Thanks for the excellent info, JohnK! I'm really starting to become a flashlight junkie, thanks to you guys on here, as much or more so than a gun, knife, sword/bayo, and optics junkie!
So far I have acquired, in quality lights
-Black Bear Borealis
-Black Bear Bear Cub
-Fenix L2T
-Surefire 6Z (2-CR123) (or is it a 6P - have had this one for years)
-Browning 4-AA light - not sure which model (this one is made by Pelican, it would appear)
-Black Diamond "Helion" headlamp
-Streamlight headlamp
-Streamlight TLR-2 pistol light/laser
-Streamlight keychain light
-Streamlight rechargeable home light
I'm getting a Fenix L0D (1-AAA) keychain light this week. My wallet says Curse ye scalawags and your expensive recommendations.
(though the Fenix's are quite the nice value).
P.S. Guys, FWIW, I'd recommend avoiding the Coast brand lights - I've had 2 that worked well at first, but turned out junky, particularly the flying saucer style keychain light.
