Ballast for 347-volt T8 fixtures

This GE 74098 UltraMax electronic ballast operates at 347 volts and drives three or four F32T8 lamps. It is built for commercial fluorescent installations that require instant-start operation and a low-profile housing. The unit weighs little and fits tight mounting spaces with its 8.9-inch length and 1.1-inch width.

Anti-striation circuitry and auto-restart

The ballast includes anti-striation control that suppresses the spiraling effect sometimes seen in T8 lamps. Auto-restart and thermal protection functions are integrated, while a Class A sound rating of 20 to 24 decibels keeps audible noise low. A ballast factor of .77 reduces per-lamp wattage for energy savings, and efficiency exceeds 90 percent.

Mounting slots and lamp count before ordering

Verify that the mounting slots set 0.3 inch apart match the existing fixture holes. Confirm the supply voltage is 347 volts and that the fixture uses three or four F32T8 lamps, as the ballast does not support other quantities. The low ballast factor means light output per lamp is reduced, so ensure the lower lumen level meets the space requirements.

Questions about this item

When will the lamps driven by this 74098 ballast need replacement?

The instant-start design supports long lamp starting cycles, so F32T8 lamps typically last their rated life before needing change-out.

What thermal limit appears first during continuous operation?

Built-in thermal protection will shut the unit down if internal temperature exceeds safe levels before any other component reaches its limit.

How much audible noise does the 74098 produce in an all-day installation?

Sound rating is Class A at 20-24 decibels, so the ballast runs quietly even when powering lamps continuously.
