WHY ULTRA AND NIGHT RUNNERS REACH FOR THE UT6
The right light for every stretch of course
Warm, neutral and cool channels on three buttons. Switch from forest to fog to open ridge with one tap, mid-stride.
Ground you can read
The 3,000K warm channel reads CRI 98, so roots, mud and wet rock keep their real colours and the next foot placement is easier to judge.
Race-night weather is covered
Submersible to 2m and rated from minus 40 degrees, so a tropical downpour or a cold alpine start is part of the plan.
Power that matches your distance
Top up over USB-C from the power bank in your vest without breaking stride.
One headlamp, three light qualities.
Eight dual-core MCT UHE LEDs give the UT6 three separate colour channels. The 3,000K warm channel cuts through rain and fog, the 4,500K neutral channel suits technical trail, and the 6,500K cool channel pushes light out across open ground.
Each colour temperature carries its own CRI: 98 on warm, 85 on neutral, 73 on cool. Low-CRI light flattens a trail into one grey tone. The warm channel keeps the contrast between dark soil, slick rock and tree roots, which counts most on a tired descent in the small hours.
Full 1,600 lumens on every colour, not just the cool one.
The UT6 reaches 1,600 lumens and a 195m throw at 9,508 candela on all three colour temperatures. The brightness holds whether you are running warm light through fog or cool light across open terrain, so the light follows the conditions instead of the other way around.
A flood beam over 100 degrees fills your whole field of view at close range, while the throw still picks out a marker or a trail junction well ahead of your feet.
Two nights of light, set and forgotten.
The included 4,000mAh NL1840R battery runs the UT6 for up to 31 hours at 150 lumens, enough to carry an all-night ultra from dusk to dawn with charge to spare.
The Rapid Reel headband sets the fit with a single one-handed turn, and a near-centre-of-gravity quick-release bracket holds the unit bounce-free over your forehead, so the beam stays steady from the first mile to the last.
Aim the light where the next step is.
The head tilts up to 45 degrees with a quick one-handed adjustment, so the beam points at your feet on a descent and lifts to the path ahead on a climb. Whether you are picking a line up a scramble or reading the ground on a steep trail, the light goes where you are looking.
Magnesium-alloy build, lighter and tougher.
The body is magnesium alloy, around 30 percent lighter than the same shape in aluminium, paired with a high-impact PC front shell and a reinforced composite bracket. That mix pulls heat away from the LEDs and shrugs off knocks, while keeping the whole headlamp at 130g.
It is built to take a season of training runs, race nights and drop-bag handling and keep performing.
Rain, mud and a dropped-in-the-creek moment are all a non-event.
The UT6 is rated IP68 and submersible to 2m, so a downpour, a stream crossing or a headlamp that ends up in a puddle does not stop the night. It is also drop-rated to 2m, the kind of fall that happens when it slips from your hands at a checkpoint.
Rinse it clean under the tap after a muddy run and carry on. The sealing is built for the trail, not just a light shower.
Reliable from alpine cold to tropical heat.
The UT6 is rated to operate from minus 40 to 45 degrees Celsius. That covers a freezing alpine start, a humid tropical night and everything between, with the output holding steady under your feet.
Train at home, race overseas, and the headlamp behaves the same on every start line.
Recharge it, or swap it, and stay on the trail.
The built-in NL1840R 4,000mAh battery charges directly over its own USB-C port, so you can top it from a wall plug, a laptop or a power bank in your pack while you keep moving. No separate cradle to carry.
When a 100-mile night needs more, the quick-release bracket lets you drop in a fresh cell in seconds and carry on at pace, instead of stopping to wait on a charge.
Slide between runtime and power, and lock it for the pack.
A three-position slider sets the whole headlamp at once. Long-Runtime mode stretches the battery for a long, low-effort night, and High-Performance mode unlocks full output when the pace or the terrain calls for it.
Slide it to Lockout before the UT6 goes in a bag and the buttons stop responding, so it cannot switch on against your kit and drain the battery before you reach the trailhead.
The MCT UHE LED system, on three intuitive buttons.
The eight dual-core MCT UHE LEDs sit behind a unibody multi-faceted optical lens with over 94 percent light transmission, which is how one head unit delivers three colour temperatures at full brightness.
Each colour gets its own button: the W button for cool white, the centre button for neutral white, and the Y button for warm light. There is no scrolling through a menu, so on a fast descent you tap straight to the light you need and keep your eyes on the trail.
WHERE THE UT6 EARNS ITS PLACE
Ultras & 100-Milers
Bright enough for a technical descent at 3am, with a beam that stays steady over the full distance.
Night Training Runs
It rides bounce-free at tempo pace on the after-work loop.
Multi-Day Treks
Long-Runtime mode stretches one cell across several evenings of camp and trail.
Camp & Hiking
The stuff sack diffuses the beam into a soft lantern glow for the tent.

FREQUENTLY ASKED QUESTIONS
Can I charge it from a power bank, and can I carry a spare battery?
Both. The built-in NL1840R 4,000mAh battery charges directly through the headlamp's USB-C port, so a power bank in your pack tops it up while you keep moving. The quick-release bracket also lets you swap in a fresh cell in seconds, which is how runners carry a spare to get through a 100-mile night and keep their pace. For cold-weather use, the all-weather NL1840AW (4,000mAh, 10A) is a compatible spare that holds its capacity down to -40°C.
How do I stop it switching on inside my pack?
Slide the mode selector to Lockout before you stow it. In Lockout the buttons stop responding, so the UT6 cannot turn on against your gear and arrive at the trailhead with a flat battery. Slide back to Long-Runtime or High-Performance when you are ready to use it.
