A 2,000 lumen trail headlamp powered from a battery on your pack, so the light lasts the whole race.
For ultra runners and long night efforts. A light lamp on your head, the battery behind it or in your vest, and up to 55 hours from the power bank in the box.
- Split-type design: a 122g lamp up front, the power bank at the back of your head or in your pack
- 12,000mAh Carbon Battery 12K included, and any suitable USB-C power bank works too
- Three colour temperatures, each up to 2,000 lumens: 3,000K warm, 4,500K neutral, 6,500K cool
- Reaches 220 metres down the trail
- Long-Runtime and High-Performance modes on a slider
- Built-in backup cell keeps you lit for about 30 minutes while you swap power
- IP68 rated, submersible to 2 metres, impact resistant to 2 metres
Choose the battery to suit the race.
Conventional headlamps lock you into whatever cell fits inside them. The UT2000 runs from a power bank on a detachable USB-C extension cable, so the size of your battery follows the length of your event rather than the size of the lamp.
It ships with the Carbon Battery 12K. For a 50km evening loop that is plenty. For a 100-miler you can plug in a larger power bank and carry it in your vest.
Weight balanced front to back.
With the included power bank on its rear bracket, the lamp at the front and the battery at the back counterweight each other. The whole setup stays level and steady on a fast descent, where a front-heavy headlamp starts to bounce and tip.
The full head-worn rig weighs 310 grams with the power bank, bracket and headband.
Or take the weight off your head entirely.
Run the extension cable into your vest and the only thing on your head is the 122 gram lamp and band. Your neck carries less over thirty hours, and the battery rides where you were already carrying weight.
The same cable takes a higher-capacity power bank when the race calls for it. For the top Turbo level, use one rated at 20W or more with PD support.
Keep the battery warm and it keeps its charge.
Cold drains a battery fastest when it sits exposed on your forehead. With the UT2000 you can tuck the power bank inside your pack or close to your body on a high, cold section, where it stays warmer and holds its output.
That matters on an alpine night stage or a pre-dawn summit push, when the light is the last thing you want to fade.
Light the trail out to 220 metres.
At its top output the beam reaches far enough to read the line of the next switchback and spot a course marker before you arrive at it. A large-angle flood with soft edges lights the ground at your feet at the same time, so you see the rock you are about to step on and the turn after it.
On runnable ground, 350 lumens covers you comfortably for up to 26 hours in Long-Runtime mode.
Three colours of light for three kinds of trail.
3,000K warm light at CRI 97 cuts through fog, rain and snow, where a cool beam bounces back into your eyes. 4,500K neutral at CRI 83 shows the texture of steep, muddy or snowy ground for technical sections.
6,500K cool white at CRI 73 is the bright, efficient choice for flat, open terrain and long-range route finding. Each one reaches the same full output.
Eight dual-core LEDs make it possible.
The UT2000 runs eight dual-core NiteLab MCT UHE LEDs. Each pairs a high-CRI core with a high-efficiency core, which is how one lamp shifts both colour temperature and colour accuracy from the same eight emitters.
A multi-faceted TrueVision+ optical lens blends them into one even field, so whichever colour you choose fills the whole beam.
A slider for how you want to spend the battery.
Long-Runtime mode stretches the power over the distance, giving 55 hours at 180 lumens for long night races and sections far from an aid station.
High-Performance mode steps down more gently and holds a higher average brightness, which suits fast running, technical ground and poor visibility. Slide between them on the move as the course changes.
One button per colour.
Three buttons on top each control one colour temperature: W for cool white, N for neutral and Y for warm. You go straight to the light you want instead of cycling through modes with cold, tired fingers.
When fog rolls in at kilometre 80, one press gets you warm light. That is the whole interface.
It stays lit while you change batteries.
A small 40mAh cell sits inside the lamp. When your power bank runs low, or you unplug it to swap, the UT2000 switches over automatically and gives you about 30 minutes of emergency light in the colour you were using.
You keep moving through the swap on a dark trail. Once you switch that emergency light off, it stays off until you reconnect, so plug a fresh power bank in at the next chance.
Built for mud, rain and a fall on rock.
The lamp is PC and aluminium alloy, rated IP68 and submersible to 2 metres, so an all-night downpour or a stream crossing is within its rating. It is impact resistant to 2 metres.
A red rear light on the band makes you visible to the runner behind you and to traffic on a road section.
A camp lantern when the running stops.
The included diffusing stuff sack stores the headlamp between runs. Turn the lamp on inside it and it becomes a soft, room-filling lantern for a tent or an aid-station checkpoint.
A clip also comes in the box, so the lamp can be fixed to a pack strap or a belt when a head mount is not the right fit.
WHY THE UT2000 OVER AN ORDINARY RUNNING HEADLAMP
Runtime you set yourself
An all-in-one headlamp runs for as long as its small internal cell allows. Here the runtime grows with whatever power bank you choose to carry.
Light that suits the weather
Three colour temperatures, including a warm, high-CRI setting for fog and rain, where most running lamps offer a single cool white.
No dark gap on a swap
An internal backup cell bridges the change of power bank, so changing batteries mid-race is something you do while still walking.
Tested numbers
Output, throw and runtime are measured to ANSI/PLATO FL 1-2019, so the hours you plan your race around are the hours the lamp delivers.
WHO IT IS BUILT FOR
Ultra & Trail Runners
A light that lasts 100km and 100-mile nights, balanced on the head or with the battery moved into your vest.
Night Hikers & Trekkers
Warm light for misty ridges, neutral for broken ground, and a power bank that also charges your phone.
Alpine & Cold Weather
Keep the battery inside your layers on a cold summit push, where an exposed cell would fade.
Multi-Day Campers
The stuff sack doubles as a tent lantern, and the included power bank keeps the light and your devices going for days.

Which mode should I use for a 100km race?
Long-Runtime mode. On the included Carbon Battery 12K it runs 26 hours at 350 lumens and 55 hours at 180 lumens, which covers most finishing times with margin. Switch to High-Performance for short technical or foggy stretches, then back.
Will my own power bank reach the full 2,000 lumens?
Only if it puts out 20W or more and supports the PD fast-charge protocol. A smaller power bank still runs every other level, and Turbo simply stays unavailable. The runtime figures on this page are measured with the Carbon Battery 12K, so other power banks will give different hours.
What happens if the power bank runs flat mid-run?
The headlamp switches to its internal backup cell on its own and keeps the current colour on for about 30 minutes, which is time to plug in a spare or reach an aid station. Keep it on until you reconnect, since switching the emergency light off ends it.
