The NEO4 gives you the light you need for your nightly run. It is a compact and lightweight headlamp perfect for running, whether that is on the trail or road. It offers virtually non-glare optics with a wide beam so you can see further and be seen when on the move. The swivel-mounted headlamp lights the way with 240 lumens on energy savings mode for longer runs and 150 lumens on constant Current Mode, which provides constant illumination from start to finish. It features a rear red light and reflective headband so you can be seen from all directions. Additionally, it offers backup mode, meaning you know you've got 1 hour of battery life left after the first low battery warning, so you aren't suddenly stranded in the dark.
