I have been carrying a Fenix PD22UE for a few years now. Works for me, tail clicky, CR123, 500 lumens on high. Several power modes.
I lost the clip one time, and contacted Fenix - they sent me a new clip and would not let me pay for it.
The model is no longer made, but unless I lose it I doubt I will have to replace it.
I previously carried a Eagletac D25 Ti - it was a great little light, but I wound up giving it to a friend in need.
I have a Foursevens Mini ML twisty which is a great, handy little torch. It is on a lanyard and I use it for camping, wearing it around my neck.
I also have a small "button" light, like a photo but a no-name variety I received as a bonus one time when I ordered Photons to give to the folks in the office for Christmas. It's nice to have a light on your keychain.
I have an inexpensive 4aa light in my truck that was given to me by a friend several years ago (Thanks Bill!) and it is still going strong.
Finally - I do have a Maratac Copper AAA - well made little light, sufficient for finding your way in the dark, but it is not very powerful.
I was on the Candlepower forums for several years before I found Bladeforums.....
