CFLs and Mercury
Compact fluorescent lights do contain trace amounts (an average of 5 mg) of mercury vapor -- it's what makes the bulbs energy efficient -- an amount the size of the period at the end of this sentence. It's important to know that CFLs are safe to use and pose no danger when used properly. For more information, visit our CFL recycling page, or view our mercury fact sheet in the info library.

Always Dispose of Your CFL Properly
recycle CFLs

As energy-efficient lighting becomes more popular, it is important that we dispose of the products safely and responsibly. Proper recycling ensures the benefits of CFLs while properly managing the disadvantages.

Focus on Energy has partnered with the world's largest environmental service company to offer a solution. Focus representatives are providing interested retailers with recycling containers as part of a new, no-cost CFL recycling program for their customers.

Use our retailer search to find retailers participating in the program.
