This single-mode red light flashlight is designed for nighttime activities. The human eye is highly sensitive to red light, and many animals are less startled by red illumination, making it useful for observing wildlife in low-light conditions. This red LED flashlight allows users to locate animals such as hogs, coyotes, and es without disturbing their natural behavior. Ideal for outdoor enthusiasts and wildlife observers, this flashlight supports night observation without startling animals. Using white light can cause animals to flee, but red light helps maintain a discreet presence, enabling closer observation of turtles, snakes, and other reptiles. The flashlight features a simple on/off switch and operates in a single red LED mode. Slide the head back and forth to adjust the beam focus, providing a zoomable light beam with a range of over 150 yards. The red light can also be used for signaling, emergency assistance, or warnings. Powered by one 1.5V AA battery or compatible rechargeable AA-sized battery (maximum voltage 4V), the flashlight's brightness increases with higher voltage input. Increased brightness may generate more heat on the flashlight body. Users should select the battery type according to their desired brightness level.
