I use a Fenix headlamp when riding my bicycle. Like amper I have my light tilted down to light about 3 meters infront of the front wheel. I use 150-200 lumens. I ride in mostly well lit up city area so no need for far reaching light, itīs enough to light up 2-3 meters in front of me. Havenīt noticed anyone being blinded by my light and looking at my reflection in windows I donīt find my light disturbing to the eye. .
