CFL Bulbs: An overview
Compact fluorescent bulbs—usually referred to by the initials “CFL”— have come a long way. Early versions were expensive (as much as $15 apiece) and plagued with problems (they appeared dim, flickered, didn’t come on instantly and burned out sooner than promised).
But that was then. New technology has solved most of the old problems. Today, using CFLs is one of the easiest and most effective ways to save money on energy. It’s as easy as screwing in a bulb and flipping a switch. Many CFLs can be purchased for about $3 or less, and some utility companies offer discounts or rebates to customers who buy them.
How to choose CFL bulbs
Answer: Look at the lumen rating, not the bulb wattage, to compare real light output. Then buy a CFL with 20 percent more lumens than the incandescent bulb you want to replace has. For example, to replace a 60-watt incandescent bulb that has 870 lumens, buy a CFL with at least 1,050 lumens. If you follow wattage guidelines on the package, you may not be satisfied with the light output. Be wary of CFLs that don’t list the lumens on the packaging. Their claims that the light output matches a certain incandescent wattage are sometimes misleading or wrong.
Another reason you need more lumens is that a CFL will dim over time. It will lose 20 to 25 percent lumen power after 4,000 hours (40 percent of a CFL’s 10,000-hour-rated life). Incandescent bulbs also lose lumens, but the life of these bulbs is extremely short compared with that of CFLs.
Best (and worst) places to use CFL Bulbs
Question: Are there some places where using a CFL makes more sense than others?
Answer: Since many CFLs last up to 10 times as long as incandescents, consider placing CFLs in difficult-to- reach fixtures. It may mean climbing the ladder once every five years instead of every year. It also makes sense to use CFLs in light fixtures that are continuously “On” more than three hours per day.
CFLs save energy in any location, but there are some circumstances that can reduce their lifespan:
Frequent on-off switching, as in a hallway.
Excessive vibration near doors or stairways.
High-humidity areas such as a damp basement.
A CFL that’s not rated for use in an enclosed light fixture might burn out prematurely if enclosed.
Payback: How long? How come?
Answer: Although CFLs have come down dramatically in price, their electronic ballast and other features do make them more expensive to manufacture than incandescent bulbs. The payback period will vary with the cost of electricity in your area. However, based on a cost of 10¢ per kWh, a 15-watt CFL will cost about $12 to operate over its 8,000-hour projected lifespan. Burning a 60-watt incandescent bulb with equivalent light output for the same length of time will cost about $48; a cost difference of $36 (and you’ll need to buy four to eight bulbs since they have a much shorter lifespan). Based on those numbers, a CFL will pay for itself in about 500 hours (in about four months if the bulb is used four hours per day).
