I have too many to list each one, but I will tell you which ones I like best and why:

I EDC an ARC Premium. An amazing amount of light in a tiny package.

While camping I much prefer plastic bodied lights over metal bodied lights. They don't scratch the snot out of other gear, they are much warmer to hold in cold weather, and they are usually brighter which gives me a better chance of finding them if dropped in the dark (happened to me just last weekend).

My favorite light overall is my Princeton Tec EOS LED headlamp. Thel headlamp are sooo much easier to work with - they leave both hands free, magically look in the direction I'm looking, and the EOS is plenty bright for camping uses but has a dimmer setting that conserves batteries and is more than sufficient for in-tent use.

I also carry a Uunderwater Kinetics 4 AA LED light in my pack. It essentially acts as a backup to my headlamp. The beam pattern is just the right width for ease of walking trails and lighting up objects in the nearby work area. My only problem with this light is that its switch is a bit finicky and has to be pushed just right to work. I have four of these lights and they all act the same way.

For around the house, where i may need longer-range viewing, my favorite is the Streamlight ProPolymer 4AA LED. It has a very strong beam. This is the light my kids carry with the Scouts since it is powerful and the switch is much easier to use than the UK 4AAA LED's.
