I run a M91 in a bored out 3 cell Surefire body, excellent light. You should be able to fit 2x 17500 li-ion batteries in your Z3 for guilt free lumens :)

Other high end options come from TorchLAB, in the form of their triples. Cool XP-G2, neutral XP-G2, or Nichia 219 are offered. Choose between single mode, low medium high, or high medium low.

The hardest part is finding what is wanted in stock.

Having said that, the Malkoff M91AW is an awesome choice.

Lots and lots of options, especially if not limited by price :)

My personal choice would also be the Malkoff M91.

If you wanted totally custom ... vinhnguyen54 can build to your exact specifications.

If you are using primaries, either M61x or M91x will serve you well. For li-ions, the 2*17500 will power M61x or M91x without any problem, but the 3*16340 can only run M91x due to higher voltage.
If you are using AA batteries, buy M31x and enjoy it with either 2*AA, 2*Eneloop, or 2*lithium AA.
Just that for now, and :welcome:

Here are a couple more very nice neutral options that enjoy high voltage:

Malkoff M61N SHO and M61 SHO 219

I don't use mine nearly often enough. :)

I've had good luck with Nailbender, Lumens Factory, Solarforce, and Malkoff units. I've become a tint snob, so my personal favorites are Malkoff M61N (neutral tint) or Nailbender neutral tint units.

You've got a great starting point. The Z3 is one of my favorite designs. I sold mine awhile back. Open head, take out P90, drop in the LED module, screw head back on. You may want to remove outer spring of the LED unit (negative contact that makes contact with flashlight body when closed) if the head doesn't close.

2 of the 17500 lithium-ion cells will perfectly replace the 3 CR123's.

In the 3-cell body you can also use a single-cell spacer and a 16650 or 17670 battery that are the same length as 2 CR123's. Might not be enought voltage for the M91 though. I ran a Malkoff M61 with a spacer and a 17670 in my Z3. I currently have a Nailbender XPG2 drop-in and a 17670 battery in my 6P.

(edit: just realized I already posted in this thread right before yours years ago! Lol!)

The preferred unit will depend greatly on how the light is used. The single mode is best if it'll be used in a tactical role...one output, with no possibility to accidentally activate the wrong (or the REALLY wrong) mode. The multi-mode option would be best if the light will be used in a general around the home role.

I personally consider high output (SHO and M91) Malkoffs best suited to hosts that allow for a low output mode, like Malkoff and Elzetta.

Okay. The malkoff arrived. Interesting tint. Ots orange like an incandescent. Not as bright as expected but it is perfect for use in a house or yard. It literally throws it being that lights up the entire room

That M91 does seem to be really lighting up the entire room - the P90 is only satisfactorily illuminating one small spot. :)
An M91 is a 'floody' design; they never do look quite as impressive as the one small bright 'spot' of a thrower - but is far more useful for most applications.

-----

A bit of history for context:

When Malkoff went from the M60 to the M61/91 models, one revised component was the new reflector design.

The newer series has considerably more flood; many (including me) has found these much more useful for general use - this of course reduces the 'spot' intensity (i.e. maximum lux).

The 61/91's do not have quite the reputation of the 60's (or other larger-reflectored dropins) for 'throw', and did receive some small initial criticism in this specific aspect before getting general market acceptance as being a substantial improvement over the 60-design.

-----

Edit: The way I have looked at it:

  • My prior car flashlight contained the M60LL; an adequate hotspot with very little spill. Fantastic runtime.
  • I replaced that dropin with a higher-output M61L; a comparable hotspot to the M60LL but with much more spill - far more useful IMO. All of the increase in output of the new single-L went into the spill, not the hotspot; with a modest loss of runtime.

Edit #2: A comparison to the P90 that you're doing is a bit of a tough one: the P90 incan lamp assembly was a pretty epic bulb for its time - on fresh cells, it will have nearly double its listed output, IIRC. :)

I completely agree with your thoughts on the flood vs. Spot. It is amazing that it can light up the entire room and still through a blinding spot
