Context re my way of doing things:
- There are several items I carry on lanyards in my pockets while camping; a pocket knife and compass on one side, and a lighter, whistle, and micro-light on the other.
- I also have a Photon mini-light attached to my backpack's drawstring (sort of like a closet light in function, for when you're rummaging around and need to see better.)
- Over the years, I've forgotten some piece of gear at least once, including a headlamp. The tiny light got me through, and I've also made do entirely without a light.
- On most trips, short of full overcast and new moon, you'll have at least starlight and/or moonlight to see by, and once you get used to it, it's amazing how much you can actually see "at night" without a light. If you've never taken a hike under a full moon, you are missing something. Along the same lines, if you've never walked under just starlight and new-moon conditions, you are also missing something.
- My favorite ground cloth is a white piece of Tyvek, which has the added advantage of making it easier to see the things you lay on it in low-light conditions.
- Mostly, I prefer a Plowpoint tarp setup (early Spring/Fall, no bugs), or a hammock in summer.
All that said, I typically carry a Black Diamond Gizmo headlamp as my main source of light. It's 2.5 oz and runs on 2x AAA batteries. A spare set of batteries is pretty light as well.
I've tried candle lanterns, and while quaint/traditional (and they can warm up a small space), they simply weigh too much for what they provide (even with side and top reflectors), for me to bother with.
I have a Luci light, and that will occasionally go with me, especially if the trip isn't insanely hard portaging, there's a lean-to involved, or it's with a group. The LED color is a bit odd, but it provides a really nice overhead light for the entire interior. It's nice under my tarp as well. I consider it more of a luxury than a necessity for trips under a week long... longer, which I have never taken, I might lean more toward due to it being solar-charged (4oz vs 2.5 plus a change of batteries. The weight math works out in its favor at some point.)
I had a bear encounter years ago that had me rethinking what lighting was needed (at the time I had a broad-beam/diffused headlamp that couldn't reach out and touch anything at 50-75'). And for a long time, I carried a small flashlight/beam light, and eventually found one that weighs about 2oz, less than my Gizmo, and has a hat clip. But I like the hands-free utility of a headlamp, and the Gizmo is bright enough, and shines far out enough, that I seldom carry a small flashlight anymore. But it's a nice backup on a longer trip (vs say, a 1-2 overnight backpacking trip, where you can get by without.)
I don't go 'heavy' enough, or with enough people, to warrant a Coleman lantern. My dad used to use kerosene and propane lanterns at our off-grid camp when I was a kid, and I liked the quietness of the Kerosene ones, but they could be messy. Pretty sure we had a propane one in Boy Scouts too, especially at summer camp.
