A lamp assembly includes a sealed lamp envelope enclosing a filament, a lamp base affixed to the lamp envelope and including a connector, and an automatic light control circuit located in the lamp base and electrically connected between the connector and the filament. The light control circuit includes a photosensor for controlling the power delivered to the filament in response to a sensed ambient light level. Preferably, the lamp base includes a cup-shaped portion affixed to the connector, and the light control circuit is mounted in the cup-shaped portion on a circuit board. The photosensor is mounted in a hole in a sidewall of the cup-shaped portion. The lamp assembly can be installed and operated in a conventional lamp socket.

A '3-lite' incandescent lamp structure is disclosed which is capable of being mounted in either a 'base down' orientation or a 'base up' orientation without damage to the internal glass button support assembly. A shield is provided adjacent to the glass button support assembly to minimize damage to the support assembly from the gaseous deposition products generated by the lamp filaments.
