1. A lighting device comprising:
- a light source;
a power source for supplying power to the light source, wherein the power source has a chemistry composition and wherein the chemistry composition provides one of an alkaline electrochemical cell, a lithium electrochemical cell, and a nickel metal hydride cell;
a chemistry detection device, wherein the chemistry detection device determines the chemistry composition of the power source as one of the alkaline electrochemical cell, the lithium electrochemical cell, and the nickel metal hydride cell; and
control circuitry for controlling operation of the lighting device based upon the determined chemistry composition, wherein the control circuitry controls electrical power supplied to the light source to supply a first power when a first capacity chemistry composition is determined, and supplies a second power to the light source when a second capacity chemistry composition is determined.

Abstract
A lighting device is generally illustrated having a light body having forward facing light sources including a visible white light source, visible colored light source and an infrared light source. Additionally, a side facing light source is provided. The light body also includes switches for activating the visible light sources and a three-position switch for activating the IR light source and the side facing light source. The light source of the lighting device may further be controlled based on a detected chemistry composition of the power source.
