Understanding the Different Beam Colors
With flashlights many manufacturers are offering additional beam colors in addition to neutral or cool white, the beam color is defined by the Cree led bulbs in the flashlights. If you have ever seen the different colored beams you might have been tempted to purchase one just because they are different. What you need to keep in mind with the different beam colors is that each color has a different meaning. Before you go out and purchase any additional beam colors let’s take a quick look at the options you have and what they are generally used for.
One of the greatest things about the white beam is just how bright it is. In fact, the white beam is the brightest of all the colored LED beams available. Photon has a beam that they claim is two times brighter than any other white bulb made from personal flashlights. White beams can be used for just about anything. They are designed to give you the ability to view everything you are looking at in full color.
Most flashlight will have a White LED Color
Aside from white, red beams are one of the most widely used colors in flashlights. Red beams are preferred by people who are trying to save their night vision, including hikers, sailors, and fisherman. With a red filter over the beam of your normal light you can easily read a map in the dark without needing your eyes to readjust to the light. Red beams are also ideal for map reading, safety, and signaling. Internationally the color red is recognized as a color to grab people’s attention, so it makes a great emergency signal.
The green beam/filter offers a very narrow beam band. The narrow beam is just one of the reasons as to why hunters prefer green lights to red lights in their scopes. Something else that makes green an ideal hunting light is that animals are not frightened off by green lights and it cannot be seen straight on. The green beams can only be seen from the side, which makes them the perfect choice for the times where you are trying to be stealthy.
Blue beams can be used as night and work almost as well as red beams because of the black lines that they cast against the white paper. Blue beams and filters can also be used by hunters at night because they are great for tracking blood trails along the foliage.
Something some of you newer flashlight enthusiast might not realize is that yellow is the traditional beam color and has one of the best projections, as it can project light for up to 30 feet. The downfall to yellow beams is that when used at night they greatly disturb your vision, so it takes a while for your eyes to adjust. Yellow beams are great for emergency kits where you need brightness more than anything else.
When thinking of purple beams we want you to think more along the lines of a black light. With purple beams make lighter colors look like they are glowing. The one thing that you need to watch out for with purple lights is that they do emit some UV light, so you do not want to look into it directly. The purple beam is a little different than the UV beam, as the UV beam is used in various applications by various organizations. UV beams are used by medical staff, law enforcement, etc. UV beams can be used to find body fluids, spot fake money, etc.
Now these are just some of the various beam colors offered for flashlights. Many manufacturers also offer dual beams, such as red/white, red/yellow, blue/red, etc. The benefit to the dual beam is that you get the benefits from both beams without having to purchase additional beams for your tactical flashlight.
