Man, you really love coast lights, and the zoom lol. Not understanding the obsession honestly.
It’s a triple Carlco optic. There is no zoom. It sits right against the LEDs, and creates a uniform beam much nicer than the one that the original optics created with the XP-E LED. I put it up to an XM-L and it still looked bad to me, so I much prefer the triple. Was never planning on using the zoom lens in the first place.
