695nm LED FLASHLIGHT , peak wavelength of 695 nanometers.

This LED flashlight features an LED with a peak wavelength of 695 nm. The tail cap includes a push button for turning it on. The flashlight has only ON/OFF modes. The body is made of aluminum, with a length of 98 millimeters and a head diameter of 25.5 millimeters. It uses one AA battery and provides approximately 2 hours of continuous use.
Brightness details are as follows:
The intensity is 5.1 milliwatts per square centimeter, measured from a distance of 5 cm.
It has a brightness of 0.42 lumens.
The peak wavelength is 695 nm.
Although the peak wavelength of this LED is 695 nm, the wavelength range extends from about 630 nm to 730 nm. Specifically, it gradually increases from around 630 nm to 690 nm, then decreases through 700 nm and 720 nm.
Effects
Visibility Enhancement: Red light is highly visible, especially in low-light conditions or at night, and is less straining on the eyes for prolonged use.
Biological Effects: Red light is known to promote cellular repair and regeneration, and it is used in medical fields for therapeutic purposes. Specifically, light at 695 nm can be used for skin and muscle treatment.
Impact on Night Vision: Red light maintains visibility in dark environments with minimal impact on night vision, making it suitable for activities and tasks performed at night.
Reduced Light Pollution: Light at 695 nm is less likely to cause light pollution compared to blue light, which is beneficial for preserving the natural environment and minimizing disturbance to nocturnal wildlife.
