Because LED light technology is developing so rapidly, consumers are hard-pressed to keep up. This leads to many common misconceptions about LED flashlights. For example, earlier LED light bulbs gained a reputation for producing a cold, bluish-white light. While this may have been true a decade or so ago, today’s LED flashlight models are capable of producing a wide variety of hues for various applications.
As anglers and sportsmen discover the benefits of colored LED light for outdoor use, more and more of them are taking advantage of colored LED flashlights. The following is a look at some of the most common LED light colors and how they’re used.
RED: One of the most common complaints hunters have about using flashlights to move about in the dark is that they destroy one’s night vision, which can take hours to fully recover. A red LED light is useful in such cases, as it can provide enough illumination for moving around while still preserving night vision. Red lights are also commonly used for emergency signals, as they’re effective at attracting attention, especially in smoky environments.
BLUE: Many hunters also find blue LED flashlights useful. Blue light is particularly penetrating, which makes it effective at cutting through fog. It’s also better than white light at illuminating blood trails, which makes blue LED light handy for tracking a wounded animal.
GREEN: Green light is especially useful if you need to be stealthy. Fish and game are notoriously sensitive to bright lights, especially in the white and yellow ranges. A green beam of light is hard to see compared to other colors (unless you’re looking at it dead on) and is perfect if you’re trying to avoid spooking the fish.
ULTRAVIOLET: Ultraviolet LED lights are powerful beams; they can be used to recharge luminescent objects, such as watches, fishing lures or compass needles, as well as to reveal the mustard stains on your friends’ clothes. However, they should never be shone directly into the eye.
