Swap out your old bulbs at our Illumination Stations!

Illumination Stations & Lightbulb Exchanges are information tables that shine a light on ways to lower your utility bills, learn about energy assistance programs, and connect with trusted county and utility resources. Visit your local Montgomery County Public Library to talk with staff and partners about energy efficiency programs, Pepco services, and other helpful county offerings.

Residents are also encouraged to bring old incandescent or compact fluorescent light bulbs (CFLs) to exchange for new energy-efficient LED bulbs. Standard 60-watt equivalent LEDs with a warm 2700K color temperature are available, with a limit of three LED bulbs per person. Residents interested in additional upgrades can learn about scheduling a Quick Home Energy Checkup through their utility company.

This program is presented in partnership with the Montgomery County Department of Environmental Protection (DEP), Montgomery County Public Libraries, Montgomery County Department of Health & Human Services, and Pepco.

Please note that dates and locations may change due to weather or other unforeseen circumstances. For the most up-to-date information, visit the My Green Montgomery Community Calendar and look for Illumination Station & Lightbulb Exchange events.
