Thank you all so much for your help. I've found 3 good ones in our area, and we'll be out tomorrow night for a hike!

One of the famous night caches here has the reflectors up high on the trees. You can only see them if you hold your flashlight above your head, so the light hits the reflector more directly. There were several of us on that adventure, and the best flashlights turned out to be the non-LED types. If I had been trying to do that cache by myself, I would have been wandering the woods until dawn.
I covet a friend's very bright, compact flashlight . . . but it costs about $60.00 . . .
Definitely take more than one flashlight/headlamp, and extra batteries.
LIke I said above, the 1W - 5W LED lights with a SINGLE LED work great. The multiple LED lights don't do much for me at all. I bought a non-LED light for my son but he's a CHP officer and needed a good tactical light. Boy, those things can get very expensive!
