Is it like the sf gas pedal switch? I suppose the elzetta doesn’t fit sf/malkoff?
I just tested the hi/lo tail cap from my Elzetta Alpha on both my Malkoff MD2 and SureFire 6P, and while it technically sort of fits -- the threads match, and I can turn the light on -- it leaves several threads exposed (compromising the water resistance) and loses the hi/lo aspect; it's high only.

I know there are a couple variations of Elzetta's tail switch, but AFAIK none provides gas pedal functionality. The version I have is high when tight, low when slightly loosened (basically Malkoff, but in the tail), half-press for momentary, click for steady on. I believe there's also a no-latch version with the same hi/lo functionality, just momentary only.

Thanks for checking, and for the explanation.

Not at all. It's the same as the Malkoff hi-lo ring. Twist slightly for low, twist more for mechanical lockout. You can see the little pin sticking out in the top just like with the hi/lo ring:

Not really... I mean electronically it works, but yeah... there's like a 7mm or 1/4" gap between the body and tail shroud:

That's weird, the Bravo hi/lo tail works as expected, it gives you low as well

Thanks for the pics.

My Alpha is gen.2, not the current generation; maybe that makes a difference.
I just tried my Alpha hi/lo on the Bravo and it does not give a low as well... I think there is something fundamentally different in them, maybe the Alpha has a smaller resistor or something like that.
The Alpha hi/lo on Bravo gives only high, and Bravo hi/lo tail on the Alpha gives you ultra low moonlight and high.

Visually they seem (almost) identical:

Seems to make sense as the Alpha is one cell and Bravo is two cells. Less resistance is needed to produce a low on the Alpha and likely won’t make a (visible) difference when used with the voltage of two cells in the Bravo. The (likely) higher resistance in the Bravo tail drops the voltage of one cell to ultra low.

How does the M91T compare to a Surefire P3X Fury? The Surefire settles down around 600 lumens the M91T down around 740 lumens. SF 22k candela vs M91T 19k candela.

I have been carrying my MD3 with M91BW drop in at work the last week and have really been liking it.
Before when I had an M61W it wasn't really enough light, when mixed in with the other lighting, to effectively reach where I needed it too. So I ended up getting the M91BN. Now that thing puts out a lot of light! Especially when being ran with two 18500 batteries in the MD3.
So I decided to try the M91BW at work. It is awesome! I really like the warm tint and it has plenty of punch to get up to the tail of the airplanes. It puts out an amazing wall of light. Now I need to get another M91BW to go on the MD1.5 body I got from Fivemega.

Has there ever been any talk about making an M391W? That would be sweet.

It has been about a month since switching out my M61N’s for M91BN’s in my Hi/Lo MD-2’s. I run on unprotected 2x18350’s, but I have a few 18650’s that seem to to well too.

I think the MD2 is about as big a light as I would want. Simply a great form factor. My format of choice makes 2x123 primaries a dodgey option, but honestly, I haven’t dropped a primary cell into a flashlight in a couple years, so it is more a theoretical sacrifice.

I got my M91BN today and it packs a punch! Bigger and more intense hotspot, longer throw also. Tested on MD2 and MD4 bodies with 18650. Anyone measures the current draw on 1x18650?

Thank you, my M61N will probably be retired.

The M91 can really make you retire your M61’s. Higher output and lots of battery combinations. Although the M61 can use many different cells as well and has a bit more throw.

My experience today tells me the M91BN has more throw than M61N (SST-20). The advantages of M61N would be running on 2xCR123 with good runtime and regulation. But I find the hotspot too small and lacks throw.

Ok. wonder if the M61 SST has less throw the genes previous ones. To me the M91 is a wall of light brighter of course then the 61 but not quite as much throw.

Yes the SST-20 isn’t much a success for me, small hotspot, lacks throw and 400 lumens looks like 200.
