QT-2X40-277-DL OSRAM Sylvania Fluorescent Ballast

The OSRAM QT-2x40-277-DL and Sylvania QT2x40/277-DL are interchangeable fluorescent ballasts designed for use with two 40W, T12, F40T12/CW/DO/B fluorescent lamps. The ballast is specifically engineered to operate at a voltage of 277 Volts, making it suitable for use in commercial and industrial applications.

This OSRAM ballast is housed in a compact, yet robust DL design, providing excellent reliability and durability. It features a universal mounting system that simplifies installation in a variety of humidity and ambient temperature conditions.

The QT-2x40-277-DL/Sylvania QT2x40/277-DL is a digital, pulsed waveform ballast. Compared to traditional magnetic ballasts, digital ballasts offer increased energy efficiency, longer lamp life, and improved electrical performance. By utilizing pulse start technology, the ballast ensures consistent lamp ignition and stabilizes lamp operation, resulting in higher lumen output and superior color consistency.

Adjustable features include the ability to dim the lamps 1-100%, and an overvoltage protection function that prevents damage to the lamp during power surges. A mineral oil-filled construction provides excellent heat dissipation, ensuring steady operating temperatures that contribute to consistent light quality and extended lamp life.

Notable energy savings are achieved by the ballast's electronic design, which maintains the lamps at a near-optimal operating burning point while consuming less energy compared to magnetic ballasts. The QT-2x40-277-DL also complies with major energy efficiency standards, including Energy Star and DOE DLC Integrated Ballast Design, further reducing operational costs over the long term.

With the OSRAM QT-2x40-277-DL or Sylvania QT2x40/277-DL fluorescent ballast, businesses and organizations can upgrade their lighting systems to more energy-efficient, reliable, and cost-effective solutions, ideal for reduced energy consumption and budget-conscious environments.
