UT27 MCT - CRI comparison - Nitecore Singapore

Match your light to the moment. Three color temperatures for every trail condition.

SEE TRUE COLORS IN HIGH-RISK CONDITIONS - The 3000K warm light with CRI 97 renders colors accurately in rain, fog, and snowfall. When you're navigating technical terrain in low visibility, see trail markers, rocks, and roots in their actual colors.

BALANCE CLARITY AND EFFICIENCY FOR TECHNICAL TERRAIN - The 4500K neutral white light with CRI 83 gives you sharp detail on steep slopes, muddy sections, and snow-covered trails. Get the visibility you need for quick route decisions during stream crossings or scrambles.

MAXIMIZE BRIGHTNESS FOR EVERYDAY RUNNING - The 6500K cool white light with CRI 73 delivers superior output and extended runtime for regular training runs and urban night sessions. Cover familiar routes with efficient illumination that lasts the entire run.

PRESERVE NIGHT VISION WHEN IT MATTERS - Switch to red light when you're reading maps, setting up camp, or need to signal without disturbing other runners. The constant mode keeps your eyes adjusted to darkness, while the flashing mode works for emergency signaling.

POWER THROUGH LONG RUNS WITH DUAL BATTERY OPTIONS - The included HLB1500 rechargeable battery delivers up to 14.5 hours on low settings - enough for overnight races and multi-day adventures. Need backup? Pop in three AAA batteries you can find at any convenience store.

BARELY NOTICE IT'S THERE - At 74 grams with battery included, this headlamp weighs less than a energy gel flask. The breathable headband includes a silicone strip that channels sweat away from your eyes, keeping you comfortable through hour six of a ultra.

UT27 MCT - Dual Power - Nitecore Singapore

Built for the demands of ultra-distance trail running.

When Every Gram Counts and Every Hour Matters

You're 14.5 hours into a 100K, pushing through pre-dawn darkness. The UT27 MCT is still running strong on a single charge, weighing less than the energy gels in your vest.

This isn't just lighter than your previous headlamp - at 74 grams with battery, it's designed for runners who measure gear weight the way they measure pace: precisely, because it matters over distance.

The TrueVision+ dual-lens system with over 94% light transmission creates a 100+ degree flood beam that illuminates your entire field of vision. You see the trail ahead, the roots to your left, and the rocks to your right - all in one soft, uniform light that doesn't strain your eyes during night sections.

Two quad-core MCT UHE LEDs deliver 800 lumens reaching 168 meters when you need to spot distant trail markers or navigate unfamiliar terrain in the dark.

The glow-in-the-dark battery compartment means you can swap power sources during a midnight aid station stop without fumbling with a headlamp or phone light.

Ready for runs that start before dawn and finish after dark?
