Do you think this is the same optic Wuben and FireFlies used in their quads? If so I would liken it to something between narrow and medium beam width and lightly frosted in “Carclo” terms. It’s pretty good if you are not looking for overly throwy or overly floody.
Edit (stolen from Wuben thread, thanks Chatika vas Paus):
Yeah the Wuben/Fireflies quad optic is much wider than a Carclo triple.
The KD triple optics I have are very throwy, and have almost a clear, “empty” looking spot right in the center of each individual optic. You can clearly see the emitter with no distortion/magnification I can see through the center. They don’t seem as efficient Carclo ones though, but that could be the light going into the wider spill vs Carclo narrow spot maybe? Hard to tell by the naked eye.
