UltraFire AB-T60 XM-LT6 3-Mode 910-Lumen White LED Flashlight - Black (1 x 16340)

Pros: It's well made and finished. Bezel won't shred your pocket.
Has springs in both ends of the battery compartment, will fit any 16340, protected or not.
Bright. I don't have other flashlights of this caliber, so I compared it to the brightest light I could find right now:
It's about the same power as a fresh Yamaha motorcycle headlight. I kid you not. I should get a handlebar mount and double my lights..

Cons: I'm still on my first battery, but it can't last long. I specifically wanted a single 16340 powered one to fit in my pocket, but I'm sure I'll be changing batteries frequently.

Other: This thing packs a lot of light into a small, reasonably prized package. I like it.

Pros: Small and easy to use and carry, exellent size for my rifle, the tailcap came with enough space to reach the "on" button, light and comfortable to carry, the front doesn't get to hot when is working continiously.

Cons: Difficult, doesn't work for more than 45 or 50 minutes with such small battery, a nice complement would be an extention for an extra battery.

Other: Small and easy to use and carry, exellent size for my rifle, the tailcap came with enough space to reach the "on" button, light and comfortable to carry, the front doesn't get to hot when is working continiously.

Pros: very light and easy to carry, very strong and abuse resistance, very usefull for hunting or any other use.

Cons: Due the small battery it run out quickly, is very helpfull to carry a couple of spare batteries to enjoy this little monster for a while longer.

Other: Small, light weight, incredible powerfull, weeka battery model, fair price.
