Ah, lights!

Yet another hobby for which I wish I had more money and time.
For woodsbumming I used to (and still could!) get along fine with my 2AA LED maglite, great basic light for the price. I have since upgraded to a Fenix Q5 L2D for my designated hiking light, it is always in a sheath on my daypack. I do still use the 2AA maglite on occasion though

On my nightstand I have a Surefire G2 LED, and in the living room I have a 4D Maglite.
I also have small lights sprinkled around my hiking gear and EDC/around the house stuff. I have Fenix E01s on my keychains and in my PSKs, $1 LEDs from county comm floating around, some cheap $1.50 supposedly solar powered LEDs from China on my daypack strap and on a few other things, and Nite Ize Spotlit LED carabiner LED lights from county comm that are great as markers for people and gear at night (blink and steady modes).
I went with the Fenix Q5 L2D as my primary outdoors light for several reasons:
-Multi-mode and regulated output (constant 180 lumens for 2.4 hours on Turbo and constant 12 lumens for 55 hours on lowest, with various other levels and settings in-between. I actually think the SOS and strobe are nice extra features to have on an outdoor light.)
-Waterproof up to at least 2 meters for 30 minutes or something like that
-2 AA batteries (I pack extras with me, but nice to be able to use batteries I can find at the corner store)
-Reputation and the experience of others
-Price (Wish I held out for the LD20 though!)
-It's a clicky
-Unobtrusive and lightweight
I don't have any pics of most of my lights though, sorry

You can see some beam shot comparisons of the Surefire G2 LED, Maglite 2AA LED, and Maglite 4D in addition to some pics of the Spotlit carabiner LEDs
here. (Those are the ones I did for you Fonly

)
I do need to pick up a good EDC light though, since all I carry is a Fenix E01 on my keychain and little gerber light in my backpack. I've had my eye on the Surefire E2D LED Defender, Fenix TK11, or Fenix TA30. The TA30 looks like it'd make a good hiking light as well (9 lumens for 115 hours at lowest, and 225 for 3.5 hours at highest):thumbup:

I know next to nothing about headlamps, but am planning on researching them and trying one out this year.
