Today, there are several light bulb options available in stores, including light-emitting diodes (LEDs), compact fluorescents (CFLs), and halogen incandescent bulbs; which are much more energy efficient than standard incandescent bulbs, so they save you energy and money.
In the past, when nearly everyone filled their homes with incandescent bulbs, brightness was measured in watts. Since the introduction of energy-saving bulbs, this is a less useful measure of brightness, as new bulbs use a lot less power to produce the same amount of light. The next time you’re shopping for lightbulbs, you can choose bulbs for the brightness you want by comparing lumens instead of watts. The higher the number of lumens, the brighter the lightbulb.
To help you shop for the right lightbulb, you’ll find an easy-to-read product label on the packaging that lists the bulb’s brightness measured in lumens), an estimated yearly energy cost, and other qualities like the bulb’s lifespan and light color/appearance, which ranges from warm yellow to cool blue.
What’s the Difference?
An LED is a type of solid-state lighting that uses a semiconductor to convert electricity into light. L EDs are currently available as replacements for 40W, 60W, and 75W standard incandescent bulbs. ENERGY STAR-qualified LEDs use only 20%–25% of the energy and last 15 to 25 times longer than the standard incandescent bulbs they replace. LEDs use 25%–30% of the energy and last 8 to 25 times longer than halogen incandescents.
CFLs combine the energy efficiency of fluorescent lighting with the convenience of incandescent fixtures and use about one-fourth less energy than standard incandescent bulbs. An ENERGY STAR-qualified CFL lasts 10 times longer than a comparable incandescent bulb that puts out the same amount of light. A CFL also uses about 33% of the energy of a halogen incandescent. Note: Fluorescent bulbs contain a small amount of mercury, so they should always be recycled at the end of their lifespan, rather than just thrown away.
Halogen incandescents have a capsule inside that holds gas around a filament to increase bulb efficiency. Halogen incandescents last 2 to 3 times longer than standard incandescent bulbs and are capable of producing brighter light than standard bulbs. While halogens are more efficient than standard incandescent bulbs, and they use similar technology as LEDs and CFLs, they are less efficient than both LEDs and CFLs.
Choosing the right kind of lightbulbs for your home can have a significant impact on your energy consumption. With energy-saving lightbulbs, you can light your home using the same amount of light, while using a lot less energy.
