Nathan Neutron Fire RX Head Torch | Review

This specialist running headlamp is designed to light up the road or trail in front of you while ensuring you stay highly visible to oncoming traffic and other trail users

Why We Chose The Nathan Neutron Fire RX Head Torch: Lightweight, low-profile and compact, packing plenty of punch for its size

It’s important to be able to see and be seen when out running at night. And whether you’re heading out on your regular post-work 5k or upping your evening training mileage ahead of an upcoming race, you’re likely to face additional challenges as the day wanes. Put simply, when pounding pavements or running along dimly-lit backstreets, vehicles and cyclists need to know you’re there.

US running brand Nathan’s Neutron Fire RX running headlamp has been designed with just these scenarios in mind. It has a 360-degree reflective headband and a 160-lumen light output (or up to 200 lumens in ‘sprint’ mode) with five different lighting options, plus an unusual side strobe function that can illuminate in red, green or blue.

Who Is The Nathan Neutron Fire RX Runners’ Headlamp For?

Well, it’s for runners, obviously. The compact, lightweight design has a low-profile light unit and a slimline headband to minimise weight and bulk in use. With a max burn time of 25+ hours, it’s suitable for even the longest late-evening runs but is also a great grab-and-go headlamp for shorter sessions. So that embraces everyone from 5k trundlers to aspiring marathoners. The side strobe function and reflective headband mean that you should stand out in the glare of oncoming vehicle headlights – though, unusually for a road running headlamp, there’s no rear red light to warn cars coming up behind you that you’re there.

With a 160-lumen output on ‘high’ setting and a crisp white light beam, it’ll serve most trail and fell runners well too. If you need even more illumination, you can switch to a 200-lumen ‘sprint’ mode, which gives you a short boost of high intensity white light. If you’re into fastpacking or ultralight backpacking, you might also be attracted by this headlamp’s low weight and small pack size.


The compact light unit and integrated battery compartment is nice and light, with a low-profile, rectangular design. The body of the lamp is plastic, as is the retaining bracket that attaches it to the elastic strap, but it all feels pretty sturdy. The strap itself provides 360 degrees of silvery reflective print for all-round visibility that shows up well in the glare of streetlamps or car headlights.

There are two big buttons on top of the unit, which are used to control either the main LED or the RGB strips respectively. You need to press and hold either button to turn it on, and always remember that button 1 controls the coloured light while button 2 controls the white light. Single presses cycle you through the different brightness settings or the different colour options. It’s simple enough but does take a bit of getting used to.


When it comes to features, you get a crisp white LED spotlight with 5 lighting modes (low/medium/high/sprint/strobe), plus side strobes with RGB – Red, Green, & Blue – LED options. Although the main LED can put out up to 200 lumens, that only applies to the short-term sprint setting, so for general use in high power mode you’re looking at 160 lumens.

It’s powered by a rechargeable Lithium-Ion polymer battery, which is charged via a small USB port covered by a rubber flap on the side of the lamp.

The lamp is rated IPX4 weather resistant, which makes it splash-proof. We’d happily take it out on wet, rainy runs, but don’t dunk it in any puddles.


This is a neat little rechargeable headlamp that stands out from the pack thanks to those coloured LED side strips. It’s light and compact, which means it works well for runners, with minimal bounce, despite lacking some of the more sophisticated design elements of other, more expensive headlamps, like the Petzl Iko and BioLite HeadLamp 750.

It’s a little strange that despite being designed for road running, it doesn’t incorporate a rear red light, but the reflective headband and the array of coloured front lights should still keep you safe out there.
