Color temperature guide
Color temperature is the shade of light emitted by a flashlight. When you buy a flashlight, it’s important to find one with the right color temperature. The color temperature depends on individual preference and application.
You must be wondering why color temperature is a factor when buying flashlights. Well, consider a piece of black iron; heat it up and you will see that the color is changing as the temperature of the iron is rising.
First, after few seconds of heating, the glow of the iron turns red. Then the color changes to orange, then white and finally blue. Even when the iron melts because of heat, the glow of the iron will change to other colors depending on the temperature. At 27000Kelvin, the glow of iron is yellow; the same as that of an incandescent bulb. This is often called the ‘warm white’.
Color of flashlights is important as with certain colors you can view an object better whereas with others you won’t be able to have a good look at it. As a rule of thumb, warm colored LEDs, like yellow, are good for viewing objects at a close distance. Cool colored lights, like blue, are good for night vision.

Blue LEDs (470nm wavelength) are also good for night vision. You can read a map well at night using blue flashlight. Pilots often use blue LEDs to read maps during night. Blue LEDs are also used by crime scene investigators or police to find trace of blood or other body fluids which will not be visible with other colored lights. Blue is also the only light that can pass through fog and so has wide applications in vehicle headlights.
Ultraviolet LEDs, having wavelength of 365-400nm, are used to check the authenticity of driving license, money or other documents using watermarks. Plumber, mechanics and other workers use it to detect HVAC leaks. Crime investigators use ultraviolet LEDs to see blood and other stains more clearly.

You can easily find scorpions around your house with ultraviolet LED, as they turn green when the light falls on them. In mineralogy, ultraviolet lights are widely used to identify minerals.
Infrared LED (having wavelength 750-1000 nm) illuminates a night scene and so is very useful when going on hunting at night. Infrared light cannot be viewed with a human eye.
