Product Overview

The Sylvania QHE 3x32T8/UNV ISM-SC is a high‑performance electronic ballast designed for 2‑3 T8 fluorescent lamps (25W–32W). With a medium ballast factor of 0.98, it delivers near‑normal light output while providing energy savings – ideal for commercial, industrial, and institutional applications where standard illumination levels are required. The ballast features programmed rapid start (PROStart) technology, which preheats cathodes before ignition to extend lamp life in frequently switched fixtures.

Operating on dual voltage 120‑277V, this ballast meets NEMA Premium requirements and qualifies for utility incentives. Its parallel circuit design ensures that if one lamp fails, the remaining lamps continue to operate. The ballast is Type 1 Outdoor rated and built in a compact small can enclosure (9.47″L x 1.69″W x 1.18″H) for easy installation in tight fixture spaces. Lamp striation control (LSC) minimizes or eliminates striations common in T8 energy‑saving lamps.

Why Choose This Product

• Medium ballast factor 0.98 – balanced light output and energy savings: Ideal for offices, schools, and retail where standard illumination levels are sufficient.
• Programmed rapid start: Extends lamp life in areas with frequent switching (e.g., restrooms, hallways, classrooms).
• Energy savings: Delivers 30‑60% energy savings compared to F34T12 magnetically ballasted systems; up to 6% (2‑5W) savings over standard electronic ballasts.
• Wide lamp compatibility: Supports 2‑3 energy‑saving and standard T8 lamps, plus U‑bend and 60″ FO40 lamps – reduces inventory complexity.
• Type 1 Outdoor rating: Suitable for damp/wet locations when installed in approved weatherproof fixtures.
• NEMA Premium compliant: Qualifies for utility incentives and meets the most stringent energy codes.
• Class A sound rating: Silent operation for noise‑sensitive environments.
• Lamp striation control (LSC): Eliminates unsightly striations in T8 energy‑saving lamps.
