RADIA Lighting Control System
DC-Controlled Electronic Ballasts (4-Wire Ballasts)
The DC-controlled Electronic Ballasts track a 0-10 or 0-12 VDC channel for dimming and an AC switch
channel for on/off. This ballast design is better than magnetic, but many stop dimming at about 20%
brightness. That's fine for energy management and secondary lighting zones, but not for primary lighting that
requires precision, low-level dimming control.
The following table lists compatible DC-controlled electronic ballasts.
Ballast Interfaces and 2-Wire Ballasts
In some cases, dimmers are wired to ballast interfaces (provided optionally by lighting suppliers), rather than
directly to the ballasts. A few interfaces are driven from a standard AMX Lighting incandescent channel, while
most use FDB dimming configurations.
The following table lists compatible ballast interfaces.

Notes:
1. The Lightolier ballasts require a proprietary DC-signal interface (including low-level trim). The AMX
Lighting controller module handles load power.
2. The Lutron HP-2, 4, and 6 interfaces accept 120 VAC input. The load can be 120/277 VAC (including low-
level trim). Interface includes power control to ballasts.
3. The Lutron GRX-FDBI accepts 120 VAC input. The load must be 120 VAC. Interface includes power
control to ballasts.
4. The Prescolite ballast interfaces are optional. The AMX Lighting controller handles load power.
