Once it gets really dark, your eyes adjust and it doesn't take much light to see quite well. A Photon Freedom works for a short while and a 1xAAA LED such as the Peak Matterhorn provides a lot of light in the dark for walking down a hallway. Both are easy to EDC, but so many folks can't be bothered.
