1. A flashlight comprising:
- a lamp;
a power storage element;
a first input device;
a second input device;
an electronic controller;
the controller having a first switch input operably connected to the first input device;
the controller having a second switch input connected to the second input device;
the controller being operable in response to operation of the first input device to deliver power to the lamp;
the controller being operable in response to a signal received from the second input device to select an intermediate level within a range of the lamp'"'"'s capability, such that the second input device determines a brightness of the lamp; and

Abstract
A flashlight has a lamp, a power source, two switches, and a controller connected to the switches. The first switch controls delivery of power to the lamp, and the second switch selects a dimmed brightness level. The first switch may invoke the dimmed level, or a maximum brightness level. The second switch may be a ring rotatable about the axis the flashlight, and either rotatable through a wide range of positions, with sensor circuitry to detect the absolute position, or having a limited range of rotation, with dimmed level selection provided by a duration of momentary rotation in either direction. The second switch may be positioned outside a leak resistant housing, and may include a magnet detectable by magnetic field sensors within the chamber.
