If you're dealing with flickering, humming, or dim T8 fluorescent lights, swapping out the ballast is usually the fix.

This GE UltraMax electronic ballast (model GE232MAX-N/ULTRA) is a solid, energy-efficient choice.

It runs on 120 to 277 volts, so it's versatile for residential, commercial, or industrial setups.

It's an instant-start ballast that handles one or two F32T8 lamps.

The active current regulation keeps each lamp's output independent – so if one lamp fails, the other stays on (parallel operation – super convenient).

It also has anti-striation circuitry to prevent that annoying spiraling effect.

Sound rating is Class A (20-24 decibels) – basically whisper-quiet.

The ballast factor is .87, which gives you nearly full light output while saving energy.

Mounting dimensions are 8.9 x 1.1 inches with slots 0.3 inches apart, so it fits standard fixtures.

It's also thermally protected and has auto-restart.

Rated for cold starts down to -20°F, and meets UL, CUL, NEMA, and RoHS standards.
