Product Overview

The GE232MAXPH UltraMax-H ballast is a high ballast factor (1.18) electronic ballast designed to deliver increased light output in T8 fluorescent systems.

This ballast is ideal for applications where maximum brightness is required, allowing fewer fixtures or lamps to achieve the same illumination levels.

Key Advantages

• Higher light output: Up to 15–20% more lumens vs standard ballasts
• Fewer fixtures required: Reduce installation cost
• Energy efficient: >90% efficiency with low THD
• Multi-voltage flexibility: 120-277V operation
• Parallel operation: Lamps stay lit if one fails

Applications

• Commercial office lighting retrofits
• Retail and showroom lighting
• Warehouses and industrial spaces
• Areas requiring higher illumination levels

Important Notes

• High Output Ballast: Produces more light than standard (0.87 BF)
• Instant Start: Best for continuous operation (not frequent switching)
• Not ideal for occupancy sensors due to reduced lamp life in switching applications
