UT6 - 1600 lumens

1,600 lumens and three colour temperatures, in a 130g headlamp built for the long night out. One head unit gives you a warm CRI 98 channel for true colour, a neutral channel for technical trail, and a cool channel for distance, all on a USB-C rechargeable battery you can swap in the field. 1,600 lumens and a 195m throw across all three colour temperatures 3,000K warm (CRI 98), 4,500K neutral (CRI 85) and 6,500K cool (CRI 73), each on its own button 8 dual-core MCT UHE LEDs behind a wide flood beam over 100 degrees Built-in NL1840R 4,000mAh battery, USB-C rechargeable and field-swappable Up to 31 hours of light on Low in Long-Runtime mode Magnesium-alloy body, IP68 submersible to 2m, drop-rated to 2m Rapid Reel one-handed headband and a head that tilts up to 45 degrees 130g complete, with a three-position slider for Lockout, Long-Runtime and High-Performance WHY OUTDOOR PEOPLE REACH FOR THE UT6 Three lights in one head unit Warm, neutral and cool channels on three buttons, where an ordinary headlamp gives you a single fixed tint to live with. Colour you can trust The 3,000K warm channel reads CRI 98, so skin, maps and materials look true. Most headlamps sit far lower and wash colour out. It keeps going underwater and in the cold IP68 submersible to 2m and rated from minus 40 degrees. A splash-only headlamp stays in the bag when the weather turns. Power you can refill or swap Charge the battery in place over USB-C, top it from a power bank mid-trail, or click in a fresh cell to outlast a 100-mile night. 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. The warm CRI 98 channel renders colour close to daylight, so when you are inspecting a finish, matching paint or checking a wound, what you see is what is really there. 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 see through two full nights of camp or trail before a recharge. 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 the kind of build that takes a season of trail, camp and pack abuse and keeps performing, rather than feeling like a unit you have to baby. 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 off a tent peg or a tailgate. 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 cold alpine bivvy, a winter night shift and a humid tropical trail while the output stays steady under your feet. It is built to perform across the conditions a year of outdoor use throws at it, so the headlamp behaves the same on every trip. 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. WHO THE UT6 IS BUILT FOR Camping & Hiking 31 hours on Low covers two nights of camp chores and trail finding, and the warm channel keeps your night vision soft around the tent. Trail Running 130g and a Rapid Reel fit stay bounce-free at pace, with three colours on three buttons to match forest, fog and open ground. Close & Creative Work The 3,000K CRI 98 warm channel renders colour close to daylight, so paint, prints and finishes read true under hands-free light. Work & Trades IP68 sealing and a minus 40 degree rating hold up on a wet, cold site, and the 45 degree tilt aims the beam into the job.

Yes. The 3,000K warm channel renders colour at CRI 98, which is close to natural daylight. For tasks where colour matters, such as matching paint, inspecting a finish, checking print or reading skin tone, that high CRI shows the true colour rather than the muted, off-tint look most headlamps give. The neutral and cool channels trade some colour accuracy for higher visual brightness when you want reach over fidelity. 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. 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.
