Did you account for driver and wiring losses? you need to subtract those to know what your boards actually are drawing. Wiring just figure about 2 watts. Driver loss is about 5% of the total.
still seems high for the 185HI'll check mine, I have three of them running
Also, voltage seems pretty high, here are the ( I assume average ) specs for a V1 @ 2100ma

Have you made adjustments to the voltage? ( the Vo adjuster )
Lastly, did you check the voltage at your AC outlet? V should be 115V, not 120V.
