There are many ways to save money on your lighting bill.
A number of suggestions in this section are simple and inexpensive. More complicated
or costly modifications to your lighting systems may have less complicated alternatives
and should be thoroughly analyzed before proceeding.
Also, keep in mind that not only do different tasks require
different light levels (Table 12), but some workers
in general require more light to do the same tasks as other employees.
When thinking about your particular needs, keep in mind
that lighting energy can be wasted in three ways:
Inefficient Light Sources
Some types of lamps and fixtures are better than others at converting electricity
into illumination (see "Light Sources").
Transmission Loss
Light is diffused over distance and reduced by dirt, dust or other obstructions.
Overlighting
You may simply have more illumination than you need, or you could get the
same effect using sunlight, reflectors or a lighter interior color scheme.
