Change a Light Bulb – Save Some Money

Learn how the simple task of changing your light bulbs can save you money.

Thomas Edison perfected one of the greatest inventions in history, the light bulb. And just like Edison, who continually strived to improved the light bulb, and other has been improving it ever since.

The incandescent light bulb, as great an invention as it is, consumes a lot of power and emits a lot of heat.

The incandescent bulb as we know it is no longer manufactured in the U.S. It has been replaced by a number of different types of bulbs today.

HALOGEN INCANDESCENTS

Halogen incandescents have a capsule inside that holds gas around a filament to increase bulb efficiency. They are available in a wide range of shapes and colors, and they can be used with dimmers. Halogen incandescent bulbs meet the federal minimum energy efficiency standard, but there are now many more efficient options to meet your lighting needs.

CFLS

Compact fluorescent lamps (CFLs) are simply curly versions of the long tube fluorescent lights you may already have in a kitchen or garage. Because they use less electricity than traditional incandescents, typical CFLs can pay for themselves in less than nine months, and then start saving you money each month. An ENERGY STAR-qualified CFL uses about one-fourth the energy and lasts ten times longer than a comparable traditional incandescent bulb that puts out the same amount of light. A typical CFL can pay for itself in energy savings in less than 9 months and continue to save you money each month. A CFL uses about one-third the energy of a halogen incandescent.

CFL bulbs are available in a range of light colors, including warm (white to yellow) tones that were not as available when first introduced. Some are encased in a cover to further diffuse the light and provide a similar shape to the bulbs you are replacing. If you are looking for a dimmable bulb, check the package to make sure you purchase a CFL with that feature.

Fluorescent bulbs contain a small amount of mercury, and they should always be recycled at the end of their lifespan. Many retailers recycle CFLs for free. See EPA’s website for more information.

LEDS

Light emitting diodes (LEDs) are a type of solid-state lighting — semiconductors that convert electricity into light. Although once known mainly for indicator and traffic lights, LEDs in white light, general illumination applications are one of today’s most energy-efficient and rapidly-developing technologies.ENERGY STAR-qualified LEDs use only 20%–25% of the energy and last up to 25 times longer than the traditional incandescent bulbs they replace. LEDs use 25%–30% of the energy and last 8 to 25 times longer than halogen incandescent.

Though changing out your old light bulbs may cost a little extra up front investment, you will recoup the expense in a short amount of time and save money for years to come.
