Abstract:
A flashlight in accordance with an aspect of the invention includes an ID module for generating an ID signal indicative of a power mode of the flashlight. In an aspect, the flashlight mates with a removable battery pack that regulates at least one of an output voltage and output current in accordance with the ID signal. In an aspect, the flashlight includes a printed circuit board (PCB) on which the ID module is mounted. In an aspect, the flashlight includes a soft-start module and a bulb, wherein the soft start module increases power to the bulb at a controlled rate when the flashlight is turned on. In an aspect, the flashlight includes a lamp housing having a lens retained by a bezel. The lens includes an axially extending peripheral edge. In an aspect, the flashlight includes a main housing having a lamp housing. A mounting mechanism and mating features are adapted to selectively couple and decouple the main housing and the lamp housing. In an aspect, a flexible conduit connects the main housing and lamp housing. The flexible conduit can be formed in an arc having an apex that lies directly above a center of gravity of the flashlight when the main housing and the lamp housing are coupled, thereby allowing the flashlight to be balanced when the flexible conduit is used as a carrying handle.
