GE 72266 UltraMax Electronic Fluorescent T8 Ballast (10-Pack)

The GE 72266 UltraMax Electronic Fluorescent T8 Ballast is designed to be a versatile, drop-in solution for powering standard F32T8 linear fluorescent lamps. Each ballast accepts input voltages ranging from 120 to 277 volts, which means a single SKU works across residential, commercial, and light-industrial electrical systems. The instant start design brings lamps to full brightness immediately without the warm-up flicker associated with older magnetic ballasts, and the built-in anti-striation circuitry addresses the spiraling light pattern that can be a visual nuisance in fluorescent installations.

Sold in a convenient ten-pack, this ballast is well suited for facility managers, electricians, and contractors who need to retrofit or maintain multiple fixtures efficiently. Active current regulation independently manages the output to each lamp, so performance remains stable whether one or two F32T8 tubes are installed. The compact 9-inch by 0.9-inch footprint fits comfortably inside standard T8 troffer housings, and the closely spaced mounting slots provide secure attachment. For large-scale relighting projects where reliability and multi-volt flexibility are priorities, the GE UltraMax series remains a proven workhorse.
