The Walther KFA1 flashlight is an excellent choice for a keychain lamp, offering both convenience and ease of use. It features three distinct light levels—low, medium, and high (5, 25, and 110 lumens, respectively)—with the lamp defaulting to the medium setting when turned on. You can easily adjust the intensity of each light level using the rotary head. The flashlight is powered by AAA batteries and boasts a durable aluminum housing that is hard anodized and IPX8 waterproof. Additionally, it comes with a key ring for added practicality.
