Yes, IMS 17mm is the one for the MiniMag. You'll have to trim off the three legs for the reflector to work with the Mag switch. That is a 30 second job.

I like the beam quality of the reflector a lot more than an acrylic optic.

the beam result is kind of a tightish spot, with bright spill.

quite nice, really.

You can order them from the Sandwiche Shoppe or from one of the guys in BST that are carrying them.

They are smaller than stock, the 20 needs to be modified though to make it fit too.

I'm going to order some 20's and see if I like them better.

Can anyone tell me if a modified 20mm reflector has advantages?
Is it the size, or is the focal point that makes the difference?
How do the 17mm and 20mm compare to the refector used in the McGizmo A2 (and is that an adaptation of the Pelican M6?)

Use dremel tool enlarge inner diameter head and you will go on with 20 MM.

If you have a dremel, you can mod a so20xa to fit inside a
MM. IMHO, it's the best throw/spill compromise. Throws significantly
better than a so17xa. (plus it fills the entire head) yet
it has enough spill without the hotspot blinding you so the spill
can't be used.

Generally, the wider the reflector, the smaller the hotspot. here are
some numbers I measured with different reflectors.

Reflector / approx dia of hotspot at 1 feet
so17xa 8in
so20xa 6in
so27xa 3.5in
mag (49mm) 3in
arc4 (18.4mm) 6in

The usual cutdown of the three legs. Then the outside of the reflector
needs to be shaved down just a bit all around the mid-section (sounds
like a weight loss program) but not too much that it goes all the
way through. You'll have to try the fit, shave some more, and
repeat. The results are very satisfying. /ubbthreads/images/graemlins/grin.gif

Does the shoppe carry so20xa?

Since I want to own Apeph2 but it's high cost and use 123a battery. So I try to match Nextgen500 + TW0J + McR20 mm together. Result will come out with light pattern like Aleph2 but run in Minimag 2AA. I have version of Minimag 1AA for use with 1*AA li-ion battery. It's take a nice light too. But I don't know how to make 2 stage minimag 2AA for great Minimag for me.

A very strange dark place
Will the 20mm reflector concentrate more light (and lumens) into it's hotspot than a Fraen LP? My SX-17 will not so I still run the LP. I use my BB500 R2H minimag for a bicycle helmet light, throw is everything!

I think Fraen LP in Minimag is suit for Bikeing. Beam shape is no hotspot and will see a lot of thing on road.
