Bring up to 3 of your old light bulbs to the Cambridge Winter Farmer's Market and swap them for free LED replacements! This bulb swap is part of the City of Cambridge's 100% LED Campaign, which encourages residents to change all of their incandescent and CFL bulbs over to LEDs, which use six times less energy. Please note that only incandescent and CFL light bulbs can be swapped during this exchange.

Residents can also buy all of the other bulbs they need to go 100% LED at a popup store. Not sure which bulbs to get? Bring your current bulbs and staff can help you pick out the right replacements.
