SYLVANIA POWERSENSE | 4-Lamp F32T8 | 120-277V Dimming Electronic Ballast

The Sylvania Quicktronic Powersense 50738 (QHE 4x32T8/UNV DIM-TCL) is a high-efficiency dimming electronic ballast designed for maximum energy savings and lighting control flexibility. This 4-lamp F32T8 system allows for seamless dimming from 100% down to 5%, making it ideal for sustainability-focused projects, offices, and educational facilities. Featuring dual-voltage 120-277V capability and a small-can enclosure, it is engineered for easy integration into existing fixtures. With Lamp Striation Control (LSC), it minimizes or eliminates the flickering often seen in dimmed T8 energy-saving lamps, ensuring a smooth and professional light output.

Advanced Energy Savings

The Quicktronic 50738 delivers between 30% and 60% energy savings when compared to traditional magnetic F34T12 systems. By utilizing the POWERSENSE® dimming technology, facilities can further reduce energy consumption by tailoring light levels to occupancy and daylight availability. This ballast is NEMA Premium rated, qualifying for various utility rebates and meeting the most stringent green building energy codes. Its Parallel Circuitry ensures that if one lamp fails, the remaining lamps stay illuminated, minimizing maintenance urgency.

• LSC Technology: Minimizes lamp striations (swirling) common in energy-saving T8 lamps at low light levels.
• Small Can Design: Compact dimensions (9.47" L) allow for easy installation in narrow troffers and strips.
• Type CC Rating: Complies with UL935 requirements for commercial and industrial reliability.
• Extended Mounting: Supports remote mounting up to 20 feet from the lamps.
