Editing Tactical light (section)

===Bulb===
Bulbs are chosen based on the desired light output and battery life.  Generally, high performance bulbs are used, such as [[xenon]] bulbs or high power [[LED]] lights.  LEDs provide maximum battery life due to their energy efficiency, and 2000s technology has greatly increased the light output of LEDs. At one time, xenon bulbs offered the brightest light levels, but recent high-power LEDs are brighter and more efficient than comparable xenon-filled incandescent lamps. Most importantly, LED bulbs are not subject to filament breakage due to the shot recoil of a firearm. Recent advances in high-lux, high-efficiency white LEDs have led to a wave of brighter and more energy-efficient tactical lights.
