Malkoff P7 Direct Drive Drop-In (Photos)

This is a light that is at it's best for two things that I can think of myself (and better at these than most anything else that I'm aware of)

• broadly illuminating a room without distracting hot spots

• being blisteringly bright in momentarily rebuffing an assailant

While I would definitely take other flashlight choices (like the M60) over the Malkoff P7 as a general outdoor light, I very much value the Malkoff P7 for its abilities in those two areas.



So would you recommend this light for some night hiking or camping?

Thanks!
 
swrdply... I would not recommend the P7 for night hiking or camping. For those applications, I think the M60 (for 2-cells) or M30 (for 1-cell) would be just great! A great, bright central beam to focus on the semi-distant trail ahead or interest area, with a nice spill light for closer-in ambient vision. In a camping setting, the P7 would be of most value in evenly illuminating the immediate campsite, NOT for illuminating more distant areas of interest.
 
Is a MP7 used with (1) CR123 Safe? or should I only use the 18650?

A P7 will want to draw close to 2.8 amps from the battery and a CR123 will not sustain that kind of current damand, and full brightness of LED will not be achieved, due to voltage sag. A Li Ion, particularly a high current Li Ion, will be needed to achieve highest output, and any kind of runtime, so yes an 18650 would be best.

Well the specs for the Titanium 123 from battery junction show (picked because it's the first discharge rate google found for me)
Max. Constant Current 1500mAh
Max Pulse Current 3000mAh
PTC High Current Discharge Protection
5AMP
Silverfox did do 2A draws on cells in the 123 shootout including the titanium. He mentions that 123's get hot at 2A. That's one more heat source in a small light. Put it together and I wouldn't want to try and pull 2.8 amps.

Except this module is direct drive and probably can't pull that much. Looking at the P7 spec sheet typical Vf at 2.8A is 3.6 - more than the cell provides unloaded. Typical Vf at 1.4A is 3.3 - so exceeding safe current also requires more voltage than an unloaded cell provides. Good news.

Voltage will dip under load too. Looking at the battery shootout it drops just under 2.5 volts with a 1.5 safe amp draw. Typical forward current at 2.5 volts is a big fat zero - no light but no :poof:. At 3 Volts you get forward current that's maybe 400mA. Even at that draw the cell won't maintain 3 volts though. So with a typical Vf you are looking at less than 100ma per die. You would need a very low VF LED to push the max draw limit.

It's probably safe (I'd check tailcap draw the first time I did it as an indirect check for low Vf). It's probably not going to be as bright as a cheaper M30 with a primary though. A primary might make a backup but I wouldn't buy this to use with one. If you really want a 1x123 form factor with this module think IMR 16340. :thumbsup:

Disclaimer - I assume no liability. Proceed at your own risk. I make no claims of accuracy or actual safety. I am frequently wrong about anything and everything. Anything I think might be safe could actually result in immediate apocalypse. You should investigate reference material on your own and make your own judgement. Red Ryder BB guns will "put your eye out kid."
 
Thanks. I have both an M30 and P7 and I just ordered a 3P so I thought a P7 in it would be cool. But I guess not now.

Optik... we're thinking along the same lines... I have an MP7 and M60F and also have an FM 3P body coming... it will be interesting to see what the MP7 lamp assembly does with the 6P head, 3P body and an IMR16340. From info given by those that have contributed here and elsewhere, it sounds like the IMR16340 is really the only advisable 123 size cell to use for the P7. I know it won't last very long, but can still give good utility for certain applications. For one, it would make for a good self-defense light on the street... being fairly small for pocket carry and also providing enough temporary blinding effect to buy a few seconds to bring your weapon into action. Also, room sweeping.
 
Does any one have outdoor beamshots and distance shots?

Beamshots from 3 floody lights...

MTE SSC P7 - 1*18650

Malkoff M60F - 2*RCR123

The M-P7 has practically no beam... just wide, relatively even illumination.

The M60F has a bit of a focused beam, and a wide floody spill

The MTE SSC P7 has a bit of a focused beam as well, with a lot of wide floody spill.

Optik 49,
The 3P variations brought tears to my eyes........:mecry:

They are too dam good. I like what you did.
Are you using the AW16340's or the new 18350 with more mAh?????????
