Please dispose of CFLs responsibly.

CFLs contain a small amount of mercury and need to be disposed of properly, preferably recycled.  The U.S. Environmental Protection Agency (EPA) has updated its guidance on how to properly clean up a broken CFL.  Included with the guidance is a new consumer brochure with CFL recycling and cleanup tips.  Find local retailers and recyclers who accept used CFLs at
