• Step dimming
• Installation flexibility - Ballastar® light level switching products make it easy-to implement controllable lighting solutions with only one additional line voltage conductor
• Ballastar® ballasts can be controlled using two standard toggle switches, no sophisticated control devices are needed
• Modern level switching technology - Ballastar® light level switching ballasts vary the light output of all the lamps, eliminating fixture dark spots associated with inboard/outboard switching schemes
• Control options: application of the Ballastar® family is not limited to manual control with toggle switches
• Other control options, like occupancy sensors, building management technologies or any other device using a contact closure, can be implemented with Ballastar®
• Easy system setup: Ballastar® light level switching ballasts are shipped from the factory with predefined light levels, no programming is required
• Ballastar® T5 products provide two predefined control levels - 50 and 100 percent of the rated input power, these ballasts are featured with universal input voltage (120 to 277 VAC) for installation flexibility
• Ballastar® S30 products for T8 lamps provide three pre-defined control levels - 30, 60 percent and the standard 0.88, dedicated voltage ballasts for 120 V and 277 V systems are available
