Tailored lighting modes for any situation.
This headlamp goes beyond the basics to give you the right light for every condition.
The UT27 Pro offers The cool white beam provides crisp brightness, ideal for spotting details and navigating dark paths. The warm light mode reduces glare, cutting through fog, rain, and mist for close-up tasks in low-visibility conditions. Together, they create a balanced beam that eases eye strain and improves depth perception, perfect for varied terrain and extended use.
The red light modes offer low-impact illumination when subtlety is key. A constant red light preserves night vision, making it useful for reading maps or moving discreetly without disturbing wildlife or others nearby. The flashing red light functions as an effective emergency signal, helping to ensure safety during rescue situations or low-light work environments.
Built for lasting performance, the UT27 Pro runs up to 10 hours on its rechargeable battery, with the flexibility to switch to 3x AAA batteries if needed. This dual-power setup means you’re prepared for extended missions, fieldwork, or any setting that requires a dependable light source.
If you’re looking for a headlamp that adapts to your needs, the UT27 Pro delivers reliability and versatility wherever you go.
