Left to right: Fenix, Energizer, Lenser/Coast, and Dorcy. All three penlights take two (2) AAA batteries.
Penlights have, I think, reached their zenith with the development and production of the The Fenix LD05 "High-Intensity Penlight." Is it possible to get more than 100 lumen out of two AAA batteries and still have anything remotely resembling a reasonable run time at that power setting? Probably not.
Several entries below, just back to December 7, 2010, you will see a trio of penlights. You can find that here in case you don't want to fumble around.
Here is some of the information on this excellent penlight from The Bright Guy's Website:
"The Fenix LD05 is a high intensity penlight with 3 brightness levels and 100 lumens in high. The Fenix LD05 measures only 5.9" long and runs for up to 23 hours on common AAA batteries, either alkaline or rechargeable NiMH. The LD05 is a convenient pocket-sized flashlight with a sleek design and durable construction - the perfect LED flashlight for home and work.

Well, I wish it was Made in The Good, Old U.S. of A., but you can't have everything these days. It is Made in China. It's getting harder to find stuff that you either want or need that isn't Made in China, that's how it goes now.
The wonderful news is, Fenix is demanding high-quality and it shows. I have had a couple Fenix lights for a few years now and they really are excellent flashlights.
This penlight is a little bit longer and heavier than a common Sharpie marker but it has come in handy so many times. Even in daylight hours at work trying to find serial numbers on pieces of equipment in a dark corner of a storage room. It is light enough that you will not notice it after a while. Excellent piece of gear, a little bit pricey for a penlight but it's a penlight that will blast out 100 lumen for approximately 90 minutes and that's something to brag about.
