These days it’s easy to be in the dark when selecting a light. Federal law is phasing out some incandescent bulbs in favor of more energy-efficient ones. New technologies, including CFLs and LEDs, complicate making a selection. How do you pick one over the other?

Regardless of the bulb you pick there are several things to consider: the light fixture, the color of light, whether it needs to turns on fast, how often you use it and for how long, and cost.

CFLs take longer to reach the full light output than traditional incandescent bulbs and LEDs. A chemical reaction produces visible light using a fluorescent phosphor coating on the inside of the tube. This reaction typically takes 30 seconds to three minutes to complete and deliver the full brightness.

“We recommend using CFLs anyplace where lights stay on a long time,” said DuWayne Dunham, Clark Public Utilities energy counselor. “Floor lamps, reading lamps and security lights seem ideal for CFL bulbs.”

LEDs turn on instantly, because they use semiconductors, called light-emitting diodes. “LEDs are better for places where an instant on is important, like in bathrooms and closets or on dimmers,” Durham said.

They also work well in track lighting. Placing LEDs in the fixtures of high ceilings can reduce the need to rent a scisso…………… continues on The Columbian
