Ultraviolet radiation: Researchers find dark side of CFLs

The lamps emit surprisingly high levels of ultraviolet radiation.

ISLAMABAD: Energy-efficient compact fluorescent light bulbs (CFLs) commonly known as energy savers are a popular choice for homeowners and businesses looking for ways to reduce their electricity bills. But researchers at Stony Brook University in New York have discovered CFLs have a darker side, too: The lamps emit surprisingly high levels of ultraviolet (UV) radiation, which can damage skin cells and, at high exposure levels, cause cancer, Live Science reported. According to lab test healthy human skin cells experienced significant damage when exposed to light from the CFLs. “The results were that you could actually initiate cell death,” Marcia Simon, professor of dermatology at Stony Brook University. Skin cells exposed to the old style bulbs suffered no significant damage. CFL manufacturers refute the Stony Brook researchers’ finding, issuing a statement claiming that “the levels of UV radiation emitted are acceptably low,” and these light bulbs are safe for normal use.
