Electronic ballast Osram QTP-OPTIMAL 1X54…58, 198–264V AC, 50/60Hz, lifetime 100000 h, -20–50°C, 30×280×21 mm

Osram QTP-OPTIMAL 1X54…58 is an electronic ballast developed for single-lamp fluorescent fixtures operating from an AC supply of 198–264 V at 50/60 Hz. With a rated lifetime of 100,000 hours and an operating temperature range from -20 °C to 50 °C, this compact ballast (30 × 280 × 21 mm) is intended for both retrofit projects and new lighting installations where stable lamp starting and long service life are required.

Advantages

The electronic design ensures reliable ignition and stable current control for 54–58 W fluorescent lamps while reducing flicker and audible noise compared with older magnetic ballasts. The wide input voltage range and dual-frequency support make it suitable for varied supply conditions. Its long rated lifetime and robust temperature tolerance reduce maintenance frequency and support continuous operation in moderate environmental conditions. The compact form factor allows installation in tight fixture housings and simplifies replacements.

Suitable for

• Replacement of conventional magnetic ballasts in fluorescent luminaires
• New installations requiring compact electronic control for 54–58 W fluorescent lamps
• Commercial and industrial spaces with stable supply voltages within 198–264 V
• Applications where long lifetime and reduced maintenance are priorities

How to use

Install the ballast according to the luminaire manufacturer’s instructions and applicable electrical codes. Ensure power is disconnected before beginning work. Connect the mains conductors to the ballast input terminals and the lamp leads to the output terminals following the wiring diagram provided with the fixture. After wiring, restore power and verify correct lamp start-up and stable operation. Periodic visual inspection is recommended to check for secure connections and absence of overheating.

Usage recommendations

Use this ballast in fixtures designed for single 54–58 W fluorescent lamps and maintain ambient temperatures within the specified range. Avoid installation in locations with excessive moisture or dust without appropriate enclosure protection. For optimal lifetime, ensure proper ventilation around the ballast and follow local wiring regulations and safety standards during installation.
