Which LED color is right for you?
 
Customers often ask us about the purpose of having different-colored LED flashlights. Each LED color has different characteristics that allow for varied applications. Also, each person has a unique visual acuity and, as a result, a personal color preference. Colored LEDs are different from a lens filter because the LED produces pure spectrum color - not dyed or filtered white light - the LED will only produce the intended wavelength and therefore offers more reliable results than a lens filter.
  
Beam color characteristics:
 
White - White light is a great choice for general use. Everything is viewed in full color and therefore most similar to "daytime light". 
 
Red - Red light is favored by pilots, sailors, fishermen, and astronomers for its excellent ability to preserve night vision. Red light is also used for safety and signaling; red is an internationally recognized attention color. ~630 nm.
 
Orange - Orange LED light combines some of the aspects of both red and yellow light. The light is very bright, doesn't disturb night vision as much as yellow, and illuminates better than red. ~605 nm.

Green - Green light is nearly as bright as the blue, turquoise, and white lights but it has a longer battery life. A green LED uses less energy than other colors and will last longer with one set of batteries. Green light is often used in place of red for reading maps that have red lines on them (the red lines would be invisible when using a red light source).  ~525 nm.

Blue - The blue beam is tremendously bright. Blue can be used to enhance contrast and it can also be used to identify some fluids (for military/industrial applications). ~470 nm.
 
Purple - Purple bulbs create a black-light effect, making lighter colors appear bright. Purple bulbs do produce some UV light, which can be harmful if viewed directly. ~405 nm.
 
Specialty Lights:
 
Ultraviolet (UV) - UV light has a variety of specialty applications. It can be used to: authenticate money, expose imitation art, identify minerals, follow blood, bacteria and protein trails, authenticate collector glass and stamps, and accelerate curing glue. Medical staff, law enforcement personnel, collectors, cashiers and model builders are the main users of UV lights. ~370 nm.
 
Infrared (IR) - Infrared light is invisible to the naked eye. When used in conjunction with night vision equipment, it can illuminate an area in a way that can only be seen through the night-vision equipment. This type of light is ONLY useful when used with night vision equipment or other equipment sensitive to infrared light. ~880 nm.
