Valance Lighting

A fixture installed behind a horizontal shielding over a window or along a wall. Light is distributed up and down, usually from a fluorescent source.

Volt

Unit of electricl force or pressure. Household voltage in the United States, nominally 120 volts, varies between 110 and 125 volts.

Voltage Drop

Difference in voltage along a circuit. Voltage drop becomes a problem with low voltage wiring and small cable, reducing the intensity of the lights at the far end of the cable.
