on WHAT?
for incans it surely would clean up the mess that exists.
for Lux3 leds only smooth and properly MADE for that led, because there was little LOSS from the smoother reflectors, and made correctally, the beam looked great.
for these new Leds, the orange peel is a quick fix (IMO) that will allow it to work without any problems, no mater the type of led you stuff behind it. could come in handy when you change things again. also the new LED emitter patterns make things harder again for optic items.
how many lights does a good modification Resell?
Smooth whenever possible, even if the suckers have to re-tool thier whole line
besides i aint never seen a ring, when i was actually using a light for anything other than a beamshot.
