GE 68966 GE132-MVPS-N-S30 T8 T8 Bi-Level Program Start Step Dimming Ballast

GE 68966 GE132-MVPS-N-S30 Bi-Level Step Dimming Ballast – 1 Lamp F32T8 – 120-277V

The GE 68966 GE132-MVPS-N-S30 is a GE UltraStart electronic T8 dimming ballast designed for commercial fluorescent lighting systems requiring program-start step dimming. This ballast operates 1 F32T8 lamp with 120-277V universal input and provides 100% / 30% bi-level step dimming.

This is not a 120-lamp ballast. The S30 suffix identifies the step-dimming family, not the lamp quantity. This ballast should be matched by GE order code, model number, lamp count, lamp type, ballast factor, dimming method, input voltage, control wiring, and fixture wiring diagram.

Product Overview

The GE132-MVPS-N-S30 is designed for commercial T8 fixtures where a lower light level is needed through a step-dimming control strategy. The ballast switches between full light output and a reduced output level, helping reduce energy use while keeping the space illuminated.

Program-start operation helps extend lamp life in frequently switched applications, making this ballast useful for occupancy-controlled spaces, energy-management retrofits, classrooms, offices, and commercial buildings.

Before Ordering Verify

• Exact GE Model: Match GE 68966 / GE132-MVPS-N-S30 to the existing ballast label.
• Lamp Count: Confirm the fixture requires a 1 lamp F32T8 ballast.
• Dimming Requirement: Confirm the project requires 100% / 30% step dimming.
• Input Voltage: Confirm fixture supply voltage is 120-277V.
• Ballast Factor: Confirm the 0.88 normal ballast factor matches the desired light output.
• Socket Type: Program-start and dimming systems require compatible rapid-start type sockets.
• Wiring Diagram: Follow the wiring diagram on the ballast label before installation.

Safety & Installation Guidelines

• Qualified Installation: Ballasts should be installed by qualified personnel following applicable electrical codes.
• Disconnect Power: Turn off and lock out power before servicing the fixture.
• Control Wiring: Verify step-dimming control wiring before energizing the system.
• Grounding: Properly ground the ballast and fixture to support safe operation and reduce interference.
• Use Compatible Lamps: Confirm lamp type, lamp count, ballast factor, and socket type before installation.
