    Patent number: 7234973
    Abstract: A lighting system that includes a light bulb having a threaded bulb base and a luminare socket. The bulb (200) includes a two conductor base (201, 205) while the luminare socket (300) utilizes a circular ring (305) with an open aperture (307) for supplying current to the bulb. The circular ring (305) and aperture (307) in the luminare socket are sized to provide contact with the center contact (205) of the light bulb when the preferred wattage is selected. This prevents over wattage light bulbs from being used avoiding excess heat, arcing and the potential for fire.
