New Malkoff Flashlight: MD2 (Part 2)

[Gene43]

I started into a long winded deal and then thought better of it.

 

[Sgt. LED]

Thanks for the word Gene! I didn't know what it was but I did like it, and I should of put a dash between the 4 & 5!

Anyways, I'm really loving the M30WF low! :thumbsup:

 

[StandardBattery]

OK 4-5sec. Thanks for chiming in Gene. And it is not related to the two level ring correct?

 

[ANDREAS FERRARI]

It could be the light has an issue with or without the two level switch, that would make more sense.

It's just a byproduct of the driver design.

You were right StandardBattery when you said it was something other then the ring!!!It's the driver,not the ring!

 

[Gene43]

Correct. It is not related to the two level ring.

 

[StandardBattery]

Ya, but I was not right about it being a sign of an issue exactly because I got hung up on the 45secs that turned out to be a typo, and the fact that i did not notice it on my sample. The after-glow, is less than a 2sec fading wimper on mine. It's good that it was identified though and it was more interesting than waiting for the flashlight delivery person.

 

[StandardBattery]

On my 2 level retaining ring, I'm measuring ~75.5 Ohms. With a 4Voc cell ~46.3 mA on low (M30W).

Just arrived my Malkoff MD2 with high low ring. I LOVE this light. With the M60 in it and recharables it is my new EDC. The hi/lo is very nice as thats how I use a light on a daily basis.The low is perfect for small things not blinding and run time and the high spot and spill are perfect for a defense light.Man I could have used this light for the last 40 years.Awesome That being said I wish it had a anti roll bezel. Maybe flat black HA with a standup tailcap twisty for the non clickie lovers. Perfection. Thanks Gene I,m a happy dude. Wish it would hurry up and get dark.

On my 2 level retaining ring, I'm measuring ~75.5 Ohms. With a 4Voc cell ~46.3 mA on low (M30W).

I've modified the resistance for my switch to ~24ohms. It's drawing ~ 130mA, and delivering about 10lumens, maybe slightly less. It looks pretty much the same as my E2DL on low.

I've used a parallel resistor and my quick calcs show I can't go any lower without exceeding their wattage ratings, and I may actually already be too close because I don't know the wattage of the stock one.

Does the new resistor ring switch cause any reduction in output in the high mode with a M60 or M30?

[Gene43]

No. The resistor is bypassed on high.

 

[Mjolnir]

A system with somewhat modular resistors would be really neat, but I'm not sure how feasible it would be to make the resistors easily removable. Having a customizeable low mode sounds very appealing.

 

[kyhunter1]

Thanks Gene, that is just what I wanted to hear.

No. The resistor is bypassed on high.

Just got mine in camo MD2 with the 75 ohm resistor two mode ring. :twothumbs
Works great, beautiful camo green finish, high/low mode is flawless.

So you can see that with higher voltage it starts at a higher peak but the driver warms up some what and the output at 3 minutes drops below running it at the more moderate 7.33V range that would come from 2 RCR 123 style batteries under load. The light is generally about 5% brighter in the Solarforce host with a plain bezel (no crenellations sticking out and no glass than the MD2 bezel but I don't consider 5% significant in total output. I wouldn't run a Solarforce host with no glass in it. With AR glass the MD2 is in the lead, and with the plain glass that the Solarforce type hosts come with or even the original glass of a SureFire 6P, the MD2 comes out ahead. Hope this helps. G

Just got my camo MD2 and ring. If that ring ain't slick I don't know what is. Of course I had to get one more M60 while I was at it. Loving it.

 

[Bullzeyebill]

MrGman, would you try your MD2 M60 module in a two cell SF type body without a window, for comparison? Without resistor ring of course.

You want the bezel left on but no glass in the bezel? I have done tests with other M60 modules with no bezel at all and I am holding the module in place in the housing to insure tight contact. Does it have to be an actual Surefire bezel with no glass? I have not had any luck opening up the retaining ring to take the glass out and I don't want to ruin it just for a test. I normally use the solarforce bezel of which its very easy to open up and take out or change the glass on top of a 6P or a C2 body. I could easily do that maybe tomorrow.

If you have a 6P bezel that you took the glass out you can send it. What are you getting at, how much the window opening of the MD2 might cut off the light of the module since it comes slightly inside the M60 housing perimeter? Or???

Anyway did I mention how I loved the custom individual hand done green camoflauge looks on the host and that it clicks so good. And that its very drool resistant from all the guys at work who ain't got one and sad to say probably never will. Also I am quite impressed with how well the 2 stage ring works and at 18 lumens using the higher voltages of the AW RCRs that its a very good useful "find your way around the house" level.

 

[Bullzeyebill]

No, your SolarForce bezel without glass would be fine. Am looking at any differences there might be noted comparing the Kroll switch with your switch used with the SolarForce body using two CR123's or two RCR123's, using the same testing procedure you used with the MD2. In the end maybe the only difference will be the deeper set of the M60 in the MD2. I am thinking that maybe Gene has done a good service by offering a nice high current Kroll switch, and one I will buy (actually several). Previous Krolls have had high resistance, but Gene has asked for better from the Kroll switch maker, Judco.

Well I just ordered a switching ring and M60LL. Anybody done a runtime test on low with an M60LL yet? Preferably 2 RCR's?
