How much does commercial LED retrofit lighting cost in Calgary?

Commercial LED retrofit lighting in Calgary typically costs $75 to $300 per fixture, depending on the fixture type, whether you are re-lamping existing fixtures or replacing them entirely, and the scale of the project. For a standard 2,000-square-foot office or retail space with 30 to 50 fluorescent troffers, a complete LED retrofit runs $3,000 to $12,000 including fixtures, labour, and disposal of old ballasts and lamps. Larger commercial spaces — warehouses, retail floors, parking garages — can run $15,000 to $50,000+ but often see the fastest payback due to high existing energy consumption.

There are two main approaches to commercial LED retrofits. The first is a retrofit kit, where your electrician installs an LED panel or LED tube assembly into your existing fluorescent troffer housing. This approach costs $75 to $150 per fixture installed and is fastest — a 50-fixture office can often be completed in a single day. The existing housing stays, but the fluorescent tubes, ballasts, and starters are removed and replaced with LED drivers and panels. The second approach is a full fixture replacement, where the old fluorescent troffers are removed entirely and replaced with modern LED flat panels or architectural fixtures. This costs $150 to $300 per fixture installed but delivers better light quality, a cleaner appearance, and longer fixture life. For high-bay warehouse and industrial lighting, LED high-bay fixtures cost $200 to $500 per fixture installed, replacing old metal halide or high-pressure sodium fixtures that draw 400W to 1,000W each.

The energy savings in Calgary's commercial context are significant. A typical 4-foot fluorescent troffer with two T8 tubes and a magnetic ballast draws about 72 watts. An LED replacement panel draws 30 to 40 watts for equal or better light output — roughly a 50% reduction. For a 10,000-square-foot office with 150 fixtures running 10 hours per day, that translates to approximately $2,500 to $4,000 in annual energy savings at Calgary's commercial electricity rates. Most commercial LED retrofits in Calgary pay for themselves within 2 to 4 years through energy savings alone, and LED fixtures last 50,000 to 100,000 hours compared to 20,000 hours for fluorescent tubes, eliminating the ongoing cost of lamp replacements and maintenance labour.

Calgary's climate creates additional incentive for LED retrofits. Fluorescent lamps are notoriously unreliable in cold temperatures — parking garage and exterior fluorescent fixtures in Calgary often flicker, dim, or fail to start during cold snaps when temperatures drop below -20 degrees Celsius. LEDs perform exceptionally well in cold conditions and actually become more efficient at lower temperatures, making them ideal for Calgary's parking garages, loading docks, exterior building lighting, and unheated warehouse spaces. The UV resistance of quality LED fixtures also holds up better against Calgary's intense high-altitude sunlight for exterior applications.

An electrical permit is generally not required for a like-for-like lighting retrofit where you are replacing existing fixtures on existing circuits without adding new wiring or circuits. However, if the retrofit involves adding new circuits, changing circuit layouts, or installing lighting controls and dimmers on new wiring, a permit from the City of Calgary is required. Your electrician should advise on permit requirements for your specific project. Ensure they carry WCB Alberta coverage and dispose of old fluorescent tubes and ballasts properly — fluorescent tubes contain mercury and must be recycled through approved facilities in Alberta.
