Does this light exist? All the "zooming" aspheric designs I see are very small diameter. Are there any big ones?
The Lenser X21 is a 'big' zoomie.
>>>>Big price, 7 small lenses, however.
I just think there are far too many compromises versus a reflectored design, and the significant cost of a good lens only compounds the problem.
small sun c10s is as big as they get, in the budget class, afaik.
the tractor supply 3xD zoomie (no longer available) has a ~50mm lens, with great results (w/ emitter/driver/heatsink mod).
From my experimentation (and for my purposes), if you go bigger, it might as well be a dedicated thrower.
I'm (slowly) working on one, because the lack of spill is useful when boating in inclement weather.
