Incandescent light bulbs, including regular or energy-efficient light bulbs
An incandescent bulb is a
type of electric light in which light is produced by a filament heated
by electric current. The most common example is the type you find
in most table and floor lamps. In commercial buildings, incandescent
lights are used for display lights in retail stores, hotels and motels.
This includes the very small, high-intensity track lights used to
display merchandise or provide spot illumination in restaurants. Energy
efficient light bulbs, known as "watt-savers," use less energy than
a standard incandescent bulb. "Long-life" bulbs, bulbs that last longer
than standard incandescent but produce considerably less light, are
not considered energy-efficient bulbs. This category also includes
halogen lamps. Halogen lamps are a special type of incandescent lamp
containing halogen gas to produce a brighter, whiter light than standard
incandescent. Halogen lamps come in three styles: bulbs, models with
reflectors, and infrared models with reflectors. Halogen lamps are
especially suited to recessed or "canned fixtures," track lights,
and outdoor lights.
