Abstract
An exterior light includes a base, a transparent enclosure, an upper dome, a bulb mounted within the enclosure on a vertically adjustable bulb holder, a primary reflector mounted in the dome and a secondary reflector mounted on the bulb holder for adjustable movement relative to the bulb. The secondary reflector and bulb move together as the bulb holder is vertically adjusted. The adjustments of the secondary reflector relative to the bulb and the combination of the bulb and secondary reflector relative to the remainder of the exterior light allow the light to produce different standardized illumination patterns. The dome may be translucent and the light may be constructed as a reproduction of an antique gaslight, including one or more gas mantles illuminated by the bulb.

An exterior light comprising:
- a base;
- a transparent enclosure mounted on the base;
- a bulb mounted within the enclosure on a vertically adjustable bulb holder;
- a shield mounted on the bulb holder for adjustable movement relative to the bulb, the shield and bulb moving together as the bulb holder is adjusted vertically;
