Hello. I feel bad about bringing this up, but I never have any luck finding more information about these reflectors. I tried the McGizmo section of the CPF forum, but I might have posted too long of a message so my thread received no attention.
Anyways, I will soon be working on a 2D quad Luxeon III Maglite revision (an upgrade to Seoul P4s), and I need help with my choice of reflectors. I am already using the IMS SO20XA reflectors (20mm -they fit perfectly), but I am unsure if McGizmo's McR19 or McR20 are a whole lot better.
I cannot afford to pay $60+ on reflectors that I may not be happy with, so I hoped that some people here can help me out. There should be a lot of people who have had experience with these.
Now this is what I needed to know. Which reflector (the IMS 20mm or McR 19/20mm) provides the most amount of light output when used with the Seoul P4 (or any other high-flux LED really)? I need something that can output the most light in the most tightest beam. The more flux, the better. I am assuming that because the McR reflectors are aluminum and hand machined, they are better designed (with a better parabolic shape for today's Lumileds, Cree, and Seoul brand LEDs).
I was concerned how every McR reflector that I have seen has that sputtered finish on it (like orange peel). This will give you a soft beam (eww), even though the beam quality is pretty nice. I seen this thread by Nereus where he made a quad SSC P4 Maglite using the McR 20mm reflectors (still very nice). However, the beam was way too floody and soft (more than I expexted). Here is a link:

Scroll down a little and you will see the beamshot of the Quad P4 light shining down at the snow. I know that my Quad LuxIII light, using the smooth IMS 20mm reflectors, throw much better than this. Am I totally wrong? I know the larger McR27 and 38 reflectors are very nice when it comes to throw, but I am not so sure about the smaller 19mm and 20mm ones. I have seen the McR19XR version used with the XR-E, but I am not very pleased with those beams, either.
I understand that I will have to trim the IMS 20mm reflectors about 0.030" or so to properly focus them. I do not mind the little extra modification. If the trimmed IMS 20mm reflectors provide a lousy beam with the SSC P4s, please tell me. I need to know if I have to start saving for some McR 20mm reflectors. I do plan on using the preferred reflector in my future LED headlight project (once I finish my current one).
Finally, I am open to trimming and turning the nicer McR27 (maybe long or Seoul version) so they have the 20mm diameter. I am assuming that the deep part of these reflectors are what allows for the tight beam, so removing the upper part will only get rid of the less-valuable reflective surface. Too bad McGizmo does not offer smooth reflectors.
So, any help would be greatly appreciated. I understand that there is a lot to read. I felt that I could not say what I needed to say any shorter. Thank you all!
