A lamp includes a bulb that is held within an openable housing. When the lamp is turned on, the bulb gradually lights and the housing gradually opens to expose the bulb. When the lamp is turned off, the housing closes around and thereby conceals the bulb. Methods for opening the housing include a sliding piston system, a cam and lifter system and a gear and rack system. When the lamp is turned on or off, music may also be played or other such sounds generated.
