Product Overview

The GE 71497 GE632MAX-H90-S60 UltraMax is a 6-lamp F40T8 step-dimming ballast combining high ballast factor output (1.18) with bi-level switching capability — allowing luminaires to operate at full output (100%) or switch down to 60% for occupancy-based or daylight-harvesting energy management without continuous dimming controls. The 100%/60% step dimming is controlled via the gray wire switching the ballast between high and low output states.

At 95% electrical efficiency and 1.18 ballast factor across 6 lamps, this ballast maximizes lumen delivery per watt — suited for high-ceiling commercial and industrial environments where maximum light output and bi-level control are both required. Parallel lamp wiring keeps remaining lamps operating if one fails. Anti-striation control eliminates visible lamp swirling. UL Type HL listing and UL 55C ambient rating confirm suitability for high-temperature fixture and commercial applications. Remote mounting up to 6 feet allows ballast placement away from the lamp for thermally demanding installations.

Compatible Applications

High-output 6-lamp F40T8 commercial fluorescent fixtures — Warehouses, industrial facilities, gymnasiums, and retail spaces requiring bi-level switching and maximum lumen output.
Occupancy sensor and bi-level switching applications — Step dimming (100%/60%) for energy code compliance and occupancy-based light level reduction.
High-temperature fixture installations — UL 55C high-temperature ambient rating and inherent thermal protection for elevated-temperature applications.
Outdoor and low-temperature installations — UL Type 1 Outdoor rated; -20°F cold start for covered exterior and unheated space applications.

Before Ordering — Verify

Lamp Type: Confirm your lamps are F40T8.
Lamp Count: This is a 6-lamp ballast. Confirm your fixture requires exactly 6 lamps.
Input Voltage: Confirm your circuit is 120V. This is not a universal voltage ballast — confirm voltage before ordering.
Dimming Type: This is a bi-level step-dimming ballast (100%/60%) — not a continuous 0-10V or DALI dimming ballast. Confirm your control system uses switching-based bi-level control.
Ballast Factor: The 1.18 high BF increases system wattage. Confirm high output is appropriate for your application.
Physical Fit: Confirm 11.8" x 1.7" x 1.2" fits within your fixture's ballast cavity.
