If I'm interpreting the datasheet correctly, they may not actually be stepping down the voltage at all after its rectified, in which case each LED will have a drop of 120/14 = 8.5 volts. The current looks to be 80 mA through the LED string off of 120VAC. I'm unfortunately unable to directly measure it without taking off one of the LEDs, which would be quite difficult and I would have to use soldering equipment in one the labs.
