Led Lenser K4R

The Led Lenser keychain flashlight is a compact (body length 5 cm) and lightweight (weighing only 18 grams) solution for additional lighting. You can hang the model on a keychain for everyday wear and use it when there is a lack of light at home, at work and in the open. The device operates on an LED, which is supplemented with a reflector to increase the brightness of the light.

Also, the Led Lenser K4R flashlight provides focus adjustment, so the user can increase the size of the light spot (for better near illumination) or narrow the beam of light for increased “range”. The maximum luminous flux can reach 60 lumens, and the illumination range is 10 meters. There is also an additional mode - SOS. The built-in battery is used as a power source, providing up to 1.5 hours of battery life. The package includes a charging cable with the ability to connect to a USB port, so you can even power the model from a power bank or laptop. Other features include the readiness of the metal case for difficult operating conditions, because the manufacturer claims basic water protection and shock resistance.
