As djozz mentioned, you don't need to modify reflector in any way for Luxeon Vs.
Oh yeah sorry. I actually meant the centering discs.
Just found that out. 
I have an XHP70.2 centering ring that was 3D printed using glow in the dark material. Would be nice if someone could organize a batch of these (with the fit the Luxeon V needs) at a reasonable cost. Green GID would work well with the already green lighted switch.
Low quality picture of what I mean, Convoy M1 with XHP70.2 centering ring and reflector reamed to fit.
lol, I have been trying to keep this quite for awhile. I have actually been planning on using this idea as a branding trademark for my lights for almost a year now. Just got to get some lights made first.
The one I have is a bit “rough” and needed a little bit more slicing with a knife to fit properly but it does glow decently for a short period after the light turns off. I suspect going even smaller than XHP70 size accuracy gets even worse though. Is it a printer issue or just the nature of this material? IDK.
The other popular way people implement these is under the 3Up and 4Up optics but almost all my lights are incompatible without modifying it. Jaxman E2L triples have that shelf that prevents the glow ring from going down to the MCPCB without trimming it. My S2+ triple uses LED4Power’s MOSX pcb so it has a FET and other stuff on the PCB so it wont work there either. I dont have a quad version but im afraid a D4 might melt or deform one of these suckers but people claim it doesnt…
I’ve printed my XHP70.2 centering ring for the BLF GT, but I don’t think I can print a centering ring for the luxeons, they’re so small and tolerances are big
I figured as much. Is that universal to all printers with this material?
I have printed many many many XP 3535 LED centering rings over the years. It takes some time to get the settings right but it works well.
Well by all means let me TA up my Q8 and C8F with some new rings, lol. What are you waiting for :money_mouth_face:
LOL, I actually posted a thread offering custom centering rings awhile back and got exactly zero response to it so honestly I just figure it was not something anyone needed.
E2L is easy you just run glow tape around the outer edge under the optic.
If I had a 3D printer I would have 100% made my centering rings for my Q8. I can get a friend to make stuff, but I’d need trial and error to tune the rings correctly and he’s not close enough for that.
This Luxeon V mod may just generate a big demand for custom centering rings, not everyone may have the patience for this finicky time-consuming reaming job. 
If only you were as good at marketing as you are at modding!
Eh, I can market pretty good when I want to. I just don’t like marketing to friends, so I don’t try very hard on BLF. I also have never really gone for the pushy marketing thing. I prefer to sell things that are obviously superior and let them sell themselves.
That is possible. I have one incoming for myself. Once I get a centering ring made for mine I will most likely offer them for sale as well.
Please do, I will need 6 sets for Q8’s as soon as you are ready. :laughing:

BlueSword, djozz, led4power, thanks for all the answers!
BlusSword, thanks for the link to djozz’s test thread, I found these posts there that provided positive answers for my concerns about the tint compared to Cree:
.
Hopefully TA and/or led4power will offer the proper centering rings soon.
For lights that have an XM-L size reflector opening would it be best to use these (slightly reamed out): XM-L Reflector to XP-G Converter rings ?
These also appear to be “converter” rings as they fit a 5mm reflector opening: http://www.kaidomain.com/p/S024679.15_6mm-L-x-9_5mm-W-x-0_9mm-T-White-Plastic-Insulation-Gaskets-for-Cree-XP-L-5-pcs
.
If the rings have a square hole should I ream it out to a circle, or file the inside edges to keep it square?
.
I also found these donut style rings with 4.5mm inner hole (not sure what LED’s are 4.5mm?)
Would these work? But I have no idea what size reflector opening they fit.
