My TL-3 is not getting a lot of use. It is very bright, has a nice beam and is well made, but the 3x123 format is just too long to haul around comfortably. It might just be me, but I also don't like the way that the batteries rattle when the switch is backed out to the momentary or off postitions.
I also think I have about all the lights mentioned in this thread. The Scorpion is my current favorite. Not quite as much throw as the PM6, but a little smaller and still very bright. The PM6 is built like a tank (a Swiss tank!). The Spyders are cheap and bright and worth twice what I paid for them. The don't have quite the output of the other lights mentioned and have an annoying shadow from the bulb pins in the beam. Great glove-box lights.
My next acquistion will be a G2. I really like the idea of the P-60/90 lamp options and the light weight. Add some R-123s and a BugOutGear LED drop-in, this should be very flexible package. It will probably replace the Scorpion in my briefcase.
