I had no previous experience either. It turns out that glass is fairly soft so no issues with cracking or chipping.
My main concern was (as is) to wear a mask and to use the grinder where you can clean up the area easily. Keep the area around it clear so that powered glass dust don’t get on things.

i got four from surplus shed awhile back. every thing that was close in diameter and focal length, none were a drop in. needed extensive work to lens or housing. will post part numbers that didn’t work if you like.
Just the same diameter as the reflector of the C8. I tried with a cheap 30mm convex plastic from another light and the result was not so bad but hardly brighter.
The new XML-2 LED pattern make it way better for aspheric.
I bought the aspheric zooming C8 host from Wallbuys a little while ago. I put a de-domed XP-G2 1A in it. Very tight beam and throws pretty well but the optic isn’t very good quality so I didn’t do anything more with it.
The problem isn’t the shape of the aspheric lens, it’s the reflector. You need a special reflector to focus the beam to a point behind an aspheric lens. The light that gets straightened by a normal reflector is already being focused straight ahead and adding an aspheric lens will only bend it in unwanted directions.
I received my aspheric glass lens ! The good news is that it is of good quality and a perfect fit in lieu of the standard C8 glass, the bad new is that it is too far away from the led and so it is not focus at all so its useless… Cant even fit deeper in the C8 since the edges become narrower.
The lens in my aspheric zooming c8 is very thin compared to yours by the looks of it. Mine would only be ~10mm thick at most.
I tried the lens out of my UF-T20 Host once as it is a perfect fit and the light was utterly useless. The emitter needs to be much closer to the lens when they are that thick.
Sorry for the late reply I have forgot about this…
The beam is full of rings & artefacts and I have WAY less lumens than stock reflector. Totally useless.
Its WAY too far away from the LED, playing with the pill screw does absolutely nothing.
Well… I understand nothing about your thread… You don’t specify the lens and where you bought this C8 model, nor pictures. But you say on this thread this a lightmall C8, but where do you get the lens ? It was perfectly at the right heigh in-place of the regular glass ?
I have never mentioned anything about a lightmall C8? The only other post I have made was on the previous page stating that I bought the Zooming C8 host from WALLBUYS and then linked to my build thread for it. I never bought another lens, it came with the aspheric and I did try the thicker aspheric out of my UF-T20 and it didn’t work.
