korpzgrinda did it and mentioned here (not the 18350, but the 18350 S2+ Desert tan 4*7135)
I ordered one with these specs, from Simon:
- SMO reflector (that I may exchange for a pebbled TIR lens)
- XPL-HI U6-4C led
- Biscotti with 3*7135 chips (that I may turn into 2*7135, or not)
- Forward tail switch (well, to avoid the “clicking” noise during the night)
It is on its way. I don’t have another S2+ with biscotti on 4*7135 chips, but I have a modded light with these specs: 4*7135, XML2 U6-3B and pebbled TIR lens.
The 0.1% mode is low, but not low low. I expect the 3*7135 to be a bit lower, but I don’t have it yet to make comparisons. In some weeks I can show some pics, when it arrives.
The pebbled lens helps to smooth and diffuse the beam, and reduces the visible output a little bit, but it is not a “true” moonlight, for what I can tell.
Here is a comparison with that modded light I mentioned with some other lights, all on lowest settings: Convoy S2+ mode selection question/problem - #17 by MascaratumB
Hope this helps
