Until an hour or so ago my 6D Maglite was on the "worst" list.
Not that it's a "bad" light, it's just that the thing is awkward and overly heavy and had been put into storage. Well, while putting away some laundry I was trying to tuck some matched socks together, and was having heavy sledding. My hand isn't exactly small, and the socks weren't very flexible, and that second sock was a BEAR! Light bulb moment! - I grabbed the 6D from the closet shelf and started using it. All of a sudden the job was quickly finished. I've found a job (sock tucker) for my "worst" light, and someday I may even find a lighting-connected use for it. Best? More like "favorite", and that's my 6C Maglite. I'm also highly partial to an inexpensive older Eveready LED flashlight with a regulation circuit. When most of my other flashlights have gone totally dark, that one sucks another hour or two of good light out of their batteries.
