Light your home or business for less—with high-quality, low-cost CFLs in many shapes and styles.
With a lifespan as long as 10 years and a 99¢ starting price, CFLs are a practical way to save money on home or business lighting. Modern CFLs screw into standard sockets and consume 70% less energy than incandescents. They turn on instantly, offer a wide range of color temperatures, and never flicker. Because they contain mercury, it’s important to dispose of CFLs properly when they break or need replacing.
Compact Fluorescent Light bulbs (CFLs) are small, coiled versions of fluorescent tubes, a technology that dates to the 1800s. While incandescents produce light by heating a tungsten filament, CFLs send an electrical charge through gas vapor, making the tube glow. Thanks to an integrated ballast (the part that controls current), modern CFLs are flicker free and work in any standard socket — which makes them an easy, attractive, low-cost option.
CFLs give you high-quality, affordable, efficient lighting both indoors and out. For home and business, they’re used anywhere you’d find an incandescent: downlights, track lights, lamps and sconces, task lights, outdoor floods, and driveways. Modern CFLs also offer a broad choice of colors on the Kelvin scale, from warm to cool to daylight.
In addition to standard spirals, CFLs come in dimmable and three-way versions (typically in soft-white light). All three look alike, so check the box to make sure you’re buying the right one for your fixture. Spiral CFLs fit almost anywhere you use an incandescent, though for tight spots you may need a smaller “A-style” bulb. Tip: dimmable CFLs give more consistent soft-white light than incandescents.

Decorative CFLs house their spiral coils in a variety of coverings. Globes are ideal for bathroom vanities and pendants. Candelabras are used in chandeliers, ceiling fans, sconces, and covered outdoor lights. And A-style bulbs, wherever you’d find a traditional incandescent (and for any spot where a spiral may not fit). Tip: because they’re encapsulated, decorative CFLs take a few seconds to reach full brightness.
Reflector CFLs give even, directional light indoors — perfect for track or downlights. For use in recessed lighting, make sure your packaging reads “suitable for enclosed fixtures.” Outdoor reflectors are bigger, and should be labeled “damp location approved.” Also designed for rain and snow, post-style CFLs are ideal for porch lamps and driveway lights. Tip: check with the manufacturer to see if outdoor CFLs will work with your timers, photocells, and motion sensors.
