Decide where you need more light at night. Lights installed near home entrances or garage doors are ideal, both for car and foot traffic. If you have a utility shed in a dark corner of your property, install a light there to deter any potential intruders looking for an opportunity. Or light up a walkway with a motion-activated floodlight that snaps on when someone approaches. Many floodlight models have either motion-activated sensors, or they have light-activated sensors that turn the lights on when the sun goes down.
Use a ladder to reach the location where you will install the floodlight (the fixture should be installed high—for example, near the roof—to provide effective coverage) and mark it with a piece of tape or a marker or pen.
If you have a large area that requires substantial amounts of light and you want to illuminate it with a single fixture, a high-pressure sodium or metal halide security light is appropriate. A 70-watt sodium security light will illuminate more than 8,500 square feet, provide 6,300 lumens of light, and last up to 12 times longer than a standard incandescent floodlight. Most sodium and metal halide security lights come with a built-in photo control and the light will automatically turn on at dusk and turn off at dawn with no timers or switches.
LED security lights are a good option because they use less electricity and so are more energy efficient, and have a longer lifespan than standard bulbs.
