I have this idea:
Some of it has been discussed here:
but i don’t want to hijack that topic any further, so here’s the dedicated topic.
So, why a recoil set up?
It has the bigger focal distance (between LED and reflector) and it takes about ALL of the emitted light (approximately 145° in the picture above) and reflects it in parallel rays, making a very tight beam without spill (nothing is spilled basically).
I was thinking about a 4 or 5 inch / 100 or 125mm diameter reflector.
As usual a domeless LED will produce a tighter beam than one with dome, so i think an XP-L HI is the obvious choice.
I would love to see this take form and be produced, but for now we can discuss the concept.
