So why would I want a flashlight that produces any light other than white? The primary purpose of a flashlight is to provide illumination during periods of low light. Most folks are happily contented with the output white light from the majority of flashlights now available. However, there are occasions when the bright white light from a flashlight can be a little offsetting especially when outdoors. Having a flashlight which can produce red and green light gives the user the option of not only illuminating an area but having the capability to make the most of the conditions prevailing at the time. Red light is easier on the eyes than white light and its use will not be easily detected thus giving the user an advantage in a low light environment. Green light would be the obvious choice for the user who spends long periods in the fields and hills where this hue would be an absolute necessity among the flora and fauna.
