I Need to find a 5.5 " led light that runs off AAA batteries. About a .5"-.7" diameter head that can be stored in a back pocket. I carry my keys for work on a kubaton and was thinking of replacing it with a useful light. The dorcy has a 45 lumen light that seems cheap and I was wondering if there is anything out there with better quality. I put great faith in your advice as I have purchased my past 2 lights based on your recommendations. Thanks in advance...
