NITECORE UT27 MCT (BLACK) - 800 LUMENS

An ultralight headlamp built for trail runners who run through changing conditions. At 74 grams, it delivers three color temperatures that adapt as you move from foggy mornings to technical descents to fast flat sections. The 1,500mAh rechargeable battery powers through dawn patrols and sunset runs, with AAA compatibility as backup.

THE FIRST HEADLAMP WITH THREE COLOUR TEMPERATURES AND THREE CRI OPTIONS

Cool, neutral or warm light up to CRI 97, all in a 74-gram headlamp that runs on a USB-C pack or AAAs.

• Three colour temperatures: 6500K cool, 4500K neutral, 3000K warm
• Three CRI options up to CRI 97 for true-to-life colour
• 800-lumen turbo reaching 168 metres from twin MCT UHE LEDs
• 74g complete, with a reflective sweat-channelling headband
• HLB1500 USB-C rechargeable pack, or 3 AAA batteries as backup
• Up to 14.5 hours of runtime, plus a red light for night vision
• Four-way clip for cap brim, pack strap or waist pack
• IP66 weather resistant, with a glow-in-the-dark battery door

MATCH YOUR LIGHT TO THE MOMENT, AND SEE TRUE COLOUR

Three colour temperatures. 6500K cool cuts through distance and fast terrain, 4500K neutral suits general use, and 3000K warm reads through fog and rain and is kind on the eyes around camp.

Three CRI options up to CRI 97. A high colour-rendering beam shows the world the way daylight does, so map detail, trail markers, a fish on the line, a wound or a wiring colour all read correctly. Most headlamps sit near CRI 70 and wash colour out.

800 LUMENS AND 168 METRES, HANDS-FREE

A TrueVision+ dual-lens system blends a wide near-field flood with a focused spot, so you light the ground at your feet and the terrain ahead at the same time. Turbo pushes 800 lumens out to 168 metres for spotting a marker, a ridge line or a far bank.

Four working levels sit below turbo, from a 100-lumen low that runs 14.5 hours to a 500-lumen high, so the beam fits a quiet campsite or a fast night descent.

74 GRAMS. YOU FORGET YOU ARE WEARING IT

At 74g complete, including the bracket, headband and battery, the UT27 MCT sits light and bounce-free on a long effort. The breathable headband channels sweat away and carries reflective elements so you stay visible to others on the road or trail.

Light enough that it stays on your head from dusk to dawn without the front-heavy nod that tires you out on a heavier lamp.

WHY THE UT27 MCT OVER AN ORDINARY HEADLAMP

Colour you can trust - CRI up to 97 renders true colour, where a typical CRI 70 headlamp flattens it. Map detail, gear, skin and wildlife all read correctly.

Three lights in one - Switch between cool, neutral and warm for the conditions, instead of living with one harsh tint that suits half your night.

Recharge or refill - The USB-C HLB1500 pack covers everyday use, and 3 AAA batteries get you home when you are days from a charger.

Wear it anywhere - The four-way clip moves it from the headband to a cap brim, a pack strap or a waist pack, and a stuff sack turns it into a camp lantern.

OFF THE HEAD WHEN YOU NEED IT ELSEWHERE

The included multipurpose clip mounts the UT27 MCT four ways: on a cap brim for a lower angle, on a backpack strap, on a waist pack, or back on the headband. The beam goes where you are working, not just where your head points.

A red light, constant or flashing, preserves night vision around camp and keeps you from waking a tent-mate or spooking wildlife. The glow-in-the-dark battery door helps you find and swap the cell in the dark.

THROUGH THE NIGHT, ON A PACK YOU RECHARGE

The included HLB1500 1,500mAh battery pack charges over USB-C and runs up to 14.5 hours at 100 lumens, enough for an all-night effort or several evenings out.

When you are far from a socket, drop in 3 AAA batteries instead and keep going. The pack swaps in seconds, so a spare gives you a second full night.

FOR EVERY KIND OF NIGHT OUTDOORS

Trail Running - 74g and bounce-free, cool light for speed on fast sections, warm light to read technical ground.

Hiking & Camping - AAA backup for multi-day trips, a warm beam and the lantern stuff sack for a calm camp, red mode in the tent.

Fishing & Wildlife - CRI 97 warm light shows true colour at the water or the hide, and red mode keeps your night vision and stays low-key.

Work & Repair - Hands-free high-CRI light on the cap or headband so wiring colours, finishes and fine detail read correctly.

FREQUENTLY ASKED QUESTIONS

What does CRI mean and why does CRI 97 matter?

CRI measures how truly a light shows colour, from 0 to 100. Most headlamps sit near 70 and make colours look washed out. The UT27 MCT reaches CRI 97 in its warm mode, so map detail, gear, skin tones and wiring read the way they do in daylight.

Can I run it on normal AAA batteries?

Yes, on 3 alkaline AAA as a backup for when you cannot recharge the HLB1500 pack. Rechargeable Ni-MH AAA are not supported, so use alkaline AAA or the included USB-C pack for full performance.

Can it be used as a lantern or worn off the headband?

Yes. The included diffusing stuff sack turns the headlamp into a soft camp lantern, and the four-way clip mounts it on a cap brim, a backpack strap or a waist pack instead of the headband.
