 hours of darkness in December — energy-efficient LED fixtures keep electricity costs manageable. Dual-head adjustable floodlights provide the most coverage per fixture for driveways and backyards, while wall-mounted lantern-style motion lights are more appropriate for front entries where aesthetics matter.

All exterior electrical fixtures must have GFCI protection as required by the Canadian Electrical Code, and new installations require an electrical permit from the City of Calgary. A licensed electrician ensures proper weatherproof connections, correct wire type for outdoor use, and code-compliant GFCI protection.
