Cost to Install a Motion Sensor Light
Installing a motion sensor light means removing an existing fixture or wall switch, connecting a sensor-equipped replacement to the house wiring, and testing it after power is restored. It is a hard electrical job because it involves the service panel, wire connections, and adjustment of the sensor's time and light-sensitivity (lux) settings.
Common reasons homeowners do this job
- Replacing a worn or damaged existing light fixture
- Replacing a worn or damaged wall switch
- Upgrading an existing light fixture with motion sensing
- Upgrading an existing wall switch with motion sensing
- Installing a motion sensor unit at a selected location
DIY or call a pro?
A licensed professional should install a motion sensor light because the work involves the electrical service panel and electrical wiring. Power must be turned off at the circuit breaker and confirmed off with a non-contact voltage tester before any wires are touched. If there is uncertainty about the wiring, service panel, or compatibility of the existing wiring, hire a licensed electrician.
Frequently asked questions
- Is installing a motion sensor light a DIY project or an electrician job?
- Hire a licensed electrician for this work. It involves the electrical panel and house wiring, so power must be shut off at the breaker and verified off with a non-contact voltage tester before any wiring is handled.
- Which factors can raise the price of a motion sensor light installation?
- The price can increase with job size, labor time, and materials. A small job may also carry a minimum or trip charge.
- What should be verified before selecting a motion sensor fixture or switch?
- Identify the intended location and verify that the existing wiring is compatible with the new motion sensor unit. For a kit with specific spacing or controller-placement requirements, measure the area as well.
- What tools are used to install a motion sensor light?
- The work uses Phillips and flathead screwdrivers, a non-contact voltage tester, wire cutters or strippers, and pliers. A cordless drill may also be needed.
