I can report that the M61LL is significantly dimmer on 2x NiCd than 2x alkaline AAs
Surefire 9P + 2 x Eneloops + M61WLL (Yes, I already searched!)

Its amazing to me that such a small difference in voltage on the Malkoffs can make that much of a difference . I wonder why that is? I read that they stay in regulation down to 3.4volts? but I see a difference at 4.8 or 1x18650 at 4.20 off the charger.

Please stock more neutral LLL's please!!!

Test one complete. Lap 1 is fully regulated. Lap 2 is dimming.
Cool Dan - but just so I am clear - is this with an M61WLL or an M61WLLL ?
Thanks again for doing this!

Sorry, that's a 61NLLL in a G3 with 3x SF 2021 cells testing fresh on a ZTS and volt meter.
On it.
On it.

so does that mean you have 1 more M61NLLL in stock? or are you keeping that one? 
also, is the LLL brighter on 3x CR123?

Why on earth is no one stating what LUMENS they are getting with these setups?
ceiling bounce, close to, almost, seems like.....SOMETHING. By the way, I will be getting a M60LL for my Surefire Lego Project: M2(old style) Bezel, 9P body and a Z41 tail cap with a McClicky installed. Nice to know I can run it with 2 AAs If I have to.

Can't really see with the eye but the light meter is reading 25% more on 3 than 2.

PM sent.
Overready had some in various flavors ysterday PM and still showed several in stock after my two.
O.K. so the runtime with the M61LLL on 3 Cr123a batteries runs longer than 2 Cr123as and the M60LL runtime is longer on 2 Cr123as than 3 Cr123as. Do I have this correct?
How does the M61WLL react with 2 or 3 Cr123as? Longer runtime with 2 or 3?
Hope its O.K. to ask about Cr123a instead of the OP's 2 AA question.

I tried running to alkaline AA's in my 9P yesterday. They were low to start (1.04v each). I used an XR-E 3 mode low voltage (.8-4.2v) LED. It provided a nice low light, and it looked like it was a little brighter than moonlight mode for over an hour or so (maybe 1-5 lumens). The light finally ran out. I did not untwist the switch when the light went out. A while later, I checked the light, and noticed that my rubber boot on the switch looked a balloon (about half the size of a golf ball and very squishy). I immediately untwisted the switch, and the air deflated from inside the host from the switch. What gives here? Do the batteries create air pressure inside the host? Was it a gas from the batteries? I checked the batteries when I unscrewed everything, and they both read .48v with my DMM. No heat was present. No leakage of batteries. Any insight on this? Did I damage the rubber boot on the switch? I tried this again today with more AA's, and the light and LED still work.
Will this rubber boot/switch issue happen if I use a Malkoff M31WLL also?

I avoid alkalines like the plague - I would assume you had some sort of "venting" going on there. Anything's possible with alkaline.

When an alkie peters out it's important to remove it ASAP.

OK Thanks. It was just weird. It caught me off guard.

Can't believe I volunteered for this
M61NLLL on 2 Eneloop 1500x AA's (blue). Passing hour 94, its now dim enough to look directly into the LED.
So 24 hours of good output, followed by another ~70 hours, g r a d u a l l y declining from there.

We all need one to fall back on!
Special thanks to the guys at Oveready for getting those N tints made!
My favorite.

Well I noticed the boot "balooning" pretty much with any soft boot installed on high quality tailcap (triad or Z41) as all o-rings are good and well lubricated, so once I screw tailcap all the way down (McClicky installation), the rubber goes slightly baloony... If it was more than before, then it has to be batteries and it's never good idea to keep emptied batteries inside so well fitted host, be it either alkalines or lithiums... The only thing I like about alkalines is that should not be able to start the fire like lithiums used to be infamous for... Maybe I'm wrong, like I stated in another post, I'm just more relaxed knowing I have alkalines in the hot vehicle... All my other flashlights are Lithium based...
9P with M31WLL is a sweet setup for situations where alkalines are much cheaper and easier to get...

Wow! Very impressive. Thank you for taking the time and effort to do this for us. :thumbsup:
