Fenix HP35R Headlamp
The search and rescue lamp of the HP series with a detachable battery pack

Searching an area at night takes two things at once: a beam that reaches the edge of the forest, and a wide field right in front of your feet – most headlamps manage only one of them. The HP35R combines a CREE XHP70 for the spot with two Luminus SST20 for the flood and delivers 4'000 lumens over 450 metres in combined mode.

Buy the Fenix HP35R headlamp – 4'000 lumens for search, rescue and expeditions

The Fenix HP35R is a headlamp with a detachable battery pack on the head strap, built for search, rescue, expeditions and caving. Three LEDs sit at the front: a CREE XHP70 in neutral white for the directed spot and two Luminus SST20 in warm white for the flood – together 4'000 lumens, 450 metres of beam distance and 50'853 candela in turbo. The light has 3'000 kelvin and a colour rendering of CRI 94.5, so colours stay distinguishable at night too. Control runs through a rotary dial and an electronic switch: three operating modes with four brightness levels each, digitally regulated for constant output, with a memory function for the level you used last. The energy comes from two integrated 5'000 mAh batteries in a quickly detachable pack that charges in around two hours through a waterproof USB-C port and doubles as a power bank. You will find more models from this manufacturer on the Fenix brand page.

440 or 450 metres? What spot, flood and the combination really deliver

The ANSI FL1 figures differ by operating mode, and the difference is noticeable in the field. The pure spot beam manages 3'000 lumens, 440 metres and 48'518 candela in turbo with a runtime of 5 hours 43 minutes; on high it is 800 lumens and 230 metres over 11 hours 40 minutes. The flood covers the near field instead: 1'200 lumens and 122 metres in turbo, 400 lumens and 68 metres on high with 30 hours 48 minutes, and right at the bottom 5 lumens over 500 hours for work inside the tent. Only both systems together produce the peak figures: 4'000 lumens, 450 metres and 50'853 candela – at 4 hours 17 minutes. The frequently quoted 450 metres therefore apply exclusively to combined mode, not to the spot alone. If you only need distance and want to save runtime, the spot on high is the most efficient choice.

Battery pack, charging and power bank – the energy side

The battery pack sits at the back of the head and detaches quickly. That has two practical consequences: you can tuck it under your jacket in the cold, and you can carry a second, charged pack instead of waiting for a socket – matching spare battery packs are available separately. Charging runs through a waterproof USB-C port and takes around two hours thanks to the PD3.0/2.0 fast charging protocol. In the other direction the pack works as a power bank and brings a phone or GPS back to life. A charge level indicator shows the remaining capacity, and the lamp actively warns at low voltage. In addition, a red warning light on the battery pack makes you visible from behind – in a team and at the roadside the difference between being seen and being overlooked.

What the Fenix HP35R delivers – and what it does not

The HP35R is built for continuous use in the field: IP66 means dustproof and protected against powerful water jets, the impact resistance is rated for a 2 metre drop, and the intelligent overheat protection throttles output before the housing becomes critical. IP66 is not, however, a diving rating – the lamp is not designed for prolonged submersion. Nor does it hold turbo indefinitely: the digital regulation keeps brightness constant, yet at high temperatures and when working close up the lamp dims automatically to avoid heat build-up and glare. That is by design, not a defect. For trail running or as a light tent lamp it is the wrong choice at 433 grams – its strength lies where long, bright runtimes matter more than every gram.

HP35R, the SAR version or a lighter headlamp?

Within the range you have a choice of head strap: the SAR version comes with a flame retardant rubber strap and is aimed at emergency services who have to reckon with sparks, heat or chemicals. The light, ventilated nylon version is more comfortable on long tours and sweats less. If you wear the lamp on a helmet anyway, you use the NVG shroud compatible mount and only need the strap as a backup. And if you honestly light up the near field most of the time – campsite, workshop, dog walk – then 4'000 lumens and 433 grams are more than you will ever need; our range of headlamps holds considerably lighter models for that. If, on the other hand, you search areas at night, work in caves or need hours of light with reserve, the HP35R is built for exactly that.

Who is the Fenix HP35R for?

The HP35R is for everyone who works at night rather than merely walking – and who has to see far and light up the near field at the same time, without recharging in between.
