It seems I fail badly at speaking clearly today. This is not the only discussion where it shows…
I was debating 2 cases:
- theoretical advantage of multi-emitter throwers (the sole advantage being smaller head volume for the given throw)
- getting more lumens out of LEP lights to make the beam wider
On the first topic I meant only diameter increase that would keep reflector area constant.
On the second one I meant to keep head size constant by having more emitters and smaller per-emitter optics. The purpose would be to have the advantage of superb throw that LEP offers while widening the beam (so I can see the target without binoculars). Though I mentioned a larger head because of thermals - this would again narrow the beam down. So keeping the as-much-throw-as-size-allows that LEP offers together with beam that’s wide enough for me doesn’t seem possible with W10 tech. I suppose that to widen the beam one would have to either reduce thermal issues by underdriving the LEP or by purposefully defocusing the optics. At that point indeed LEDs look more attractive.
But you mentioned another topic that I haven’t seen before - “crystal”. Quick search - you mean single-crystal phosphors, right? I wonder what’s the source of your price quote, I see some company claiming them to be as cost-effective as mixed phosphors.
Do you know of anyone who tried transplanting such phosphor on a LED emitter? Seems like something that saabluster would do.
