Fenix HM75R Superraptor 3S 1800 lm is a rechargeable headlamp and powerful helmet light for demanding cycling, including mountain biking, gravel riding and year-round commuting. The included Fenix ALG-03 V2.0 helmet mount enables secure and easy installation on most cycling helmets using either the supplied mounting adhesive pad or separately available cable ties. A maximum output of 1800 lumens and a beam distance of 230 metres help you detect trail contours and obstacles in time.
The separate spotlight and floodlight can be selected individually or combined into a balanced beam pattern. A long-reaching spotlight and wide close-range illumination provide visibility both nearby and at a distance, making it easier to distinguish route details. In addition to four white-light output levels, the lamp features three red-light modes with outputs of 2, 30 and 120 lumens.
The ultra-lightweight and durable magnesium body makes this 173-gram light well balanced to use and reduces strain on the neck during extended use. The mechanical rotary switch and electronic push button can also be operated while wearing gloves, and the memory function stores the last-used brightness level for the next use. The reflective headband fits head circumferences of 50.5?64.5 cm, and an overhead strap is also included.
The light is powered by the included replaceable Fenix ARB-L18-3500 lithium-ion battery with a capacity of 3500 mAh. Waterproof USB-C charging and a charging time of approximately three hours make it easy to recharge the battery between uses. The light is also compatible with two separately sold CR123A batteries. The lithium-ion battery operates in temperatures down to -20 °C, while use with CR123A batteries is possible down to -40 °C.
Two energy modes allow you to manage output and runtime. Eco mode extends runtime, while performance mode provides higher brightness. Maximum runtime is 211 hours on the floodlight's 5-lumen low mode. The separately sold POWER EXTENDER auxiliary power supply can extend runtime to up to 447 hours and also functions as a USB-C power bank for a phone or GPS device, for example.
The IP68-rated construction is completely dustproof and waterproof to a depth of 1.5 metres. The light withstands drops from a height of two metres, and its impact resistance is rated at IK10 level. It has been designed in Finland based on user feedback, tested for year-round use and awarded the Design from Finland mark. Fenix light performance values are tested in the company's own laboratory in accordance with the ANSI/PLATO FL1 standard.
The versatile beam pattern, replaceable battery and durable magnesium construction make this light a reliable choice for users who need both a long-reaching spotlight and a wide close-range beam in one light. The helmet mount, headbands, red-light modes and alternative power sources further expand its range of applications.
Recommended use: especially suitable for cycling, mountain biking, gravel riding, commuting and other extended activities that require adjustable light output for both close-range and long-distance visibility.
