Torches with red light
Red light
— one of the more popular complementary colours in modern flashlights; can be used both in combination with blue and green (in the so-called RGB models), and as the only auxiliary shade. One of the features of red light is that it practically does not affect night vision, does not penetrate through the eyelids, and even after complete darkness does not blind the eyes. This makes such lighting the best option, for example, for clarifying map data during a night trip, when you need to quickly restore vision after turning off the light, or for emergency lighting in a sleeping room, where you need to see the environment and at the same time it is undesirable to disturb sleeping people with the light. . Another way to use red light is signaling: this light travels farther than blue or green, and stands out prominently against most landscapes and man-made objects. The change of shade can be carried out both due to the light filter on the main light source, and due to a separate LED.Show
