Osram QTP-OPTIMAL 2x54-58 Electronic Ballast for T5 Lamps, 100,000h Lifetime, 198-264V

The Osram QTP-OPTIMAL 2x54-58 is a high-performance electronic ballast designed for operating two T5 fluorescent lamps (HE/HO) with wattages of 54W or 58W. Engineered for reliability and energy efficiency, this ballast delivers a long operational lifetime of up to 100,000 hours at a case temperature of 50°C, making it ideal for demanding commercial and industrial lighting applications. With a wide input voltage range of 198-264 V AC and a power factor greater than 0.95, it ensures stable performance and compliance with modern energy standards.

Advantages

This electronic ballast offers significant advantages over conventional magnetic ballasts, including higher energy efficiency (EEI A2), reduced total harmonic distortion (<10%), and automatic safety shutdown for enhanced protection. Its warm start method extends lamp life, while the compact metal housing allows for independent mounting or integration into luminaires. The ballast is also designed for low noise and flicker-free operation, contributing to improved lighting comfort.
