What Is the Difference Between Fluorescent Light Bulbs & Regular Light Bulbs?

Compact fluorescent light bulbs are beginning to replace regular light bulbs, also known as incandescent light bulbs. Regular lights generally have a bulb shape, while fluorescent bulbs are often shaped as coils.

Function

Fluorescent light bulbs can last about 10 times as long as regular light bulbs, which reduces the number of light bulbs that end up in landfills.

Significance

Compact fluorescent bulbs do contain a trace amount of mercury, which makes them worse for the environment than regular light bulbs.

Cost

Fluorescent bulbs are more expensive to purchase than regular light bulbs but can save you about $30 in energy costs over the life of the fluorescent bulb.

Considerations

Regular light bulbs are compatible with more dimmers than fluorescent bulbs, and most fluorescent bulbs cannot function with motion-sensing light sockets.

Effects

Fluorescent bulbs give off up to 70 percent less heat than regular bulbs, according to National Public Radio, which makes them safer and reduces air-conditioning costs.
