Ultimate Survival Technologies Brila 450 Headlamp Capable of 26 Hours of Runtime & 450 Lumens of Light The UST Brila 450 Headlamp is so-named thanks to its 450-lumen brightness capacity that can illuminate your view wherever you're headed next. Great for those who walk or run in darkness, for whom this headlamp will pathfind for more than a full day continuously, with a 26-hour maximum runtime. 6 Light Modes Activate Single-Handedly Variable brightness settings empower you to navigate a whole range of light conditions. From an overcast day to the pitch black of night, the Brila 450 will always keep you trekking. Also features a light that will automatically flash a Morse code S.O.S signal for emergency situations. Red Light Feature Multiplies Functionality Two of the Brila 450's light modes emit soft red light that is handy for many situations, including early-morning fishing trips where white light would startle away fish and fresh tackle. Red light conserves battery to reach the maximum runtime and preserves your natural night vision while still providing you with valuable illumination.
