LED Flashlights: Getting the Most

From Color Bulbs

Colored LED lights have many uses, from professional to recreational. Green, red, blue, and ultraviolet rays have all found their way into the realm of LED flashlights. The services are varied, and each color has particular uses they are best suited for. All colored lights are great for night vision applications because they do not bleach out the chemicals that allow the human eye to see at night.

The red LED bulb has been added to flashlights to enhance night vision. It provides excellent contrast and is not visible to the human eye over long distances. It also works well with night vision scopes and goggles. Photographers use red-colored light when doing night-time photography because it provides contrast while preserving the natural shadows developed by darkness. It cuts through smoke better than white light and makes reading in low or no light possible except for red lines and marks on maps and charts. Police and military units like the red LED for night operations because it will not interfere with night vision technology and can't easily be picked up by others.

The green LED hunters and fishers prefer light because it is a very soft light that will not spook their prey. Green also does not attract insects like white or yellow light does. It is not easily picked up unless looking directly at it, so it is useful in covert operations. It is another color that is useful in smoke-filled environments.

The blue LED hand-held light is suitable for map or chart reading when night vision and avoiding detection are essential. Blue light is also helpful in locating blood and other bodily fluids at crime scenes or during search and rescue operations. Hunters also find the blue light useful in following blood trails of injured animals. Blue lights are often used in small keychain lights because they are soft light that works well to illuminate locks, keys, and small items. It does not have the same harsh glare as the bright, white LED. These lights are also suitable for cutting through the fog.

Ultraviolet LED lights have found many uses in the professional world. They are used to detect counterfeit money, art, and antiques. They also see trace blood proteins and chemicals in soils from crime scenes. Like blue light, this one will pick out blood and other bodily fluids that the naked eye might miss. Ultraviolet light acts like a black light in entertainment uses. It can bring out hidden messages and enhances neon and fluorescent colors. Ultraviolet rays can recharge luminescent objects like fishing lures, watch faces, compass needles, SAR signals, etc. It is important not to shine ultraviolet LED lights directly into the eyes, as it can cause injury.

Whether looking to preserve night vision for hunting applications or to cut through smoke in a burning building, colored LED lights are great for many applications. Their multitude of uses makes them a must-have for everyone. Flashlights are offered in single-color lighting or multiple bulbs for a choice of lighting options. This means that the right light is always available when it is needed. So, whether looking for a single light color for a specific application or multiple choices for whatever comes up, colored LED flashlights are great.
