Are compact fluorescent lightbulbs (CFLs) dangerous to use?
The amount of mercury in a CFL bulb is very small. Much more mercury is emitted by manufacturing electricity to light a conventional bulb and it is floating freely in our air. If you break a CFL, sweep it into a shoebox and take it to your local Community Recycling Center. You can also choose to use LED bulbs, which are as energy efficient or more than CFLs and do not contain any mercury.
