Abstract
A portable light may comprise: a light housing for enclosing a source of electrical power and supporting an electrical light source, a face cap rotatably mounted to the light housing. The face cap may have one or more lenses positionable in front of the electrical light source. A light source control circuit interior the light housing has at least one switch actuator for selectively energizing the light source, and an actuator member of the face cap. Rotating the face cap moves the actuator member into a position to actuate the switch actuator, whereby rotating the face cap produces the selective energization of the light source. The portable light may require a tool to open the housing, e.g., to replace the source of electrical power and/or may be pivotably mounted to a light base.
