CFL Myths Uncovered
Myth - CFLs are unsafe.
Truth - CFLs have been thoroughly tested to rigorous safety standards by UL, a third-party product safety certification organization. Consumers can look for the UL Mark and be confident that the CFLs they are using have been tested for safety.
Myth - CFLs are a new, emerging technology.
Truth - CFLs were introduced to market in the 1970s.
Myth - The contents of CFLs are bad for people and the environment.
Truth - CFLs contain a small amount of mercury sealed within the glass tubing - approximately 5 milligrams - a hundred times less mercury than found in a single old-style glass thermometer. No mercury is released when the lamps are intact or in use and if disposed of properly, mercury in CFLs shouldn't be a safety hazard.
Myth - It's difficult to dispose of CFLs.
Truth - Because CFLs contain a small amount of mercury, they should be recycled instead of thrown in the normal trash. To identify local recycling services, consumers can contact their local municipal solid waste agency. Manufacturers and retailers are currently working to expand recycling and disposal options.
Myth - CFLs can't be dimmed or used in three-way fixtures
Truth - Early CFLs did not have dimming capabilities. The technology has evolved, to suit a number of lighting needs. If a light fixture is connected to a dimmer or three-way socket fixture, look for CFLs that specify use with dimmers or three-way fixtures otherwise incompatibilities may occur. As a result, consumers may experience CFLs not starting correctly, flashing, flickering, poor light output or unusual noises. Although there is no clear evidence that there are any safety problems, consumers are likely to become frustrated and give up on using CFLs.
Myth - CFLs are big and ugly.
Truth - CFLs now come in a wide range of shapes and sizes so consumers can easily find one that suits their light fixture and their lifestyle.
Myth - CFLs cast unflattering light.
Truth - Consumers have options with CFLs. Look for a color temperature of 2,700-3,000 Kelvins (or K) to cast a warm glow, and a color temperature of 4,500-6,000K for a cooler light.
Myth - CFLs are expensive.
Truth - While CFLs cost more than incandescent bulbs when purchased initially, their energy efficiency and longevity make up for the cost differential. CFLs use about 75 percent less energy than standard incandescent bulbs and can last up to 10 times longer.
Myth -CFLs can't be used in traditional incandescent light fixtures.
Truth - The design CFLs makes them suitable for use in incandescent light fixtures. To generate light while using the least amount of electricity, most CFLs are constructed in long, thin tubes that are coiled into a spiral. This shape allows CFLs to fit a lighting fixture designed for incandescent bulbs.
CFLs perform best in open fixtures that allow airflow, such as table and floor lamps, wall sconces, pendants, and outdoor fixtures. The best fixtures to use with CFLs are usually found in family and living rooms, the kitchen, dining room, bedrooms and outdoors.
