Product Overview

The GE 73190 UltraMax-H is a high ballast factor (1.18) electronic ballast designed to deliver maximum light output in T8 fluorescent systems.

This ballast increases lumen output by approximately 15–20% compared to standard ballasts, making it ideal for high-ceiling or high-brightness applications.

Key Advantages

• Maximum brightness: Higher lumen output with fewer fixtures
• Fixture reduction strategy: Achieve same light with fewer lamps
• Multi-voltage flexibility: 120–277V
• Parallel operation: Lamps remain lit if one fails
• Reliable performance: Designed for demanding applications

Applications

• Warehouses and industrial spaces
• High ceiling commercial areas
• Retail environments needing higher brightness
• Retrofit projects reducing fixture count

Important Notes

• High Output Ballast: Produces ~15–20% more light than standard (0.87 BF)
• Higher energy consumption vs standard ballast
• Instant Start: Best for continuous operation
• Not recommended for occupancy sensors (use programmed start instead)
