Flashlights by light colour: the right light colour for every situation
There are different colours of light in flashlights. But why choose a torch with red or blue light, for example? The different light colours all have their own advantages, allowing you to see better in certain conditions. For example, red light is widely used by hunters, green light by fishermen and blue light for trace detection. Read on to learn more about the applications of different light colours.
Light colours and applications
Flashlight red light - hunters, outdoor sportsmen, guards
Torches with red light are specially designed to provide a soft, glare-free light. Therefore, this light colour is widely used by outdoor athletes, guards, hunters and military personnel. Red light does not disturb your night vision, is often not or poorly seen by animals and is less conspicuous than white light from a distance.
Flashlight green light - hunters, military, fishermen
Green light interferes with the eye's natural night vision capacity less than white or red light. It is therefore often used by soldiers and hunters. Moreover, green light has the advantage of being barely noticed by most animals, making it ideal for observation or reconnaissance. Moreover, green light is also used in medical and engineering applications for precision work, as it increases contrast and reduces eye fatigue with prolonged use.
Flashlight blue light - trace investigation, Search & Rescue teams
Torches with blue light offer bright, yet mild light that is highly visible even at long distances. Blue light is therefore often used by emergency services such as police and firefighters, as it helps to illuminate a situation without blinding. It is also used in night-time activities and hunting, as it does not scare animals as much as white light, but blood can be seen well under a blue light.
Flashlight UV light - making the invisible visible
Torches with UV light emit a specific wavelength range. This is ideal for detecting certain materials and traces that are invisible to the naked eye. For example, UV light is often used by forensic investigators and cleaning professionals as it helps detect blood, stains and other biological substances. UV light can also help identify forgeries, think official documents and works of art. In addition, watch lovers also benefit from UV light: This is because UV light activates the 'lume' on the dial, making this luminescent material glow in the dark. Cool!
