Speaking of prototypes, one day a DHL truck unexpectedly stopped at my house and dropped off a box with a return address written in Asian characters. "What in the world?" I thought.
I was walking on sunshine for days.
A titanium Paladin, PK Warrior 1 by Powertac, a PK-1 by Fox Fury, a cerekoted FL2, the executive pen, another pen that never became a production item and a PRX with a smooth reflector. All prototypes. The FL2 was one of two that color with a yellow and a gray somewhere on planet earth. The PRX was the first prototype with a smooth reflector.
Check out the S/N on the Warrior 1
Another day another box arrived.
The first PRX off the assembly line.
Shown with it is the only PRX prototype with orange peel reflector. At that point PK had
only squeezed 450 lumens from the LED, but had surpassed his old record of 430 with those Paladins and Knights. Final production items are 550 lumens from an ordinary primary.
