Which color temperature do you prefer?
As we all know, the light of the flashlight is the most direct factor to judge the performance of the flashlight. Usually, we only pay attention to whether the lumen value of the flashlight is high or low - the higher the lumen value, the brighter the light emitted by the flashlight. Therefore, when designing flashlights, most companies will set different gears to meet the different needs of customers for light, but relatively little attention is paid to color temperature. The color temperature of the flashlight is used to describe the color of light. For example, the sun in the sky emits different colors of light at different times, such as red light in the morning, white light at noon, and red light in the evening. Different colors correspond to different color temperatures.
Color temperature can be roughly divided into two types: cold and warm. The lower the color temperature, the warmer the color of the light, and the higher the color temperature, the cooler the light’s color. Whether the color temperature is comfortable mainly depends on the degree of its irritation to the eyes. Generally speaking, the color temperature of warm colors will make people more comfortable, while the cool colors are relatively dazzling. Defining color in terms of temperature is a novelty and can be difficult to understand. But we can think about it from another angle. For example, when you burn iron products with fire, you will find that during the heating process, the iron products will gradually change from dark-red to orange-red, white and blue. This is because the color of iron products is determined by the temperature at which it is heated. In this way, it is an easy thing to understand the concept of defining color by temperature.
For hunters who love hunting, red light is the most suitable light color because many animals are insensitive to color or even have no color vision. When hunting at night, they can use the red-light flashlight recklessly to sweep away the prey. It can greatly improve the efficiency of hunting. In addition, when the color of the illumination light changes, the human eye needs an adaptive adjustment process before it can adapt. When we use a white light flashlight to illuminate outdoors, our vision needs to change from a bright place to a dark place, which belongs to dark adaptation and takes a long time. Red light can take less time during dark adaptation so that we can better protect our eyes and maintain better night vision when we are active at night.
Yellow light is the least refracted and scattered light color of all visible light due to its specific wavelength. That is to say, yellow light is the most penetrating, and yellow light travels farther than other visible light under the same conditions. For outdoor sports enthusiasts, the outdoor environment at night is usually accompanied by water vapor and mist. In this case, a yellow flashlight is perfect.
White light is the most widespread light color in LED flashlights. White light is close to sunlight and it is also the most comfortable light color for the eyes. Using white light in the dark is in line with the visual experience of our eyes because the eyes don’t need to take time to adapt. White light is higher than other light colors in terms of brightness and color temperature, giving people the strongest bright feeling and suitable for long-distance lighting, so white light is widely used in outdoor activities such as night hiking and camp lighting. The blue light usually travels not far, that is, the penetration is poor.
Different color temperatures have different effects on the atmosphere. When the color temperature is less than 3300K, the light is mainly red, giving people a warm and relaxing feeling. When the color temperature is 3300-6000K, the content of red, green and blue light accounts for a certain proportion, making people feel natural, comfortable and stable. When the color temperature is above 6000K, the blue light accounts for a large proportion, which makes people feel serious, deserted and low in this environment.
The color temperature of warm light flashlights we use in daily life is generally 3000K-3500K, the color temperature of neutral light flashlights is generally around 4000K-4500K, and the color temperature of white flashlights is generally around 5500K-7000K. Which one do you prefer?
