I separated from the US Navy last year after serving for 8-1/2 years. The last 6 years were on the ballistic missile submarine USS Nevada. Flashlights are an absolute necessity on a submarine. You never know when the lights will go out, or when you'll be crawling into the bilges to fish out a vital nut or bolt that you dropped while repairing some equipment.
I tried many different flashlights, from cheap 4-pack ones from hardware store checkout lines to the expensive $400 tactical lights. I eventually picked up a LED Lenser P5 and gave it a shot.
For 3 years, I carried it in my pocket, often using it for several hours a day. It has been dropped from several stories onto concrete & steel floors. I have dropped it into bilges full of oil and saltwater (and been unable to find it for hours). It has been used as a door stop, a hammer, a pry bar, and occasionally a drumstick (hey, mid-watches get boring, okay?).
Now that I am out of the Navy, I still carry the SAME P5 to work every day. I now repair industrial robots all over the country, and spend plenty of time in factories and foundries and other nasty environments.
This little flashlight has NEVER let me down, and it has taken more than its fair share of licks and kicks! Thank you for building a flashlight that can stand up to a life of hard work! Best of all, it only needs one AA battery, but it's still bright enough to be used as a tactical light!
