Consider getting an LED headlamp instead! They come in all different flavors including very powerful ones, and waterproof ones. I use them for all my backpacking and fishing these days, but even at home during power failures. I mostly use the bulky and expensive handheld I have at home - easy to find by feel - only to locate one of my head lamps in the dark.
Beyond that advice getting more specific would depend a bit on exactly how you want to use one for either style. I always have a few in my bag when fishing. For everyday stuff like breaking down and stowing gear and walking on trails the smaller, lighter, cheaper ones are probably best. But if you are trying to see Bigfoot walking by 50 feet off then there are stronger ones that have different setting for brightness, diffusion level, color (red is supposed to be better for contrast and hence reading a map etc) and so on.
Thank you for the input. A headlight is not an option. I would prefer a really compact pocket light with good power. But have seen models with holders so you can also put on your basecap. Good point...
My daughters gave me an Olight S2R Baton II for Christmas. I've owned many but this one is pretty cool - powerful (1150 lumens), light, rechargeable, hat clip, and wrist lanyard. You're going to like it!!
The other thing to consider is a diving-scuba light that is WATERPROOF. I have been meaning (in my personal blog) noted my excessive light collection that Judy and I rely on .. where it is on a paddleboard on the flats, or wadding my local river for smallmouth bass.
