Isn't this a problem for landfills? Are we going to start hearing about dangerous mercury levels in the ground and water in a few years?ĬFLs have very low levels of mercury in them, now as low as 2 mg per bulb. Additionally, CFLs may not turn on or reach their full brightness in really cold temperatures.Įveryone I've talked to says they just throw dead CFLs in the trash. Switching your CFL on and off frequently may shorten its life. Those bulbs are not only efficient but also meet the Environmental Protection Agency's rigorous performance requirements and must pass various tests including longevity. I have some bulbs that last years but others that die within a year.Īs not all CFLs are created equal, only buy those that have the Energy Star logo on them. Why do some CFLs die so quickly? The whole seven-year life thing seems random.
