Throughout the year, we will be partnering with community organizations to provide residents with LED lightbulbs. DEP staff host light bulb swaps at libraries and at Summer community events. During the light bulb swaps, participants are asked to bring in their old incandescent or CFL lightbulb. In exchange, we provide up to 3 free LEDs at no cost. We also bring an informational table and giveaways for participants. Pepco has graciously supplied the LED bulbs. Come out and meet our Energy Ambassadors!
