Hi all,
Just generally curious here, but is there a reflector (available via the usual sources) that could be considered one-size-fits-most, or thereabouts? Basically I'm after a reflector (>20mm in diameter) that I could use for mucking about with XP-Gs, XP-Es, Nichias and so on. Perhaps even XM-L emitters. I just don't want a collection of reflectors sitting around.
Any suggestions?

The yellow stuff causes too much tint change.
What are you on lol? Accidental post? Or am I missing something here...
If you read the subject line you’ll see I was talking about snow. White snow, in particular. I figured you’d brought some snow back with you and you could put it to good use, it’s very reflective you know! 
I’m looking for an answer. A while back there was a company that made a reflector that had steps, could be cut down to like 3 different sizes. Can’t seem to find it now though. Deree light makes a very nice reflector, you might look at their reflector lineup. Dereelight Reflectors
As you probably know, there’s not a one-sized-fits all. Too many dome sizes, footprint sizes, bezel diameters, head depth, focal length, yada yada yada. Wishful thinking on your part Matt! So, the best technical answer is a bar of 6061 in 25mm diameter.
Hope ya had fun! Back to work!
Hey - I know I had a good break because when I got to work this morning I had to get the IT help desk to reset my password because I couldn't remember it! Sorry my apologies for not being totally switched on at the moment lol.
I realized this soon after I posted, but was still hopeful. I sure as sh*t don't know everything lol. I'm only looking at this stuff because I'm thinking of having making a few single emitter drop-ins for myself. XP class emitters are nicer for throw, but an XM-L or even an MT-G light would not go astray for pure grunt.
Meh, slow and steady.
Turn your own. If you’re only looking at making a few or a couple of specialized light for yourself it’s the only way to get exactly what you want. Not the easy way, but perhaps the best way.
Phoenix electroforms makes various reflectors, but they’re very expensive. Phoenix

Lots of beamshots with both XML & XPG in that reflector here: https://budgetlightforum.com/t/-/20093?page=1#comment-445402
I've cut 1/4" off the front to shorten them enough to fit in stumpy-reflector lights like TR-801 and they still work nice. The hole is XPG size, but an XML dome fits fine, and the base is stepped so it will locate onto an XML centering ring/insulator.
Thanks for the link. It looks like it might work, though I guess I should compromise a bit. I need to look for reflectors specific to XP-G and XM-L emitters, but that have the same external dimensions. Should be able to find something.
That one works good with both LEDs as-is. If you want, the hole can be bored out to XML size (there's a step in the base that gives an easy guide to cut to) without screwing up the beam pattern at all. In fact the Convoy S2 comes with that exact reflector with the hole bored out just like that. It doesn't have to be cut to work with the XML, though.
Sorry if I'm being pedantic here over such a cheap part, but you say "If you want, the hole can be bored out to XML size" but then say "It doesn't have to be cut to work with the XML, though."
If it does not need to be cut to work with the XML, then why do it all? Is this just so that the LED sits further into the reflector? That's all I can think of. Still, thanks again for the link. I think this is the one for me :)
Because people are weird, and some people would never understand that an XML will 'work' in a reflector with a 5mm hole. 'XML reflectors have a 7mm hole, XPG must have a 5mm hole, anyone who says otherwise is just being silly.' or 'that's not an XML reflector, it only has a 5mm hole!' Know what I mean?
It can be cut if you wish (if you're one of 'those people'), and doing so doesn't cause artifacts or other weirdness with the beam. Leaving it as-is works, too.
Sounds good to me :) You don't happen to have one on hand do you? Can you confirm the external dimensions are 20.5mm by 20mm? I'm getting confused by the 'depth' and 'width' measurements on the Fasttech listing. It's not important - I'm just doing some drawings and it will be a few weeks before my samples arrive.
.805"[20.4mm] OD, .792"[20.1mm] tall. There's a ring or lip around the base, .042"[~1mm] taller than the surface that sits on the insulator. So if that lip is trimmed off, the height from the front face to the base is .750"[19mm].
Inside surface dimensions are .750"[19mm] wide at the front, .732"[18.6mm] deep.
Thought I replied to this already....it appears not. All I said was "Thanks!".
So um, thanks!
