P60 drop in that runs on 1xCR123A

I am search for a P60 style drop in that runs on 1 cr123a for use in a older surefire 3P, I tested the fit on a malkoff unit and it fits fine but needs a different driver. Any help would be great.

Primaries or Rechargeable ?

A lot of drop ins start @ 3v and wont power up at all with primaries .

Seems nailbender can make you one

"Low power special. I have a new driver that is a boost driver and works with XPG quite well, I can now make modules that will work full power with a AA battery or 1Xcr123 primaries. "

Thanks, I shot nailbender a pm.

The Malkoff M30 won't work?

I would definitely go for the Malkoff M-30. I have an FM 1 cell tube with Surefire head and tail cap that is about perfect.

If you decide to go with Solarforce, be SURE to get one of the .8v-4.2v dropins. They offer single mode, three mode and five mode. I have at least one of each, and they all work great.

The 4.2v-8.4v dropins won't work 1xCR123. Neither will the 6v-18v single mode - but I bet this last one gets some killer runtimes at 9v or more!

There are 2 Malkoff units: M60 and M30. The M60 is for multi cells (over 3.7V) and the M30 is for single cell use (like a single 18650 or 123).

Any 3V incandescent dropin suggestion?

You want a LED based P60 drop in that can run on 3V? Both Nailbender and Dereelight have P60 drop-in that can run from 3V (or less).

Either incan. or led is fine.
I am looking for cheap drop-in which can run full power with the FM 1x CR123 body.

Well, I don't know much about incandescent P60's, but the Dereelight and Nailbender LED drop-ins are about $35-40 and use the latest Cree XP-G R5 LEDs.

Bigchelis tested a few low-voltage LED P60 dropins for output at ~2.4v (2xAA, but pretty much the same voltage you are looking at) and the XP-G Dereelight Javelin drop-in came out on top (200-250 lumens), way ahead of the low-voltage Solarforce. The Nailbender is probably competitive as well. The Malkoff M30 is a great unit but getting a bit dated, it does ~160 lumens from 1x CR123.

I use the M30 with two NiMh AA's as well, and it holds steady at 1A draw at the tailcap. I use Eneloops. I would guess that XP-G's delivering 1A to the LED would be pulling close to 3A's at the tail.

I would expect a good P60 to pull considerably less than 2A from the battery in order to deliver 1A to the LED from 2xAA's.

A good boost driver should be about 90% efficient so to put out ~3.5W (1A) it needs to use ~3.9W, which is 1.6A from 2xAA's (2.4V).

I wonder how M60LL would work on 1x123.

If you want an incan, try the lumensfactory bulbs: http://lumensfactory.com/cart.php?cat_id=2&sub_cat_id=1
They're only for 3.7V rechareables though.
