LED flashlights have different colors of light, different wavelengths, different energy consumption, and different functions in practical applications.

At present, the light colors of LED flashlights mainly include white light, yellow light, red light, and blue light. Purple light does not belong to the category of LED and will not be discussed here.

1. White light

White light is currently the most widely used LED flashlight. White light is close to sunlight. Using white light for lighting in the dark is in line with the visual experience of our eyes.

Therefore, the eyes do not need to take time to adapt, and it should be the most comfortable color light for the eyes.

Moreover, white light is higher than other colors of light in terms of brightness and color temperature, giving people the strongest bright feeling.

2. Yellow light

Yellow light is often used in LED flashlights for jade identification. The yellow light here is different from the yellow light emitted by incandescent bulbs. Strictly speaking, the light emitted by incandescent bulbs is also a type of white light, but it appears warm yellow due to the low color temperature. .

The yellow light used in Zhaoyu flashlight is a monochromatic yellow light without mixing. It is the color light with the least refraction and scattering among all visible lights, so the yellow light has strong penetrating power.

It is often used to look at the texture of jade in jade identification. It is also more effective than white light when used in foggy weather. Some urban street lights also use yellow light.

3. Red light

Red light is widely used in outdoor hunting activities and works well. This is mainly because many animals only have rod cells or very few cone cells, resulting in insensitivity to color or even no color vision.

When hunting at night, you can use a red light flashlight to sweep unscrupulously without the prey noticing, greatly improving hunting efficiency.

For those who don’t hunt, red light is also a useful light color for outdoor activities.

Red light has good adaptability to the human eye. When the lighting color changes, the eyes need an adaptation process to adapt.

When we use a white light flashlight for outdoor activities, when our sight changes from bright to dark, it is dark adaptation, which takes a long time and will cause temporary “blindness”. However, red light takes a shorter time to adapt to dark. It effectively avoids the problem of temporary “blindness”, allowing us to treat our eyes better and maintain better night vision when we are active at night.

4. Blu-ray

In fact, most of the white light of LED flashlights is blue light. White LEDs actually produce white light by irradiating phosphors with blue LEDs.

Compared with white light, blue light is softer, does not have such strong reflection or even dazzling feeling. In addition, blue light has a special ability. Animal blood stains will emit faint fluorescence when illuminated by blue light.

Since blue light has high refraction and scattering rates when passing through the air, it usually does not propagate far, which means it has poor penetration. This can also explain why LED white light has weak penetration.

The above is the analysis of different light colors of LED flashlights. I hope it will be helpful to you.
