520 Lumen Dual Beam Headlamp

The NITECORE UT27 is an ultra-lightweight headlamp designed for trail running and tested and proven in the field by trail running athletes. The UT27 features a bright 400 lumen spotlight warm LED that minimizes glare and a cool white 200 lumen wide angle flood to illuminate your entire field of vision. It is supplemented with a red light, perfect for camping, backpacking, stargazing and a flashing mode for emergencies and enhanced visibility. You can switch among these lights and adjust the brightness on the go with the easy to use dual switches.

Rechargeable with Dual Fuel Options

The UT27 comes with a HLB1300 battery pack with a built-in USB-C slot that can be fast charged outside of the UT27. While you are charging the battery you can stay on the move by using a backup battery or 3x commonly available AAA batteries. The HLB1300 can be fully recharged in an hour and a half, and last over 13 hours on low. Camping, hunting, or hiking at night? The glow-in-the-dark battery compartment keeps you locked on while swapping batteries for your headlamp.

Comfortable to Wear

Built on a durable yet compact frame, the UT27 weighs only 2.61 ounces with battery and headband included. The breathable lightweight headband has a built-in silicone strip that firmly secures the UT27 while helping divert sweat away from the eyes. Reflective decals provide additional visibility to motorists, making it safe for nighttime walking, running, or jogging. The Nitecore UT27 isn't just a trail running headlamp; a handy companion to keep you illuminated in all situations.

5 of 5 First Nitecore November 30, 2022
Reviewer: Jacob  
Great light. Was looking for a multipurpose light. Primarily we use them for late night or early morning dog walks. Secondary for better visibility when doing outdoor runs. The multi battery option is great. Charge up the pack and keep some AAAs handy just in case. Double levels of brightness for spot or wide flood are a great option.

5 of 5 Fantastic running light - lightweight June 6, 2022
Reviewer: JacklynJack Vasko from Philadelohia, PAWallingford, PA United States  
They’ve improved the headband over the years a d this one stays adjusted properly and fits nicely.  I love the lightweight.  I do wish there were two brightnesses on the red light.  Pretty intuitive controls.  Pretty bright.  Wish you could charge it without opening the batter compartment, but I’m sure that would add weight.  At least the battery compartment opens with a simple tab instead of screw off cap.  Makes it faster to access for charging

3 of 5 UT27-Pretty good but could be better February 17, 2022
Reviewer: Drew Jardine from Big Sur - CA  
Overall I like the headlamp…But it could be better. I prefer the old tried and true NU25 -( I have purchased four -two white/ two yellow but all have disappeared somehow =( )  the NU25 is much more comfortable to wear long term. I do not like the UT27’s bracket sitting on your forehead, it’s uncomfortable and feels like it’s digging into my skin. I’m constantly messing with it and the strap is also strange and and doesn’t seem to stretch or move through the adjusting strap wellAnd has come apart on me several times already while adjusting it. The light output is great, battery life decent.
However my UT27’s hinges on the battery case housing have somehow broken and cracked already in about a month of light use. so I’m going to have to return it for a warranty exchange.
