Overview
The GE-332-MAX-H/Ultra electronic ballast is a high-efficiency instant-start ballast designed for T8 fluorescent lamps in commercial and industrial lighting systems. This ballast provides immediate lamp ignition and maintains consistent light output across 2–3 lamp configurations, making it a reliable drop-in replacement for standard fluorescent fixtures used in warehouses, offices, and continuous-duty environments.
Key Features
- Instant-Start Technology: Immediate lamp ignition without warm-up delay, ideal for frequently accessed spaces and continuous-duty applications.
- Active Current Regulation: Individual lamp inverter modules regulate output to each lamp for consistent performance and extended lamp life.
- Anti-Striation Control: Delivers flicker-free, high-quality light output with no visible striations.
- Wide Input Voltage Range: Operates reliably at 120/277V AC (±10%), suitable for both standard and higher-voltage circuits.
- UL Type CC Rated: Provides arc-fault protection and meets rigorous safety standards for commercial applications.
- Cold-Start Capability: Minimum starting temperature of 0°F (−18°C), ensuring reliable operation in unheated spaces.
