For Your Home
Outdoor Security Lighting

Outdoor lighting is an important safety feature for your home or workplace. Well-lit properties are less likely to be burglarized. They are also unlikely to be the scene of accidents caused by dark pathways, where people might easily trip and fall. Outdoor lighting can also beautify a home, thus increasing its value. Compact fluorescent lights are the perfect choice for outdoor lighting. They can save you money, and they are also energy efficient.

One note of caution—if you live in a cold climate, be sure to buy a compact fluorescent lamp with a cold-weather ballast. Devices such as timers or photocells can be used to turn lights on and off at appropriate times.

To save energy and money, don't burn lights all night long, except in areas with actual all-night use or with extreme security concerns. For most security purposes, motion sensors can detect intruders and turn on lights when needed. Special outdoor lighting fixtures can help to beautify your home or business. Illuminate pathways with small ground level moon lamps, or light your front steps or entry way with post lanterns. When planning outdoor home lighting, make sure whatever outdoor lighting you choose doesn't light up your neighbor's yard as well as your own. Be considerate and ensure that your lights stay on your property. Good low-glare options are linear "tube lights" and fiber-optics. These lights can light the way for pedestrians without illuminating an entire area. Cut-off fixtures, shades, or highly focused low-voltage lamps are also useful in avoiding spillover.

Just as fluorescent lighting has improved in recent years, great advances have been made in high-intensity discharge—or HID—lighting. Primarily used outdoors and for large areas like streets or parking lots, there are three kinds of HID lights: mercury vapor, high-pressure sodium, and metal halide. All require ballasts, much like fluorescent lighting. All take several minutes to warm up, so they are better suited to areas in which lights stay on for long periods of time. Mercury vapor lights have been the most common type of HID, but they are quickly being replaced by the newer, more efficient high-pressure sodium and metal halide lamps. High pressure sodium lights produce the most light—the most lumens—per watt, although the light has a yellowish tinge. Metal halide lights are less efficient but produce a whiter, more natural light.

You can also use solar energy to power outdoor lighting. During daylight hours, a photovoltaic (PV) panel generates electricity that is stored in a battery in most of the low-power light fixtures. These lights can be turned on manually, they can equipped with light-sensing controls that turn them on automatically at dusk, or they can be activated by motion detectors. Most of the lower-priced models on the market do not produce a great deal of light—they're definitely not reading lamps—but they are very useful to light paths and steps around the yard. Using PV-powered outdoor lights is an attractive alternative if your site is over 200 yards from the utility grid, or if you don't want to run a power line through a site. PV power is low-maintenance and very reliable, and installation is often as easy as pushing into the ground a stake on which the fixture is mounted. Larger, brighter PV lights are also available, but these may require additional light panels. Often these additional panels can blend attractively with your home's architecture.
