I purchased this head torch for my wife for running.
funny though i have been using it more as i am part of the Dartmoor search and rescue, and the lighting on this is great, we do training on wednesday evenings, all in the dark and the selection of lighting you have from the lowest to be able to read a map to the brightest, giving you good view of the ground at night, plus the distance is great, viewing the features in the dark, giving you an advantage as the directional beam you get, well i think i am going to have to buy one for myself, great product.
