JF1102 5 Colors Tactical Flashlight 10W XML-L2 LED Pressure Switch Rail Bracket

• L2 LED beads, with a high brightness of up to 1500 lumens and a lifespan of 100000 hours;
• Lens: Good light transmission performance, not easily damaged, sturdy aluminum attack head protection lens from wear and tear;
• Fixed focus: Good focusing effect and long illumination distance;
• Central switch: Made of high-quality natural rubber material, with anti slip surface treatment. Touch the switch to switch lighting modes, and long press the switch to turn off the lights;
• Battery contact: The spring shaped battery contact design has good conductivity and effectively prevents poor contact.

• White light: Lighting with white light in the dark is in line with our visual experience, so the eyes do not need to spend time adapting, it is a color light that makes the eyes comfortable. Moreover, white light has higher brightness and color temperature than other colored lights, giving people a strong sense of brightness.
• Yellow light: To deal with water vapor and mist, yellow light is the color light with the least refraction and scattering among all visible light. That is to say, yellow light has strong penetrability, and under the same conditions, yellow light propagates further than other visible light.
• Red light: Improves efficiency. The human retina contains two types of photosensitive tissues, pyramidal cells that distinguish colors and rod cells that distinguish contours. Many cells only exist as rod cells or have very few cone cells, resulting in insensitivity to color or even no color perception. When searching at night, you can freely use a red flashlight to sweep and make it unaware, greatly improving efficiency. Red light is still a very useful color for outdoor activities. The eyes have adaptability - when the lighting color changes, the eyes need a process of adaptation and adjustment to adapt. Adaptation can be divided into two types: dark adaptation and light adaptation. Dark adaptation is an adaptation process from light to dark, which takes a long time; Bright adaptation is the process of transitioning from darkness to brightness, which requires a short amount of time. When we use a white light flashlight for outdoor activities, the shift of our gaze from bright to dark is considered dark adaptation, which takes a long time and may result in temporary "blindness". In contrast, red light requires a shorter time for dark adaptation, which effectively avoids the problem of temporary "blindness" and allows us to better treat our eyes and maintain good night vision during nighttime activities.
• Blue light: Tracking traces, most white light LEDs actually produce white light by illuminating fluorescent powder with blue light LEDs, so LED white light contains more blue light components. Due to its high refractive and scattering indices when passing through air, blue light usually travels a short distance, resulting in poor penetration. But the traces of the object will emit faint fluorescence under the illumination of blue light. By utilizing the characteristic of blue light, European and American enthusiasts also commonly use blue light flashlights to track traces and ultimately find the target.
• Green light: Green light is a color that many people are not sensitive to, but the human eye is very sensitive. At the same brightness, compared with blue light, red light, and white light, the human eye will feel that green light is the brightest. In outdoor scenes with lush foliage, other colors are mostly absorbed by green leaves, while green light is more likely to penetrate the jungle. In specific scenarios, green light is easier to search for objects with darker body colors, especially when obscured by dense vegetation. This advantage is most prominent, and for some experienced people, green light is less likely to be startled.
