Compact Fluorescent Light Bulbs
Compact Fluorescent Light (CFL) Bulbs are becoming more popular for good reason. According to Energy Star, if every American home replaced one light bulb with a CFL bulb, we would save enough energy to light 3 million homes for a year, save about $600 million in annual energy costs, and prevent 9 billion pounds of greenhouse gas emissions every year, equivalent to those from about 800,000 cars.
A CFL bulb can screw into a standard light socket and is made of glass, a ceramic and metal base, phosphor powder, and a very small amount of mercury (less than 1/100th of the amount in a mercury thermometer.) CFLs use much less energy than regular bulbs.
Due to the mercury, there are several ways to properly dispose of CFL bulbs. They include:
- Store your burned out CFLs in a zip-lock bag until they can be properly disposed of. That way, if the bulb breaks, the mercury vapors are contained.
- Bring your CFL bulbs to one of our Household Hazardous Waste events.
- Some home improvement retail locations, such as Home Depot and Lowes accept CLF bulbs. Please confirm with your local store prior to taking them in.
