APPLICATIONS
• Hotel Ballrooms • Conference Rooms
• Audio-visual Rooms • Public Spaces
• Restaurants Fluorescent lighting is an extremely efficient light source. With the latest electronic solid state fluorescent dimmer ballasts, they can be dimmed effectively. Most fluorescent lamps today can be dimmed to approximately 5% of full bright with the appropriate dimming ballast. Compact fluorescent lamps using dimming ballasts are now replacing incandescent down-light sources in many applications.
Leviton Lighting Control Division makes a complete line of fluorescent dimmers, that are able to operate virtually any dimming ballast by any of the different manufacturers. Because there are many ballast manufacturers, there are many different ways to control the various dimmer ballasts. To supply the correct dimmer we must know the ballast manufacturer and the exact model number of the ballast, as well as the incoming line voltage to the ballast.
Leviton Lighting Control Division supplies fluorescent dimmers individually where only a single circuit of fluorescent lighting is controlled, or we supply one or more fluorescent dimmers as part of a larger system with mixed loads. Any of our extensive line of lighting controls can be used with our fluorescent dimmers for fluorescent dimming ballasts.
dimmer Module for
There are two basic types of solid state fluorescent dimming ballasts. One type is designed for the retrofit market, where the original ballasts installed were not capable of dimming, and are now being replaced by dimming ballasts. These ballasts are designed to operate with the existing two wires (a hot and a neutral), that fed the original fixture. The ballast is changed, new lamps installed, and a dimmer is inserted to feed those fixtures.
The other type of solid state fluorescent dimmer ballast uses two low voltage wires to control the intensity setting of all the fluorescent lamps on a circuit. These are normally used in new construction where there is little extra cost involved for running the control wires back to a dimmer location.
Since none of the ballasts are intended to dim to blackout, Leviton Lighting Control Division furnishes an ON/OFF contactor that turns off all power to the ballasts when the system OFF switch is operated.
There is an older type of dimmer ballast called “magnetic” or “core and coil” which is still manufactured. Leviton Lighting Control Division does make dimmers for these ballasts, however, these ballasts are not recommended for new construction as they will be phased out over time. Dimmers for these ballasts should be considered for replacement only, not new construction.

LOW VOLTAGE CONTROL
The diagrams on this page illustrate typical wiring of dimming ballasts using two control wires between the ballasts and the controller. Any Leviton Lighting Control Division remote controls can be used, as well as time clock control and photocell control for automatic daylight harvesting. As the diagram illustrates, an ON/OFF contactor or line voltage switch is required to turn the system off since the ballasts dimming range is down to 5%, and most applications do not want this low light level to stay on when a room is not occupied. The line voltage feeds through the contactor directly to all ballasts on the circuit to power the ballasts. Dimming actually takes place within the ballast, the low voltage control signal tells the ballast what light level is desired. Since the control signals are low voltage (10 volts DC) and current limited, the control wiring between the ballast and the Leviton Lighting Control Division controller can be Class II wiring. Depending on local electrical codes, this wiring may not need to be run in conduit.
The wiring shown is typical of the Advance Transformer Co Mark VII™, the series of dimming ballasts. Several other ballast suppliers are using this same control scheme.
CONTROL OPTIONS
• Manual Control System
• Remote Preset System
• Designer Preset System
• Automated Control System
The typical dimming ballast of this type requires about one half milliampere of control current, allowing the Leviton Lighting Control Division dimmers for these ballasts to typically control up to a maximum of 100 ballasts. The on/off contactor is normally rated at 20 amperes since the typical lighting circuit is a 20 ampere circuit.
More than one dimmer can be controlled together for larger lighting loads, to allow a whole ceiling with multiple circuits to dim uniformly up and down.
The diagram at the top of this page shows the physical layout of a stand alone dimmer for these ballasts. It is a surface mounted unit 12 " x 12" x 3" deep box with a one inch mounting flange on two ends.
The systems version of this dimmer is built in single and dual modules that fit the standard MDS dimmer cabinets shown elsewhere in the Leviton Lighting Control Division catalog. They take up one 4 inch dimmer space in any of the cabinets shown there.

TWO WIRE VOLTAGE CONTROL
down to 5%. In this case a line voltage switch or contactor is needed to turn the power off when the room is unoccupied. Dimmer ballasts of this type presently on the market require an adjustable low light limit control to be incorporated into the dimmer module to set the low light level to 5%. Allowing the lamps to go lower than this can result in shortened lamp life.
Basic Field Wiring Schematic
This drawing illustrates typical wiring of dimmer ballasts using the line and neutral wires to both power the ballast and control the light level of the fluorescent lamps, such as Advance Mark X. ballasts are specifically designed for (but not limited to) the retrofit market. They are ideal where the original ballasts installed in a room were not capable of dimming, and are now being replaced by dimming ballasts. These ballasts are designed to operate with the two wires, a hot and a neutral, that fed the original fixture. The ballast is changed out, new lamps are installed, and the existing building and fixture wiring is reused. No separate control wires are required. Wh e n power is turned on the lamps come to full bright as usual. However, if a solid state dimmer is inserted into the line feeding the ballasts, it is possible to set the light level of the lamps anywhere from full bright

There is another type of ballast that uses line voltage dimming as above, but that requires an additional third wire supplying a constant line voltage to the ballasts, as well as a variable or dimmed line voltage. Because these ballasts require adding a third line power wire between the ballasts and the dimmer unit, this type of ballast is not well suited to retrofit applications.
