The Malkoff Front Porch

Hi there TG, happy to see you still around;

My favorite emergency light is a SF C3 with my Neutral LLLL; three CR123's and I can't imagine how long it will run, lol. Also, 2xAA alkaline works very satisfactorily in a pinch. šŸ™‚
You as well siršŸ˜.
 
An interesting story, that SF C3. My first ever SF, running with a Malkoff M30 & 2xAA. I then had it bored for 2x18500 (remember those days? lol). It got over-bored which I was never too happy about. A couple years ago I purchased a carbon fiber tube with a perfect ID for CR123's (/almost/ snug but not quite). Had a machinist friend turn the OD on the CF tube for a precision fit to the C3 bore. Sometime šŸ™„ I'm going to get around to epoxying it in there. Should be strong after that. Will do a thread w/ pics on the story sometime. :-/

How many lumens does that provide ?
 
Ya something like that I have in my notes and all my runtimes. Iā€™ll take a look when I get home
 
I thought the LLLL was around 25-30 lumens.

EDIT: found this:

Oveready's M61N LLLL

3x CR123: 33.6ma @ 9V (27lm)
2x CR123: 37.3ma @ 6V (22lm)
1x CR123: 62.5ma @ 3V (20lm)

2x Li-ion: 35.3ma @ 7.8V (25lm)
1x Li-ion: 57.2ma @ 3.8V (20lm)
 
Ah OK, thx. I do recall that I sold my M61LLL when the N LLLL group buy wrapped up.

I'm wondering if that later Group Buy run used a more recent emitter compared to the earlier run(s) for OR ?

Edit: Here's the thread:

Output is estimated to be in the low/ mid 20 lumens. The LED is a will be a 4000K-5000K "neutral white" Cree XP-G2 LED, exact model yet to be chose.

And I see the "Usual Suspects", lol
5000K Interest List:
  1. marco.weiss Paid
  2. Not So Bright Paid
  3. thermal guy Paid
  4. dotCPF Paid
  5. PoliceScannerMan Paid
  6. Kestrel Paid
  7. Kestrel Paid
  8. bignc Paid
  9. Jimmyboots Paid
  10. bykfixer Paid
  11. thermal guy Paid
Edit: Some good reminders in that thread already; I see this:
I ran the original M61N LLLL on 2x AA in a G3, get's 20~ lumens. I should runtime test that.... but a 3x CR123 host is great for this dropin.

Reading over that GB thread from 2020; I had forgotten the 4000K version actually got SST-20's, so they would have been a littler brighter than the standard LLLL. Just FYI;

Edit: On the other hand;
I did not get to do any real testing yet, plan on trying some of that tonight. I did stick them in my LumensTube real quick, on 2xCR123 the 4000K SST LLLL was 21 lumens, and the 5000K XPG2 is 30 lumens. I'm thinking draw is a bit lower on these, as the 5K XP-G2 was about 30% more efficient than the 3000K 90CRI I used for the W M61 LLLL.That's a total speculation at this point though.

A MDC with a warm LLLL single level engine would be great. A nice long running 25ish lumen EDC for every day tasks.

We have the 4L M61's. With a VME head it's pretty close
I'd LOVE a M61WLLLL or M61NLLLL, because, with the VME, that would be great.
A M31WLLLL would be very cool, as that could run AA fine.

You guys know, if he beg Kosen enough, he'd probably make this happen. I'd asked him about some M31 drop-ins, but at that time, I was about the only person really interested. If he saw more demand, he's probably order some up and put them on the website.
 
Randomly found myself on the first page of this thread and saw this pic posted by @greatscoot ...

Can anyone tell me anything about the silver head on the orange MDC body??

Is it some sort of mule? Who made? Would love a super floody low lumen head like that.

Ah thanks, ouch that would be an expensive addition! And I have always wanted a Sapphire too, so that would make it even more of a hit
 
Take it off completely and don't lose the screws. Two different lengths on the screws. Make sure they go back in the same way. One holds switch in place. Wrap some tape around pliers and use them to bend the clip without marring

Finally found somebody with a tool to remove the screws šŸ™‚

The clip pressure is perfect now. Thanks, @ilikeguns40

Whatā€™s wrong with 18500s? I was considering doing the same thing for a C3
 
What's wrong with 18500s? I was considering doing the same thing for a C3
If the goal is capacity, an 18650-compatible 6P (or C2) takes a 3400 mAh 18650, which is pretty good.
KeepPower 18500's appear to have decent capacity, but I note that my overbored C3 still can't accept their diameter - we're talking over 19mm here.

(I can post back with measurements, but the typical 18mm boring job does ~18.6-18.8 mm.)

My C3 was mistakenly taken to ~19.2 mm IIRC which leaves too little wall thickness IMO.)

Here is a C2 that broke even while doing only light service:

Which is why I feel like the best use of my C3 is the LLLL discussed above (where 18mm-type capacity isn't really needed). I have plenty of other lights that are 18mm bored for extra capacity; all of them taking the 18650 which is still the capacity king of the smaller battery sizes.

Note that the 6P is a very popular 18mm-boring candidate, partially because it doesn't have the grip ring area w/ less wall thickness.
