Like Turtle, I use a small LED light that clips on my ball cap for 90% of my lighting needs. Unfortunately it is a white light. In my hammock side pocket I keep another tiny LED (that won't clip on my hat, alas) which is red, for those late night trips to pee, or down to the waters edge to star watch, without losing night vision.
Seeker, I use a UCO mini candle lantern in the fall, which holds a tea light candle. I rarely make a fire, but the candle lantern really cheers up the site. And once, I got turned around in the bush behind a campsite, but the glimmer of the lantern guided me home. I used to use a bigger UCO lantern which holds a wax candle, but I found it too heavy for backpacking. They call me a gram wheeny---I am!
