The DieHard Slide Focus Headlamp is unlike many headlights in that it has a slide focus which allows you to change the light from a spot beam all the way to a flood beam and any point in between. Add in the high and low settings and you have a highly versatile headlamp with lots of light options. The light also tilts, allowing you to position the beam right where you need it. There’s also a back red safety light which helps you be seen at night. Light settings include high and low with 320 lumens on high. Other features include a 155 meter beam distance and 2.5 hours of run time on 3 AAA batteries. Even with all these features, the headlamp is still lightweight and comfortable to wear for hours on end. Three premium DieHard AAA batteries are included.
