Love it for use in camp shelters/remote cabins, December 7, 2016 By Mike F. (Lancaster, PA)(Verified)
I use this filter at the end of the day as general illumination for my campsite. Rather than having a hotspot, this filter gives a more even distribution of light. Outside I aim the light to the ground in front of the bike. In shelters, I do bounce-illumination by aiming the light at the walls or, most often, ceiling.
I find this filter works best in shelters, and the Red Filter works best outside, where you donâ€™t want to desense your eyes as you move around the campsite while keeping your lamp fixed to you bicycle.
