SYLVANIA QHE 2x86T8HO/UNV-PSH-HT | Quicktronic High Efficiency T8HO Ballast

The Sylvania Quicktronic High Efficiency (QHE) 2x86T8HO/UNV-PSH-HT (50304-4) is a professional-grade **Programmed Rapid Start electronic ballast** engineered for high-output (HO) T8 lighting systems. Designed to operate 1 or 2 F96T8HO lamps (as well as various F72, F60, and F48 HO T8 lengths), this ballast delivers a **0.96 Ballast Factor** for maximum light output. Utilizing **PROStart® technology**, it extends lamp life in frequent-switching applications, making it ideal for high-ceiling commercial and industrial spaces.

Performance and Reliability for High-Output Systems

This QHE ballast combines high-efficiency operation with the durability required for T8HO applications. By meeting **NEMA Premium** standards, it ensures superior energy savings and qualifies for utility incentive programs. Its parallel circuitry ensures that even if one lamp fails, the other continues to operate, maintaining illumination and simplifying facility maintenance.

• PROStart® Technology: Programmed Rapid Start provides longer lamp life in applications involving frequent on/off cycling.
• Lamp Striation Control (LSC): Specifically engineered to prevent swirling light patterns in energy-saving T8 lamps.
• Versatile Application: Suitable for a wide range of T8HO lengths, providing flexibility for diverse lighting layouts.
• Reliable Starting: Certified for cold-weather starting down to -20°F (-29°C), making it suitable for outdoor and unheated environments.
