Some people use a 16650 (or 18650, which is a bit fatter) but the voltage is a bit lower which could reduce the light output.

is there a single battery that takes the place of the two?
Side by side or end to end? In some cases, you can use one CR-P2 (223A) battery or two CR123A cells interchangeably where the mechanical configuration is side by side, the electrical configuration is series connection and the contacts are suitably designed.
Lithium rechargeable 17670 is mechanically the size of two CR123A cells end to end, but at 3.7V rather than the 6V the device was expecting it's a matter of experiment to see whether it's a viable alternative. Some inverter driven circuits will be fine with it as they are expecting to see <2V/cell from a CR123A towards it's end of life.

I have an old taclight which takes two CR123 batteries. My question is; is there a single battery that takes the place of the two?
