In the USA the first version of this light was the Stealthlite 2020 or something like that. It had a great beam that was almost square like the die of the LED itself. Scatter was almost nothing at all. The only flahslight I have with a beam nearly as tight is a Maxabeam.

The one I had had a screw to operate switch and was total garbage. They changed the materials used, but it was still poor. It was hard to turn on and off, or would turn on an off itself. There was never a clear separation between on and off either.

Pelican needs to come up with a better switch system. Toggles that don't lock on or off without a peg that breaks off is stupid.

IIRC the military uses some LED flashlights with the LED mounted

gets less backscatter in a dusty environment.

That might be the Pelican Recoil.

Similar idea, but this requires a fairly large reflector so the 3/8"
dia body of the LED and its support structure don't present
significant obscuration.

I believe Ian Stirling is/was contemplating this configuration using a
sapphire lens as both support and heatsink.
