Which is brighter led w/ 2 123;s or 1 x 17670

I am wondering what would be brighter. I have a surefire 6p with a R2 drop in. I can run 2 123 primaries or one 17670 cell. WHich would yield higher output. I assume the 17670 cell would give longer run time.

Definitely true for incan; not necessarily through with a led.

Depends on regulation of the unit, etc. In general, the brightness of the led will be determined by which delivers more current - the led's vf will determine the voltage across the led and not the batteries.
