Led guys chime in

Just throwing this out there, but if any of you guys are doing a buildout, wire your ceiling for 220v. LED's are efficient on thier own, but at 220v, they'll draw 1/2 the amperage.
At twice the volts.. Volts x amps = watts. Watts are what you get charged for. Don't expect efficient billing.

LED drivers are more efficient when run at 220v.

From Meanwell datasheets:

Thanks for the charts!... I had spoke with my electrician (and lifelong friend) about this when I did my buildout. Pretty much what he said. 220v is cost effective. I did this where I could. So, If I were to have wired my ceiling at 110v, my lights would be pulling 82.8 amps, but at 220v, they are only pulling 36 amps (set up on 3, 20amp breakers). Hell, my whole grow building only pulls around 80 amps with everything on. He came out and put a meter on the box, and I fired up the shop vac, rez pump, all dehueys, AC, lights, and anything else I could think of. I have a 200amp panel to the building. I had so much room left, that I had him tie that box into a new 30x40 shop right behind the Grow building, but shit, it don't pull anything.... maybe 10 amps with the lights on and the compressor running.

Amps are the load. Wattage doesn't really matter. You're not being billed on wattage, you're being billed on the the KWH, which is directly correlated with your amperage load.
KilaWATThours.. you get billed for watts pal not amps.. If you want to talk about efficiency the only efficiency that you get is A220 Volt can run on a smaller gauge wire which causes less resistance on 220 V with the lower amperage so you have better efficiency that way but in a negligible way in real life nor on your bill nor anywhere else.
