Yes, just the Spark SD6 and ST6.
The SD6 is pure flood, with no reflector, or an optional small reflector for only $10.
The ST6 has a bigger reflector for more throw.
However, both only output 500 lumens.
Like Skyfire says, it will take 2xCR123's @ 2x3.0 volts, but I'm not sure if it will take 2x16340's @ 2x3.6 volts, because the working voltage range for these lights is from 1.6 volts to 6.8 volts.
On the otherhand, the Zebralight H600 weighs a lighter 39 grams on the head, yet also outputs 750 lumens, but it requires an 18650; it will not accept 2x CR123, let alone 2x 16340's.
An 18650 charger like an Ultrafire charger is only US$15...
