ABSTRACT:
To permit sufficient illumination for a plastic-sealed general purpose lamp, a bulb is encased in plastic and sealed, with the plastic shell of the lamp having wide parallel faces, one of which may include a reflector to focus light. The lamps may be battery or AC controlled and have a handle for holding them and a magnet mounted in them for mounting to a surface magnetically. To control the intensity and location of the light flux emitted from the lamp, a plastic lens and reflector may be incorporated in the lamp with the inner light bulb between the two. For greater power dissipation, dead space of approximately two cubic inches is placed around the lamp in some embodiments.
