head mdc cr123 with 2AA host = ok
because each AA is 1.5v
2x 1.5v = 3v

head mdc cr123 with 1x 16340 or 1x 16650 or 1x 14500 or 1x 18650 = NOT ok
1x 16340 or 16650 or 14500 or 1z 18650 is 3,7v

Yeah, I am getting it now. The issue I was having is the Malkoff website is all over the place. They really need a better naming convention. Like MDC-A for 0.8 - 1.7 volts, MDC-B for 2 - 3.2 volts, etc.

Anyhow, just got off the line with them and all is good.

Thanks!

Bump for old/new MDC1aa
The guy that started this thread sold me the 1-2v neutral MDC head with a stainless bezel ring a few years back. I swapped it to a Klarus P1a at times but recently decided to give it its own body. Glad I did.

Now, was there ever a time these started on or about 3.0 lumens, not 0.3? I ask because

Left is a gen 2 Elzetta Alpha on 7 lumen low.
Right is the MDC 1aa on low/low.

Actually I kinda like the way Gene programmed it to change output based on the "on time". I use that as a memory feature to get it to start on the middle output. (I call it medium but the official name is low.) So when I'm done with it, I turn it off and half press quickly to get it to start on medium later. Eh, it takes practice but it's easy enough. Plus it allows for morse code with practice.

I may take the clip off and use the holes to thread a wrist strap through it but that could lead to a water intrustion point.

OP here! Can't believe it was 2016 when I decided to put on my big boy pants and finally get me a Malkoff! I remember the day I got my first one. It was a roughed up user that I bought from a forum member and I was so excited that I drove home on my lunch break to fish it out of the mailbox. I remember distinctly that the smooth black anodizing reminded me of a bowling ball (lol) and I was blown away by the sub lumen low. Had never seen that before! I would literally throw it on the ground to show my wife and kids how tough it was, and later decked it out with a steel bezel ring. Ah the good old days. Well, I think I'd like to revisit those days, so I'm on the hunt to rebuild that light. I had a bead on the old style body, but dropped the ball so now going to search again. This was before the neutrals came out, never mind the Nichia models! Oh another fun fact, I believe that I was the only person that sweet talked Gene into building a AA MDC with a warm emitter. Ended up selling that one to Infrnl while he was doing his famous Malkoff Runtime Testing. Anyways, just a little rambling and I'll update as I get my old light pieced back together. Feel free to post your photos and loving thoughts about this classic badass light!

I loved the "big boy pants" part, because I felt exactly the same way.

I remember, years back, thinking, "Why in god's name would a single AA flashlight be over $100? How does that make sense?" But, it was made in the US, and I wanted an AA light made in the US.
The second I pulled it out of the packaging from the mail, I remember just gasping, "Whoa." It was clearly a real tool. The anodizing was beautiful. It was hefty, but not heavy, the threads felt like butter, and the beam was great.

To this day, my MDC AA neutral is my favorite light. Perfect mode spacing, and I must have won the tint lottery, because it's the most gorgeous yellowy beam of any SST-20 I've seen (I very much like the high CRI SST-20).

Fast forward, and Malkoff is the primary brand I buy. I even picked up one of those Nichia 519A MDC's this year. I'd enthusiastically recommend picking up either the SST-20 neutral MDC AA, or one of the 519A ones. They're both great.

And, while the new body doesn't LOOK ergonomic, it's absolutely amazing in the hand. The smooth portion has this nice taper RIGHT at the balance point, so it just perches between the fingers perfectly. I always used an icepick grip on my rear switch lights, but this is the first one that isn't a pen light I enjoy using in a cigar grip. It's really, really good.

So you have the current 50/50 ribbed/smooth barrel version?
Mine is ribbed throughout.
I asked Gene if there was ever a 3.0 lo/lo version and he said there were a few versions over the years and starting on 3.0 was one version.

I agree about the neutral tint. I've always like his neutral tints. Bright like a cool beam without the harshness.

Yeah, I have two MDC AA's, so one is the fully ribbed one ("the doughtnuts"), and the second (newer) one is ribbed about half way.

The new, current body is fantastic in the hand:
 
Malkoff virgin here. Is the AA MDC the best entry point to the MDC world?
Depends on what you're looking for. That's where I started (MDC AA in neutral), and I haven't stopped, haha.

Kosen still has the 519A MDC AA in 4500K :

The AA isn't as "Lego" as the MD ones, but it's a really great all-around light for use indoors.

I'm also loving the single CR123 body (running a 16340) with an M61WLL in a VME head. That's a great single mode light for around the house.

Then again, and MD2 with an M61NL or M61WL with a high/low ring is also hard to beat. Not the brightest, but two good modes and loooong runtimes. I prefer the tricap.

The MD3 with an M91BN, body extender kit, and tricap with two 18500's is a really stunner; pretty and powerful.

The funny part is Malkoffs are MUCH brighter than the specs would suggest. My neutral Wildcat is "900 lumens," and I have an Acebeam E75 that is 3000 lumens (with the 519 emitters), and I can't really tell a difference in the brightness, but the Wildcat doesn't have the stepdowns of the Acebeam.

I started with a lot of M61's with a High/Low ring, but not mostly prefer the M61NL or M61WL.

DOH! Looks like they are sold out. Hard (at least for the first one) to justify the 66% increase over the Malkoff (taking into consideration the 20% first time buyer discount). BUT - I don't know what I'm missing in the Nichia, and I've done this with other things (knives, as an example), and later eaten my words (I have a few Chris Reeve knives....)

This sentence alone is *extremely* helpful. My indoor needs/uses for flashlights is pretty minimal, and probably already covered with the handful of other SkyLumen lights that are not getting much use. My primary considerations for my next FLs are probably narrowed down to (1) cars, and (2) outdoors.

For the cars, I keep a SOG DE-02 in one, and am going to put my SureFire 6PX Pro in my wife's, but I could see the need for something bigger (at least in my car).

For outdoors, I use a Zebra headlamp and SkyLumen XVIII in outdoor situations, and both always need to be recharged after every use. Maybe something with longer run times would be good.

Much of the above is Greek to me, so I need to do some more homework to be able to understand (and respond).

Same comment as above, but I'm starting to understand. I think.

My best guess is that I will start small - mainly because the smaller the FL, the more likely I will have it with me. And based on that criteria, it seems like the MDC HA 1CR123, or the Kosen VME, would be the place to start (and notwithstanding the higher cost for the latter). Or maybe the Kosen Bodyguard.

Yes, I'm all over the place.
 
The bodyguard is a short term turbo blind the perp trying to kill the Senator or other person being guarded then drop down to a useful output to see the results of the damage caused by said body guard.

An MDC 123 body can use a VME head with an M361, M61 or M31 or an MDC head.

MDC AA is limited to a point due to the AA battery itself and the lack of options.
 
I think the MDC AA is the most practical with using common batteries or eneloop rechargeable while the output levels are perfect. If I could only have one Malkoff, AA would be it, plus the AA body fits perfectly in hand where the CR123 body isn't as ergonomic

Then you can always get a li-ion MDC or VME head with li-ion drop ins and then have the option to use 14500 li-ions. You'll get better runtimes using 14500 than 16340, especially on high output. Many M drop ins will also run on a fixed lower single output while running a common 1.5v AA which is a nice hidden feature

I have both the SST-20 Neutral MDC AA and then the Kosen with the 519A. Side-by-side, against a wall, the 519A looks so much better. In use? I actually prefer the softer hotspot and yellow tint of the SST-20. 66% more expensive than the SST-20 neutral IS hard to swallow, especially cause I find the SST-20 neutral to be so good.

Where Kosen is MORE interesting is that you can buy a ready-to-go AA body with a Li-ion head. The 3500K 519A looks fantastic, AND that version comes ready to use a 14500 (doing so from Malkoff requires buying an appropriate head and then an AA body separately). It won't really run on a single Eneloop is the trade-off, along withOUT the PERFECT mode spacing of the AA.


Bykfixer explained the Bodyguard well. Personally, I think the Elzetta Alpha is a better execution of that concept (with a Thyrm).

Honestly, if you're looking for an outdoor light, try the M91BN. It's an amazing drop-in. You'll probably want either an MD3 Tricap body with an extender kit to run two 18500's, OR you'll want an MD4 body to run two 18650s. Use the High/low ring, and you're golden.

The MD2 M61 setups (I only like N or W because I hate cool white) are nice. You can run a single 18650, or two 16340s for a higher voltage (higher low with the high/low ring). The M61HOT isn't a bad option with an 18650 in an MD2 body.

The 21700 body is...interesting. I'm NOT on the 21700 bandwagon (despite my giant meat mittens). The 21700 body requires removing the tailcap to replace the cell (opposite of all Malkoffs), but it DOES still run the High/Low ring. That with a L or LL gives you an insane run time.

Malkoffs are designed for CR123A batteries, so they do NOT have low voltage protection, so use protected cells (Illumn sells most of the Keeppower cells you'd want).

Also, if you get an MD body, just order it with the tailcap, and you save some money. If you do the MD2 body, you can usually get that WITH the head AND the tailcap for a very nice price.


Step 1: Do you want to use P60 dropins and/or a high/low ring, or do you want to use e-series bodies with single piece heads?

I have WAY more fun with the P60 ecosystem, but some people are really into the e-series world (I find that more expensive).
The e-series option tends to allow for smaller lights, but Malkoffs are about reliability, so they're not going to be the smallest.

Oh, and a pro-tip that took me a bit of time (since this Surefire ecosystem is long since discontinued):
P3 = 1 CR123 -> M31 Malkoffs (<3v)
P6 = 2 CR123 -> M61 Malkoffs (~3.4-9v)
P9 = 3 CR123 -> M91 Malkoffs (~5.5-12v)

M61's are cool, because they run on one Li-ion cell, or two.


If you REALLY want to go down a fun rabbit hole, a member here (who unfortunately passed) had a great YouTube channel, and his MD3 omnivore video was just so eye-opening for me:



I was actually reading posts here about this about the time I found the videos, and didn't realize it was the same guy, haha. Unfortunately, it's harder to do this these days, asthe Overready sleeves are long since out of stock (the 17mm one works well enough), and the M31 219B options through Illumn are mostly out of stock (I did the M31L with a high/low in an MD3, and it's AWESOME on two eneloops).

Also, search the forum for the thread, "Malkoff Runtime Graphs - CR123/Alkaline Comparo" by INFRNL and bookmark it. That's going to really help you understand a lot of what options you have in the P60 world.


The more you can really describe your use case, and what you are looking to do with it, the better suggestions we can all make. I'm sure, between everyone in this thread, you can get opinions on every single Malkoff product ever made, hahah.
 
First, thank you all for your replies. And I'm sorry to the OP for derailing this thread. I did post another thread with a bit more info, including some of my use case (https://www.candlepowerforums.com/t...e-zl-streamlight-and-skylumen-malkoff.486239/), but I think it's in the wrong forum, and I can't quite figure out how to delete the entire thread to repost elsewhere.

Second, I will read through this when I have a bit more time, with the hopes that I can figure out and understand the terminology a bit better before asking more questions.

I agree 100%. The MDC AA was my first Malkoff, and if I could only have one, this would be it.
Thank you.

As for my use case - I should admit up front that I don't need anything, as most of the flashlights I already have are not being used (or even staged for use). But I'm open (and trying with one of the SkyLumens) to pare down to items I will be more likely to use, or at least get more enjoyment out of using.

So - most of my use case is for emergencies - in the cars, in the house, etc. But I am out in the woods a good bit (going today) for hunting - but I'm *probably* already "good enough" with what I have. (Example - I just figured out that one of my "travel kit" Zebra lights might be a better FL to carry into the woods than the SkyLumen XVIII - at least from a size perspective.)

Thanks again.

Yes, I'm all over the place.
The Bodyguard running on Li-ion does 8 seconds on high, then steps down. It also (unofficially) runs on AA primaries and Eneloops at a single mode of about 80 lumens. Quite useful at that 80 lumens. I also happen to have a Kosen Bodyguard for sale if you’re interested.
