FAQ

CFLs, including GU24 bulbs, contain a miniscule amount of mercury - about 5 milligrams. Mercury helps make compact fluorescent bulbs energy efficient.

However, compare the power plant emissions over the lifetime of an incandecsent bulb to a CFL. Incandescent bulbs generate 13 mg of mercury into the environment. CFLs generate a paltry 3-1/2 mg.

Any compact fluorescent bulb should still be recycled or disposed according to local guidelines. Contact your local municipal solid waste agency or visit Lamprecycle.org.
