A transformer that has the ability to accommodate several voltages.
Multi-tap
Answer
Parallel Run
Answer
A parallel run allows all fixtures to draw current independently of the other fixtures. When one light goes out, the others will stay on.
Photometrics
Answer
A measure of a fixture’s actual light output at various distances.
Power Supply
Answer
A power supply, otherwise known as a transformer, is generally used with low voltage lighting to “transform” or reduce line voltage to 12 volts. Without a transformer, the lamps would be subjected to excess voltage and would burn out immediately.
Resistance
Answer
Electrical pressure on the wire, impairing the flow of electricity.
Splice
Answer
To join together two or more wires by interweaving and applying a waterproof connection.
T
Answer
A “T” consists of running a low voltage cable to a centralized zone, then running other cables off the “T” to fixtures. It equalizes voltage and removes the error of over exposure at the first lamp.

Volt
Answer
Measures the pressure through a wire.
Voltage Drop
Answer
The degree in which voltage is diminished, affecting lamp performance.
