Flood lights are a deterrent against burglars and other criminals who would target your house. They can also illuminate pathways and highlight danger spots around the house, such as the pool and flights of stairs. Adding motion sensors to these flood lights saves electricity and can startle burglars approaching a dark house. Careful positioning of the motion sensors can cut back on false triggers, such as animals and leaves.

Instructions

  1. 1

    Select a location for the lights. Target dark corners of the house and yard if your intent is to beef up security around your house, along with possibly entryways such as windows. Install the lights between 6 and 10 feet above the ground.

  2. 2

    Turn off power to the installation area using the main breaker box.

  3. 3

    Don safety gear, including thick gloves, protective glasses and a dust mask.

  4. 4

    Locate the closest electrical conduit, unscrew the plate and attach the motion sensor's extension box. This is your flood light's power source; the extension box is the base from which you will thread the wires to the light.

  5. 5

    Mount a metal conduit from the extension box to the ceiling. The conduit is like a small tunnel that the wires travel through. Attach more conduit along the edge of the ceiling until you reach the point where you will attach your light. Attach support hangers for the conduit every 12 inches.

  6. 6

    Attach a junction box to the ceiling. This will serve to protect the wires as they connect to the outside wires.

  7. 7

    Drill a hole through the wall. Thread your wires through the hole from the inside of the house to the light's electrical box. Connect the wires with the corresponding colours. So, for instance, the red wire will connect with the red wire, the blue with the blue and so on.

  8. 8

    Screw in the light bulbs for your light and set the timer for how long you want the light to stay lit when it is triggered. Limit the range of the motion sensor with duct tape if you want; this cuts down on false triggers. Attach the light to the wall.

Tips and warnings

  • Always make sure the power is off when working with electrical wires.
