CFLs as safe as standard light bulbs, laboratory says

April 1, 2010

Compact fluorescent lights are at least as safe as standard incandescent lights, suggests recent research from Underwriter's Laboratories in Northbrook, IL.

UL performed safety tests with CFL bulbs in standard household lamps and open fixtures, according to a press release from the laboratory. The tests found no additional safety issues or hazards when compared to an incandescent bulb. Research indicated that recent advances in CFL technology eliminated prior safety concerns of popping sounds or smoke when the bulbs burned out, and temperature tests found CFL bulbs emitted less heat than a standard 40-watt incandescent bulb, the release said.

"UL's research will help give peace of mind that CFLs are safer and will provide valuable information for manufacturers as CFL technology evolves," said Alex Boesenberg of the National Electrical Manufacturers Association in Rosslyn, VA, in the release.

UL reports CFLs currently are installed in approximately 11 percent of available sockets in homes.
