Here are part of my test results:
-----------------------------------------------------------------------------------------------------------------------
The flashlight appears to be very durable and sturdy, and it is. Ordinary flashlight accidents should not be enough to do it in. I administered the smack test on it (ten whacks against the corner of a concrete stair; five whacks against the side of the tailcap and five whacks against the side of the bezel), and found absolutely NO damage. No optical or electrical malfunctions were detected either.
I also performed the "drop test" as it was asked of me to do so. I dropped the Arc-P ten times on a concrete sidewalk (two times from pocket height when it was on and three times when it was off; and two times from chest height when it was on and three times when it was off) and found only some very, very, VERY minor damage to the end of the bezel from when it struck the sidewalk face-first; no optical or electrical malfunctions were detected.
It has a Type III hard anodized ("HA-III") finish on it, so it should stay new-looking even if it goes up against keys, coins, or other flashlights in your pocket or on your keychain.
The Arc-P is water-resistant AND waterproof too. When I dropped it face-first in a large (16oz) glass of water and left it there for one minute, dried it off with a paper towel, and opened it, no water was found inside, and it still functioned properly.
Another one of the experiments I was asked to perform as part of beta testing was the "cold" "hot" test, to determine if the rivet in the bottom of the Arc-P's battery holder would wiggle loose.
For the "cold" part of this test, I placed the flashlight in the freezer at -6°F (-21.1°C) and allowed it to cool for one hour. This is the lowest temperature I can obtain, even though the Arc-P should be reliable to -40°F (-40°C). I then attempted several battery changes on the cold flashlight, and turned it on and off several times.
The "hot" part of this test was done by heating a coffee cup of water in the microwave oven to 147°F (63.9°C), placing the Arc-P in the hot water for enough time to allow it to heat (approximately one minute), then attempting several battery changes on the hot flashlight; paying special attention to that rivet at the bottom of the barrel. The maximum temperature specified is 150°F (65.6°C).
In both parts of this test, the rivet did not loosen that I can detect, and I performed several battery changes while the Arc-P was cold and while it was hot. And at least once during each part of this test, I held the barrel vertically (straight up and down), inserted the battery in the barrel, and allowed it to slam to the bottom. I also turned the flashlight on and off a number of times. So I believe it passed this test.
I turned the Arc-P on and off 1,200 times (both on and off, so 2,400 twists of the bezel) in about ten minutes, and no failures or malfunctions were detected. I realise that real-life cycling is far, far, FAR more than 2,400 twists, but my hands were pooping out, so I stopped at 2,400 twists.
This test was conducted over several hours, not all at once. /ubbthreads/images/graemlins/jpshakehead.gif /ubbthreads/images/graemlins/wink.gif
