Let me tell you about this flashlight and the various models. First, you would imagine it was a tough Aluminum, and yes, it would be strong. But imagine the shell being at least 1/3 thinner, and made from Titanium! Naturally, HA3.
All the models you can imagine from single cell EDC, up to CR123's, AAA, AA, C, and D models. Variable brightness via a rocker switch. Again, made from Titanium!
The modular design lets you swap caps and lens easily from stock parts. EDC models emit a true 60 lumen's or more. Larger models emit 120, 240, and 360 lumen's. The 360 model uses multi 5w Luxeon LED's.
Swap out the 1.5v batteries with those 3.v models, it's OK, it was made to withstand the voltage.
It has a twisty head to go from an absolute throw, to a "spot light" like wide beam.
Oh, and did I tell you no such flashlight exists?
At least not that I know of. Scotty, beam me up. They are getting restless.
<ducks from stones and spears>
Now imagine the Fenix L0P or L1P. Two of the best EDC's in the world, right? Well, not until they thin them up with titanium, and allow those 3.0v batteries in rechargeable form. Heck, with Titanium, probably could make the shell half as thick. Dang, who WOULDN'T buy one of those?
