Standard Incandescent Bulbs

Standard Incandescent Bulb

The standard incandescent bulb is the original and most common type of bulb used in the home. Incandescent bulbs have a low initial cost, are compact and produce a warm colour tone. However, they are not very energy efficient, as only approximately 5 to 8 percent; of the energy that goes into the fixture produces light, while the rest is dissipated as heat.

Long-Life or Extended-Life Incandescent Bulbs

Long-life or extended life incandescent bulbs have a longer rated lifetime (in hours) than regular bulbs. However, they produce up to 30 percent less light while using the same amount of energy. Bulbs with a higher than normal voltage rating are also available (typically 130 V instead of the standard 120 V). These bulbs, which are intended for use where the electrical supply voltage fluctuates, such as in some rural areas, are less efficient than standard incandescents.

Reduced-Wattage Incandescent Bulbs

Reduced-wattage incandescent bulbs, often called energy-saver bulbs, are a slightly more energy-efficient version of the regular incandescent bulb. They save energy primarily by producing slightly less light at a lower wattage. They are not nearly as efficient as compact fluorescent lamps but are compatible with dimmers, work well outdoors, can be used in any light fixture that takes a regular incandescent bulb, and cost less to buy than fluorescents.
