Re: when will Malkoff update their dropins?

Looking forward to see what Gene eventually releases.:grin2:
I would suspect that he will continue making the optic variety of drop-ins simply because of his excellent MD2 which has no lense of its own.
Of course it is possible that Gene could source a suitable lense and supply it with the MD2.

Re: when will Malkoff update their dropins?

There are lenses available from flashlightlens dot com that will go right in. If Gene doesn't already have a lense option to go in front of any module he makes with a reflector that will need one, I am sure he will find a suitable one.

A module with a reflector that would need a front glass lense would be awesome to have a AR coated lense in front of it. They are already out there so this isn't really a concern.

Now do you guys really think Gene is going to make a module that isn't compatible with his own host bezel/head. Especially when the VME head is designed to take P60 type drop in modules, mostly his!

That's like hoping the pope would do a "catholic" mass on Sunday morning, as if he would do anything else. :thinking:

Actually, I think he might use a 26mm reflector, particularly if we expect some thrown with the XP-G. Who knows, maybe a new MD head with larger window opening, and look at all those SF, and SF clone bezels out there. Now, don't beat me up. :devil:

Re: when will Malkoff update their dropins?

Just happened to do a runtime with an 18650 in my MD2, using bounce with a light meter, and over a period of 105 minutes output dropped 13%. Starting output lux number with the 18650 was the same as using two 18500's. Pretty outstanding.

Bill

With M60:
IME, 2x18500 config was brighter than 1x18650.

However, I get better runtimes with the latter than with the former. I use unprotected Panasonic 2900 mAh cells in 1x18650. Of course you can visually tell when it drops below 3.7V (Unlike with 2x18650 cells)

With fresh cells, both will start out regulated, so shouldn't the output be roughly the same?

I'm clearly missing something here.

And it was very similar but M60 on 2x18500 was clearly brighter by a small margin than on 1x18650, I would say the difference was about 180-200 lumens vs standard 235 lumens. There is something about 2-cell configuration that makes it run in this "Turbo"-like mode that you cannot get on 1 cell.

As I said, the cool thing about 18650 cell is that you can use unprotected high-capacity cells at almost 3000 mAh, not AW cells that are still stuck at 2600 mAh.
Secondly, at lower voltage and lower lumens you get better runtime and non-using protected cells, you get a long tail between 3.7V, which it gets out of regulation and 3.5V, when it's discharged. The practical thing about it, it won't suddenly cut off on you like AW cells, this can be *vital* in mission-critical environments where I would never use protected cells to begin with (and may not Li-IOn at all)
The third cool thing about it, it's very compact versus 9P form factor.
Lastly, 18500 are still kind of low capacity, they are just very slightly smaller than 18650 but the capacity is still only 1500 mAh, whereas 18650 is pushing 3,000 mAh. So you get longer (regulated) runtime with 1x18650 versus 2x18500, albeit slightly fewer lumens.

I would post a pic of the two side by side but I just traded my M60 module for M60L and no longer have it. But it makes sense, think about it - of course it should run brighter on 8.4V versus 4.2V, even in regulation.

FWIW the lightmeter data that I have seen on this (1 large LiIon vs 2 LiIon and the M60):
  • Bullzeyebill: zero difference
  • DHart: ~10% difference (M60 was ~10% brighter on 2x LiIon vs 1x18650 IIRC)
I have my M60 beamshot photos of both configurations posted here. I find it extremely difficult to discern any visible difference in output for my M60 between these two configurations. Maybe it depends on the Vf of the individual LED in each M60 module? :shrug:

If others are interested the main thread for this aspect is the Malkoff M60 & M30 Runtimes thread IMO, there is a lot of info there.

Did anybody see a Malkoff booth at the Shot Show? Maybe he would have shown some proto-types there and give us a peek at some new goodies.

M60__from Regulated power supply,

3.5_____0.38____1.33__,

8.4_____0.50____4.20__,
8.5_____0.49____4.17__,
9.0_____0.47____4.23__,

This is my data on power consumption of an M60 using a DC power supply. At 3.8V its down to 2.5 watts and at 6V its steady over 4 watts. I have measured the lumens output but never published it and the M60 is definitely dimmer off of a 3.8V lithium ion battery. It won't hold the 4.2V under load so its not going to be as bright as with a pair of CR123 or higher voltages. An M60 is about 50 lumens lower in output but will run longer off of an 18650 battery.

:poke:anyone?

Hey Gene... No that shot is over is there any chance of getting more details on your new XP-G M60/M30 series?? :whistle:

Did anybody see a Malkoff booth at the Shot Show? Maybe he would have shown some proto-types there and give us a peek at some new goodies.

CALM DOWN GUYS!! :D

I did speak to Gene at the 4Sevens & MattK parties and heres the short/long of it:

He's still working on the XP-G and he will have a testing prototype out soon. I can say that Gene did show us his working sample that he had. One word: BRIGHT! except it has a more intense flood when compared side by side to a M60. For you reflector fans out there, yes it will be all reflctor, no optics.

That's all I can say based on my short time looking at the light. Hoping Gene will pop in here and post more info. THANKS Gene!!! :thumbsup:

Re: when will Malkoff update their dropins?

Did the reflectored design still have his standard M60 solid Brass heatsink with the reflector built into it instead of the optic?

Yes. Gene is still working on the module design, so nothing is final yet. The reflector is unique and Gene may want to talk about that later. Re an earlier question, Gene did not have a booth at SHOT.

Thanks for posting this. I was recently searching for this kind of data on the M60. Running it on a 1x18650 is enjoy the fact it falls out of regulation and dims over time. Gives a nice heads-up on the state of the battery.
