Hi
I don't know what style it is, but on a style that I have ....
1. Don't try to take the barrel apart. The diode was on a little pcb which
fit into a slot on the lens assembly. The pcb switch was actuated by the
button on the side of the barrel.
2. The front light exit had a removable/interchangeable "image projector".
On one unit, the beam grazed the opening on one side until I removed it.
3. I found that when I removed that piece, the lens for the diode was
actually adjustable by screwing it in and out, closer and farther from the
diode. It was hard to break loose, but once I knew it could move, it was
straightforward. The spot size became totally adjustable.
