Product Overview

The Sylvania QHE4X32T8UNV represents the pinnacle of high-frequency electronic ballast technology. By utilizing parallel circuitry, this ballast ensures that if one lamp fails, the remaining lamps stay illuminated, minimizing maintenance urgency. It features Lamp Striation Control (LSC), which eliminates the visible swirling or "snaking" effect sometimes seen in energy-saving T8 lamps. This NEMA Premium rated ballast is 6% more efficient than standard electronic ballasts, making it a primary choice for facilities seeking utility rebates and reduced operational costs.
