Yeah, the cryos/m2 is deigned to take the larger lenses and rings of the Z32, but it's nearly as short as the cryos/44. It's also not larger on the inside, most of the fatness is in the fins themselves.
Z32 are made extra long and cavernous on the inside, to house all the shock absorber parts. All of these are replaced by a honking deep reflector. A finned head with this setup would look more like the size of a KT4.

Anyone had a chance to take some beam shots of this? or can tell how they compare to my old v3 triple xpg 1100L

Looking to pick up a couple of solo head...any rough ETA to keep me from checking your web site every 30mins?

Busy Busy here!
I'm hoping to get more of these built in the next couple weeks for you guys.
Thanks for you support.

If you want to lego, or use a spacer, a SINGLE CR123 primary cell will run this head for a couple dozen hours.
Whoa - back up a minute. Can I use a "spent" single CR123 primary cell with a delrin spacer and use this beast as a walking light (reduced output)? I have a bag of "spent" CR123 primary cells - I just haven't found the time to go to a proper recycling center. Do I now have a real use for them?

Yes, it will run from a SINGLE used CR123. The amount of output will vary depending on how much the cell has been depleted.
iirc this thing draws 4.2A right? even in direct drive mode, can it be fed by a single CR123?...obviously it will be at a reduced output

It is direct drive. It will draw over 4A from a fresh AW 18650 LiCo.
A SINGLE CR123 will run the light for many hours at reduced output.
initial output will be over 100 lumens.
And is there an option to send in our M2 Heads and have you LED Brain Surgeons do your thing???

Just compared this baby to my Malkoff Neutral Hound Dog XM-L2: It's a close call but the clear winner is the Oveready M2/XML2 DD! The overall output is slightly higher, the hotspot is bigger and the throw is equal. This of course in a much smaller host.
I'm extremely happy with the performance! (In the Hound Dogs defense I only ran both lights for about 15 minutes so maybe things would have changed around later?)
I ran AW 2600 in the Oveready but according to this site I might be better off with my Keeppower 3400s.

That is good to know! How do the tints compare? I would think they are real similar. I think if people realized how awesome this light was, they wouldn't be able to keep them in stock.

We can't
There's been an increasing emphasis on specifications, comparing lights, based mostly on a series of numbers (on paper). To be appreciated, the M2-50 and XML2 need to be seen, held, and used. A labor of love, we make them at the speed people discover what they have to offer - cultivating one fan at a time.
The tints are quite similar, however the Hound Dog has a slight greenish tint to the spill which the M2-XML2 doesn't have, so it wins this one too. The beamshape of the M2-XML2 is just about perfect. I hope it doesn't sound like I'm bashing the Malkoff. I love my Hound Dog and think it's an amazing light but the M2-XML2 is just better in every aspect that is of importance to me.
The M2/XML2 the perfect addition to my C2 with Torchlab Triple V4.0 Nichia 219 dropin: This light provides nice flood and high CRI but the M2/XML2 comes into its own as soon as there's a little distance involved. Furthermore its runtime is more than 2 x as long than the 20 minutes I get on high with 2 x 18350s in the Torchlab triple with very similar total outputs although obviously the triple has low and medium as well. For another level the M2/XML2 can be driven with a spacer and a single primary CR123: The output is very similar then to the low on the Malkoff and if I compare to the known levels of the HDS lights must be around 100 Lumens or slightly more (at least initially).
As I'm talking about two different lights here I'll just make clear that the M2/XML2 can not be driven with 2 Li Ions or IMRs it's SINGLE 18650 standard chemistry only or a spacer and a single PRIMARY CR123A!!!
I think you're right. I also thought direct drive was a disadvantage until now. It stays equally bright (at least perceived brightness) for a very long time and then there's this nice taper and no sudden darkness. Having said this I'd still like to see a runtime curve with this light!
i have one question though: When looking at the specs of the batteries over on this sight (http://lygte-info.dk/review/batteries2012/Common18650comparator.php) I am concerned that the Keeppower 3400 batteries calculated internal resistance (0,09 ohm) is too low! (AW IMR 2000 has 0,09 ohm as well) So is it safe to use or should I stick to AW 2600 with 0,16 ohm? Am I correct in thinking that the internal resistance is important or not? If I look at their respective discharge curves at 5 amp the Keeppower 3400 is between the AW 2600 and the AW IMR 2000 thus providing more current to the LED than the AW 2600 and less than an IMR 2000.

Nice post, good to know I don't need a neutral hound, my neutral WC is awesome though.
I have been running a RPM tail-cap (which myself, AWTYD, RPM, and a few others designed at 2008 SHOT show on a laptop CPU while drinking beers) on my M2 XML2. I see no difference to my eye in brightness comparing the zero-res and the McClicky switch. Plus it adds tail standing and it aesthetically balances out the M2 head size. What do you think?

Very nice tail-cap indeed!
On multilevel lights I like clickies (even better is two-stage like the tactical EB1) but on single level lights I greatly prefer a twisty tail-cap with upgraded performance like the zero-res in Z41. I DON'T want it to come on accidentally and love the robust reliability. Visually I quite like the M2 head on the C2 and actually prefer it to the standard head, but the I like top-heavy lights like the E1B, EB1 etc and only want tail-standing ability in lights with a very low low like the HDS.
No, you don't need a neutral Hound Dog but aren't we rather past need?
By the way what do you feed yours? Are you sticking to AW 2600s?
