3-wire |
 |
3-wire control is a
line-voltage phase-control dimming method. Along with Hot and Neutral,
the dimming signal is communicated via a third wire called Dimmed Hot.
All three wires are rated Class 1 and can be run within the same
conduit. 3-wire control is the Lutron preferred dimming technology - it
is stable over long wire runs, allows for maximum circuit loading, and
is very easy to wire. |

2-wire |
 |
2-wire control is a
line-voltage phase-control dimming method. The ballast receives the
dimming signal through the Dimmed Hot wire. Intended for small-scale
retrofit applications, the 2-wire control method is often the easiest
way to implement dimming in existing fluorescent fixtures. |

0-10V |
 |
0-10V control is a
low-voltage DC dimming method. Power wires are rated Class 1 and control
wires are rated Class 2. This separation allows multiple circuits to use
the same dimming signal without additional power equipment. 0-10V
control is not recommended for dimming below 10%, as fixture-to-fixture
tracking can be significantly affected by control wire length. |

Infrared |
 |
Infrared (IR) control is
a wireless dimming method that uses a handheld remote control or
personal digital assistant (PDA) to provide dimming. Infrared control
allows for simple personal control of individual fixtures or groups of
fixtures. In addition, IR-controllable ballasts can be trimmed to reduce
the maximum light output. |
