My Uncle Artie wants a flashlight. He is blind. My brother Gabe says getting Artie an expensive light is a waste of money. He says a six dollar Ray-O-Vac will do just fine; with, or without, batteries. I say pride of ownership trumps need.This will be a Christmas gift. Artie is our favorite uncle. He is seventy-one, and helped turn our childhood into an adventure -(I hope all of you have an Uncle Artie). If you agree with me, what light do you recommend. I want something that can be carried in a pocket. Any thoughts on output and battery type will be appreciated.
