Product Overview
GE T8 electronic ballasts are designed for high-frequency fluorescent operation, quieter performance than older magnetic ballasts, and efficient operation in office, retail, school, healthcare, warehouse, and commercial retrofit applications.
Ballast factor matters: lower ballast factors reduce light output and energy use, normal ballast factors balance output and efficiency, and high ballast factors increase light output where more illumination is needed.

Before Ordering Verify
- Exact GE Model: Match GE 87125 / GEM232T8RS120 to the existing ballast label or fixture documentation.
- Lamp Count: Confirm the ballast supports 2 lamp operation.
- Lamp Type: Confirm compatibility with F32T8 and any reduced-wattage lamps being used.
- Input Voltage: Confirm the fixture supply matches 120V.
- Starting Method: Match instant-start or programmed-start requirements, especially when occupancy sensors are used.
- Wiring Diagram: Follow the wiring diagram on the ballast label and verify socket type before installation.
- Case Size: Confirm the ballast channel has room for the listed case dimensions.
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 removing or installing a ballast.
- Grounding: Properly ground the ballast and fixture to reduce EMI/RFI and support safe operation.
- Do Not Bundle Leads: Avoid twisting or bundling lamp leads; excess wiring can create starting or performance issues.
- Use Correct Sockets: Programmed-start and dimming systems require rapid-start type sockets.
