1xcr123 + p60...suggestions?

I might be able to pick up a dereelight c2h body with a dereelight javelin head...now all I need is a p60 drop in to go with it.

I was told both the 1 and 5 mode xml from KD would work? will it with a standard 3v cr123, not 16340.

If not, I take it an xpg r5 would be the next suggestion for max output?

I'd like to spend less than $20 on the drop in if possible, so any suggestions would be great as I'm pretty new to drop ins etc..

Perhaps this one:


- Battery configuration :
18650 3.7v x 1pc
CR123A 3.0v or 3.7v x 1pc

- Runtime : 18650 3.7v – 3.5 hours CR123A 3.0v or 3.7v x 1 – 1.5 hours

Make sure you go 0.8v to 4.2v Low voltage drop in if you plan on running primaries ...

The normal 3v to 4.2v drop in will not run on primaries , nor will the 3 - 8.4v one .
