Abstract
A Shabbat bulb and a related method allows control of illumination without electrical intervention by a person observing strictures of Shabbat orthodox Jewish law. The bulb includes a blackout mechanism with shutter disc having at least one disc aperture for transmission of light and gear teeth; and an arm projecting radially outward from the shutter disc fitted with drive gear teeth. Manual rotation of the arm engages drive gear teeth with shutter disc gear teeth moving the disc apertures from an open to a closed position respectively allowing full or totally no illumination to exit the bulb.
