Ultra-lightweight and high-performance, this 74g headlamp certified IP66 combines performance and practicality for all your lighting needs.

Quad-Core UHE MCT LEDs and Exceptional Color Rendering

The 2 quad-core UHE MCT (Multiple Color Temperatures) LED system with exceptional CRI of 97 (3000K), 83 (4500K) and 73 (6500K) offers faithful color rendering adapted to all weather conditions, ideal for optimal perception of the nighttime environment. Its dual-lens optical system with TrueVision+ technology and lighting angle greater than 100° delivers a wide, uniform and soft beam. Its dual button control (W for White, Y for Warm) allows intuitive control between neutral white, cool white, warm and red auxiliary light. Supplied with 2 HLB1500 1500mAh USB-C rechargeable batteries, also compatible with 3 AAA batteries, offering up to 14h30 of runtime depending on the mode chosen.

Professional Construction and Advanced Features

Designed for demanding runners and adventurers, the UT27 PRO combines durable polycarbonate materials in an ultra-compact and ergonomic format. Whether you run ultra trails, explore at night or camp in nature, this headlamp resists thanks to its protection against water splashes and dust (water-resistant but not submersible) and its resistance to drops from 1 meter. Its 90° tilt, phosphorescent compartment for nighttime battery changes, reflective and breathable headband, and diffuser bag offer maximum versatility to transform the headlamp into a camping lantern. An ultra-high-performance companion you won't be able to do without, always ready, never bulky.

Operating Instructions

The UT27 PRO lamp is equipped with two control buttons: W button for White LED (neutral/cool white) and Y button for Warm LED.

Power ON/OFF: When the lamp is off, a long press on the W button accesses neutral white light (LOW) (default setting) or cool white light (LOW). When the lamp is off, a long press on the Y button accesses warm light (LOW). When the lamp is on, a long press on either button turns it off.

Color Temperature Setting - W Button: The W button switches between neutral white light and cool white light. By default (factory setting), the lamp is set to neutral white light. When the lamp is off, perform a short press followed by a long press on the W button to turn on the lamp and switch between neutral or cool white light. The lamp automatically memorizes the last color temperature used.

Color Temperature Change: If neutral or cool white light is on, a short press on the Y button switches to warm light. If warm light is on, a short press on the W button returns to neutral or cool white light.

Brightness Level Adjustment: When neutral or cool white light is on, a short press on the W button cycles through levels: LOW - MID - HIGH. When warm light is on, a short press on the Y button cycles through levels: LOW - MID - HIGH.

TURBO Mode Activation: When any color temperature is activated, a double press on either button activates TURBO mode. A short press on either button returns to the previous state.

Red Auxiliary Light: When the lamp is off, double press on either button to access red light. When red light is on, a long press on either button turns it off. When red light is activated, a short press on either button switches between Constant lighting (CONSTANT-ON) and Slow flashing (SLOW FLASHING).

Lock/Unlock: When the lamp is off, press and hold both buttons simultaneously until the light flashes 3 times, indicating Lockout mode. In this mode, neither button can activate the lamp. If a button is pressed, the lamp will flash once. In Lockout mode, press and hold both buttons until neutral white light (LOW) or cool white light (LOW) turns on to unlock. Note: The lamp automatically unlocks if the battery is replaced while in Lockout mode.

Power Indication: When the light is off, briefly press either button and the corresponding power indicators will light up in turn and turn off after 2 seconds. Indicator status: 4 constant = 75-100%, 3 constant = 50-75%, 2 constant = 25-50%, 1 constant = 0-25% (Please recharge as soon as possible).

Battery Charging: The Li-ion HLB1500 battery is equipped with a USB-C charging port. Use the USB cable to connect an external power source to the charging port. Charging time: approximately 1h30 (Input: 5V/1A). During charging, the red indicator remains constantly lit. Once the battery is fully charged, the indicator turns solid green.

Battery Installation/Removal: Insert or remove the Li-ion HLB1500 battery or 3 AAA batteries respecting the polarity indications, then close the compartment until you hear a click.
