Fenix HM75R SE Headlamp — a compact professional model from Fenix
Brand: Fenix. Model: HM75R SE. This headlamp is a simplified and more affordable version of the Fenix HM75R: it retains a wide range of modes and high technical specifications, but comes with a single ARB-L18-3400 battery, which reduces the purchase cost (if necessary, an additional battery can be purchased separately).
The flashlight is equipped with four LEDs: 1 x Luminus SST40 (6500K), 2 x Luminus SST20 (4000K), and 1 x OSRAM GR QSSPA1.23 red. The LEDs are protected by ultra-durable lenses made of Japanese PC-1250Z plastic, which increases the optics' longevity and beam stability.
Smart solutions and safety
The device is equipped with an automatic brightness reduction system when approaching an object closer than 60 mm, which helps prevent ignition of flammable liquids and reduces the negative impact of bright light on vision. Overheat protection is also provided: if the case temperature rises to 60°C, the electronics reduce power for cooling.
Operating modes and control
The interface consists of 3 mode groups, each with 4 brightness options. Group switching is done using a metal rotary switch, and brightness level changes are made with the central mechanical button.

Power source and charging
The kit includes an ARB-L18-3400 li-ion battery with no "memory effect," which stably powers the device during temperature fluctuations. The battery is charged via a built-in USB Type-C port, located on the side of the case and protected by a cap. A colored charge status indicator allows monitoring the energy level. The kit can be supplemented with a second 21700-size battery, which is placed in an external block. The specifications indicate the power source as 1 x 18650 (pay attention to compatibility and recommended battery models).
Housing, dimensions, and protection
The housing is made of magnesium alloy, ensuring high corrosion resistance and low weight — the total mass with the battery is 134 g. The design withstands drops from a height of up to 2 m, and the IP68 protection rating allows the device to be submerged in water up to 2 m deep for up to 4 hours. Housing dimensions: 91.1 x 41 x 53.5 mm. The kit includes a head strap with reflective elements, suitable for wearing on the head or a protective helmet, and features length adjusters for the elastic straps.
