Hi guys, I got my Mum a iTP A3 EoS and succeeded in converting her to an EDC mindset, at least in part. However for Xmas this year she has asked me if there is a lighter weight option she could turn too. The iTP is all she has on her keys, other than keys, and finds it too heavy. She is a teacher and uses it to get to her car a night when leaving work, there is a lot of outdoor stairs at her school, and not much lighting. So without resorting to specialist battery types like 10180s what would be the best, or more importantly the brightest light I could get her. I'm guessing the Photon? anything I haven't though of?
