GE Lighting 73234 UltraMax Load Shed Dimming Ballast case of 10

SKU CH-2VMS-6V3G1

Case of ten 32-watt T8 electronic ballasts with 0-10 V load-shed dimming, multi-voltage 120-277 V operation and anti-striation control

  • Controls 1-2 T8 fluorescent lamps for flexible fixture design
  • Load shed 0-10 V dimming reduces energy use during peak demand
  • Multi-voltage 120-277 V input simplifies installation across sites
  • UL 55 °C ambient rating ensures reliable operation in high heat
  • Case of 10 ballasts supports volume projects with single order

Commercial retrofit fit

This case of 10 GE Lighting 73234 UltraMax ballasts drives one or two F32T8 fluorescent lamps at 32 watts each using instant-start ignition. The 0-10V load-shed dimming interface lets building-automation systems reduce output during peak-demand periods, while multi-voltage input accepts 120 to 277 V without rewiring. Anti-striation control keeps light quality consistent across the dimming range.

Thermal and electrical endurance

A UL 55 °C ambient rating means the ballast maintains full specifications inside hot plenum spaces where lesser units derate or trip. The high-temperature protection circuit cuts power before components exceed safe limits, then restarts automatically when conditions normalise. UL Type CC rating confirms the housing resists arcing faults that can occur during lamp failure or wiring errors.

Pre-installation checklist

Verify that each fixture uses F32T8 lamps and that the line voltage at the site falls between 120 and 277 V. Confirm the control wiring supports 0-10 V signalling and that the 9.5 x 1.7 x 1.2 inch housing fits the existing ballast compartment. Buyers needing program-start operation or three-lamp operation should select a different model.

Questions about this item

How much heat does the 73234 ballast generate when running all day at its UL 55C ambient rating?

The ballast carries a UL 55C ambient rating and a high-temperature protection circuit, meaning it is designed to operate continuously in environments up to 55 °C without overheating.

What lamps and wiring must I already have to install these 73234 ballasts?

You need one or two F32T8 fluorescent lamps per ballast and a 0-10 V dimming control circuit; the multi-voltage input accepts 120 V or 277 V supply wiring.

Will the 73234 ballast work with older magnetic-ballast fixtures I want to keep?

Yes, the 9.5" x 1.7" x 1.2" case fits standard T8 fixture channels, and the instant-start, multi-voltage design replaces older magnetic ballasts on 120 V or 277 V circuits.
