Let's kill this rumor before it even gets off the ground: Compact fluorescent lights, or CFLs, are no more a fire hazard than regular incandescent bulbs. One writer to the Green Guide expressed concern because his CFL burned out, leaving a charred base, some smoke and emitting a bad smell. No need to worry as long as the bulb has the Underwriters Laboratory (UL) seal, the Green Guide assures us. Good thing too, as there's no doubt CFLs are good for the environment and your electrical bill. They are 10 times as energy-efficient as incandescent bulbs. So, don't let this rumor and others deter you from installing CFLs in your home.
