Great for campsite illumination, December 7, 2016 By Mike F. (Lancaster, PA)
On a transcontinental ride I found this filter to be useful in the remote campsites, particularly in western states where sites werenâ€™t affected/illuminated by any light pollution. The filtered light provides plenty of light to see around the camp. However, it doesnâ€™t desense vision like the white light from an unfiltered headlamp. This was particularly useful when transitioning from the campsites to moonlight walks, or just moving to the fringes of the illuminated areas of the campsite. This filter is useful any time you want illumination without losing the ability to see on a short venture away from the bike/campground.
