Outdoor lighting is an important safety feature for the 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. Compact
fluorescent lights are the perfect choice for outdoor lighting. Not only can they save you
money, they are also energy efficient. Compact fluorescents have to be changed
infrequently, which makes them a good choice for places where changing a bulb might be
difficult. 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 business. Illuminate pathways
with small ground level moon lamps, or light your front steps or entry way with post
lanterns. When planning outdoor lighting, make sure whatever you
choose doesn't light up your neighbor's property 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
(HID) ighting. 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 be 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 a stake on which the fixture is
mounted into the ground. Larger, brighter PV lights are also available, but these may
require additional light panels. Often these additional panels can blend attractively with
your buildings's architecture.
