[QUOTE="Terryl, post: 1105872, member: 369937"] My main concern is that there will be 110/120 volts on each side of the bulb,(center button, and base) not 220/240 volts on the input (center button) and zero on the base (neutral) like in the UK and other Country's. Our 220/240 volt power here in the US is a dual phase delivery system, phase 1 = 110/120 volts, phase 2 =110/120 volts type setup, not 220/240 volts on one phase to a device then a neutral, we don't use a neutral for this setup with 220/240 volt motors. So you see the bulb in question will be connected to a dual phase power input, 110/120 on both. Since the LED bulbs use an AC to DC rectifier and run on a DC voltage I don't think the 10 Hz difference in line frequency will matter, my concern is the dual phase power. I wish I could pull a neutral wire into the conduit feeding the motors, but they are too full to do so, and the conduit is PVC so I can't use it as a ground and the old ground wire as a neutral, bit of a problem huh.
