HL40R is the first headlamp with variable focal length. The headlamp is designed to maximise usability and ergonomics. The control knobs are positioned to make them easy to find, and switching modes and adjusting the beam is smooth without removing the flashlight from the head.This versatile model emits a maximum luminous flux of 600 lumens. The flashlight is perfect for illuminating a wide area in the immediate surroundings as well as illuminating objects at a greater distance thanks to the adjustable beam focal length. The beam can be adjusted from 13° to 52°. The maximum range of the focused beam is 147 metres. Combined with a mechanism that allows the flashlight to tilt 60° relative to the forehead, the flashlight is extremely flexible to adapt to the situation you are in. The flashlight is equipped with a built-in lithium polymer battery with a capacity of 2000 mAh, equivalent to 3 AA batteries, which provides up to 200 hours of operation. The battery is equipped with four low battery LEDs, which make it easy to detect when the energy level is low enough to need recharging.Reflectors on the headlamp strips increase visibility when hiking at night, especially when the flashlight is used to illuminate the road during evening jogging, making the user more visible to drivers. In addition, the wide strips on the inside of the headlamp have a silicone insert, which allows the flashlight to stay in place. The straps are soft and do not pinch, even when the flashlight is worn for long periods of time.An unquestionable advantage of this design is the impact-resistant aluminium housing and the IP66 protection class, which means that the flashlight can withstand heavy dust and rainy weather conditions.This flashlight will be appreciated by athletes, frequent evening runs, tourists and anyone who needs good lighting and a free hand for their tasks.TECHNICAL SPECIFICATIONSPage info Number of modes 7 Working time [h min] 200 Luminous flux [lm] 600 Range [m] 147Technologies used Diode type Cree™ XP-L HI (V2)Lens type Ultra Clear™ SafetyIP rating IP66 PowerCharge cycles up to 500 cyclesErternal built-in, Non-removable battery (2000 mAh / 3.7 V Li-Poly) × 1Power source micro USB portFurther detailsColor grayHousing material according to anodized duralumin MIL-SPEC and high quality plasticCover material absence Drop resistance [m] 1DimensionsWeight [g] 130Width [mm] 54Total height [mm] 42
