          • CUSTOMER CARE

            A:

            This bulb is a 2-pin compact fluorescent and cannot be used with dimmers. Only the 4-pin compact fluorescents can be dimmed using the proper dimming ballast.

          • CUSTOMER CARE

            A:

            If the bulb is similar to the one on our site then it should just pull out of the socket. It is best to hold the ceramic part when removing the bulb as opposed to holding the glass. Wearing gloves (in case the glass breaks) and turning the power off to the fixture is also recommended.
