SYLVANIA QHE3X32T8UNVISL | QUICKTRONIC® High-Efficiency 3-Lamp T8 Low Ballast Factor 120/277V Instant Start Electronic Ballast

The Sylvania QUICKTRONIC® QHE3X32T8UNVISL is a commercial-grade, high-efficiency **instant-start electronic ballast** engineered to drive two or three standard or energy-saving T8 linear fluorescent and U-bend lamps. Designed for dual-voltage **120V or 277V systems operating at 50/60Hz**, this high-performance component features a **low ballast factor of 0.78** to lower overall fixture power demand while maintaining uniform luminaire brightness. Outfitted with an integrated **Lamp Striation Control (LSC)** circuit layout, it effectively minimizes or eliminates the rhythmic pulsing patterns that commonly impact energy-saving fluorescent tubes. Housed in a durable **Small Can enclosure configuration**, this NEMA Premium certified ballast yields a **Total Harmonic Distortion (THD) under 10%**, making it an exceptional option for commercial offices, schools, and strict code-compliant energy modernization upgrades.

High-Efficiency Power Scaling and Striation Control Stability

Sylvania QUICKTRONIC® High Efficiency (QHE) ballasts optimize energy retention across commercial fluorescent grids by delivering 30% to 60% system energy reduction when compared to older legacy F34T12 magnetic components. Running with a **parallel wiring loop configuration**, this ballast ensures that if one lamp suffers an electrical failure or is physically broken, the remaining lamps continue to operate at full brightness. Its built-in **Lamp Striation Control (LSC)** system acts as an electronic filter, resolving unstable arc distributions often triggered inside energy-saving 25W and 28W T8 fluorescent modifications. Designed with a **Type CC rating** to counter component breakdown from sudden transient micro-arcs, this platform delivers dependable operation within strict sustainability projects.

• Low Ballast Factor Configuration (0.78): Formulated to optimize light levels for everyday workspaces, decreasing total energy draws while extending overall cathode lifespan.
• Parallel Circuit Wiring Layout: Isolates individual lamps within the multi-lamp array, enabling non-interrupted operational status across remaining functional tubes.
• NEMA Premium Qualification: Passes the highest structural thresholds for commercial rebate verification programs and qualifies corporate spaces for regional energy utility incentives.
• Remote Mounting Capabilities: Certified to support safe, isolated remote wiring extensions up to **20 feet** away from the active lampholders without lowering arc stability.

System Integration, Wiring Guidelines & Handling Protocols

• Mandatory Socket Shunting Requirements: Instant start electronic ballast networks require the use of **shunted lampholders (sockets)**. The internal socket wiring or duplicate side terminals must be interconnected (shorted) according to the case diagram before linking into the structural secondary ballast output wire leads. This ensures stable high-frequency current pathways to the cathodes.
• National Electrical Code Alignment: Ensure all wiring runs are permanently enclosed within a code-compliant electrical raceway or fixture gutter. The metal chassis of the ballast container **must be mechanically grounded** directly to the facility's equipment grounding conductor (green wire or bare conduit framework) to protect against unexpected ground faults and maintain clear FCC compliance.
• Thermal Environment Thresholds: This ballast maintains a native starting limit down to **-20°F (-29°C)** for standard T8 tubes. However, when paired with high-efficiency **SUPERSAVER® / Energy Saving (SS) lamps**, the minimum starting threshold shifts up to **60°F (16°C)**. Operating energy-saving lamps below this threshold may trigger hard-starting strain, early flickering, or premature cathode burn-out.
