Installing & Wiring New Outdoor Flood Lights

Flood lights provide a huge amount of light from a single, powerful fixture. They are often used outdoors to cut through the darkness of night. Most flood lights are motion controlled so they only come on once there is something in the line of the light or sensor. This saves energy as well as acting as a first line of defence against unwanted visitors on your property. A common installation site for the lights is under the eaves of the roof.

  1. 1

    Drill a 1.5 inch hole into the underside of your roof’s eave where you want your flood light installed. Use a hole saw to make the hole in the eave.

  2. 2

    Run a 14-2G wire into the hole and push it until most of the length is inside the roof.

  3. 3

    Turn off the electricity running through the house at the breaker box.

  4. 4

    Go into the attic and find the wire you ran through the hole in the eave.

  5. 5

    Connect the wire to the nearest junction box. Attach the plastic casing of the light to the hole. The wire should run through the casing so you can access it once the casing is secured into place.

  6. 6

    Connect the wire from the roof to the electrical connections of the flood light. Push the wiring back through the casing and attach the fixture to housing.

  7. 7

    Insert a light bulb into the fixture and turn the electricity back on.

Tips and warnings

  • Place several floodlights around garages and highly frequented areas for increased visibility.
  • Flood lights are not meant to act as a security system.
