SYLVANIA QHE2X32T8UNV-ISN-SC | QUICKTRONIC® High Efficiency 2-Lamp T8 Instant Start Ballast

The Sylvania QUICKTRONIC® High Efficiency QHE2X32T8UNV-ISN-SC (51398) is a commercial-grade, multi-voltage **electronic T8 ballast** engineered to optimize standard and energy-saving linear fluorescent systems. Operating on a flexible **120V to 277V** commercial line, this high-performance module drives one or two lamps with a **0.88 normal ballast factor** to sustain peak luminous efficacy across office grids, schools, and warehouse facilities. Featuring an advanced **Instant Start parallel circuit topology**, it ensures independent lamp operations, meaning if one bulb fails, the remaining unit continues to run seamlessly. Enclosed in a compact, **Small Can (SC) design**, this NEMA Premium certified engine reduces systemic power draw while integrating Lamp Striation Control (LSC) to stabilize modern energy-saving fluorescent tubes.

High-Efficiency Energy Retrofits and Advanced Striation Control

Sylvania QUICKTRONIC® QHE systems are built to maximize savings on energy bills. Upgrading legacy F34T12 magnetic systems with this unit slashes overall energy consumption by 30% to 60%, while offering up to a 6% efficiency increase over standard electronic ballasts. When paired with high-performance OCTRON® 800 XP® SUPERSAVER® lamps, it surpasses an incredible **100 lumens per watt (LPW)** system threshold. This model includes specialized **Lamp Striation Control (LSC)** circuitry, which minimizes or eliminates the rhythmic pulsing patterns and spiraling light waves common in eco-friendly 25W, 28W, and 30W T8 energy-saving tubes, providing crisp, flicker-free illumination.

• Parallel Independent Circuitry: Lamps wire independently of one another. If one lamp expires or breaks, the remaining fluorescent tube stays lit at full illumination, streamlining facility troubleshooting.
• Small Can (SC) Profile: Compact housing geometry fits smoothly into standard narrow wireway channels inside linear troffers and commercial strip fixtures.
• NEMA Premium Qualified: Certified to clear strict utility threshold benchmarks, making installations eligible for high-tier municipal energy efficiency rebate programs.
• Extended Remote Mounting Footprint: Supports flexible structural configurations, allowing remote mounting placement up to 20 feet away from the light fixture housing.
