GE 75381 0-10V UltraStart T8 Dimming Ballast 3 Lamp

SKU CH-4HCA-FVH2J

A 0-10V dimming ballast operates three T8 lamps with parallel operation and anti-striation control from 120 to 277 volts

  • Controls 3 lamps per ballast for efficient coverage
  • Dims smoothly from 100% to 3% via 0-10V programmed start
  • Operates on 120-277V multi-voltage for flexible installation
  • Parallel operation keeps remaining lamps lit if one fails
  • Anti-striation control supports F32T8, F28T8 and 2-3 ft T8 lamps

GE 75381 0-10V UltraStart T8 Ballast

The GE 75381 is a programmed-start electronic ballast designed to operate three linear T8 fluorescent lamps. It accepts a multi-voltage input ranging from 120 to 277 volts, making it suitable for commercial lighting installations. The unit measures 9.5 inches by 1.7 inches and is sold in a case of ten.

Sustained load dimming stability

Programmed start circuitry reduces electrode stress during ignition to extend lamp life across daily cycles. Parallel lamp operation ensures the remaining lamps stay lit if one fails, maintaining illumination levels. Anti-striation control supports smooth, flicker-free deep dimming down to 3 percent output with compatible lamps. The 0-10V interface provides consistent analogue control for building automation systems.

Build quality and wiring implications

The compact case dimensions allow installation within standard fluorescent fixtures and narrow plenums. Multi-voltage technology automatically adapts to 120 or 277 volt supplies without manual rewiring or tap changes. It supports F32T8, F32T8/WM, F28T8, and two- or three-foot T8 lamp types for retrofit flexibility. Electronic construction reduces maintenance compared to magnetic ballast alternatives.

Questions about this item

How much heat does the 75381 ballast produce when running three lamps continuously?

The multi-voltage 120-277V design runs efficiently across the full range; with parallel lamp operation the unit maintains stable output without extra cooling in typical ceiling plenums.

Which lamps must I already have for the 75381 to start and dim properly?

Compatible lamps are F32T8, F32T8/WM, F28T8 and 2 ft or 3 ft T8 types; the anti-striation control and programmed start method are tuned for these specific diameters and wattages.

Will the 75381 work with my existing 0-10 V dimmer and older T8 fixtures?

Yes — the 0-10V interface dims from 100 % down to 3 % and the 9.5 x 1.7 inch case fits standard T8 channels, while multi-voltage input accepts legacy 120 V or 277 V wiring.
