SYLVANIA FO32/750/U6 | Octron® 700 Series 32W 5000K Daylight U-Bend T8 Fluorescent Lamp

The Sylvania Octron® 700 Series FO32/750/U6 (22064) is a commercial-grade, high-performance **32W linear U-bend fluorescent lamp** engineered for compact square troffers, localized recessed spaces, and architectural modular layouts. Featuring a standard **G13 Medium Bi-Pin base** and a precision **6-inch leg spacing footprint**, this premium **Curvalume®** formatted tube delivers a crisp, stimulating **5000K Daylight** color temperature. Utilizing specialized rare-earth phosphors to maintain a **75 CRI** color accuracy profile, it outputs **2,625 initial lumens** with an exceptional **15,000 to 28,000-hour rated lifespan** depending on the specific burning cycle and ballast design. This energy-efficient, bent-tube configuration provides outstanding lumen maintenance and systemic reliability, making it ideal for institutional grids, medical suites, and modern office spaces.

Space-Saving Curvalume® Engineering and High-Frequency Control Flexibility

Sylvania Octron® Curvalume® U-bend lamps are ideal for standard 2x2 ceiling troffers, packing the punch of a full-length linear tube into a compact, space-saving layout. Designed to operate safely on high-frequency electronic ballasts—including instant-start, rapid-start, or programmed rapid-start types engineered specifically for T8 modules—this versatile lamp easily integrates into legacy facilities or newly constructed building networks. Alternatively, it runs on traditional magnetic rapid-start ballasts built for 265 mA T8 lamp profiles, offering robust performance over extended commercial service life loops.

• Compact 6-Inch Center-to-Center Spacing: Designed specifically for modern modular fixtures, distributing light cleanly and minimizing the shadow zones found with longer bulbs.
• Energizing 5000K Color Profile: Emits a cool, crisp daylight spectrum that promotes alertness, enhances visual contrast, and provides an active ambiance ideal for productivity.
• High Initial Output: Delivers a strong 2,625 initial lumens with reliable lumen maintenance that preserves up to **2,365 mean lumens** at the midpoint of lamp life.
• Extended Burn Lifespans: Built to provide up to 28,000 hours of average service life on optimized cycles, reducing maintenance overhead in active multi-fixture setups.

System Integration & Ballast Safety Guidelines

• Instant-Start Wiring Controls: When operating this U-bend lamp on electronic instant-start systems, make sure both wires or contacts of each individual socket are cleanly shunted (connected to each other). Wire them directly to the appropriate ballast leads using National Electrical Code (NEC) compliant methods. These lamps handle instant-start configurations smoothly with ballast factors ranging from a minimum of 0.71 to a maximum of 1.20 at nominal input voltages.
• SUPERSAVER® & Energy-Saving Rules: For energy-saving applications, always power lamps using F32T8 ballasts that supply a minimum open-circuit voltage profile of ≥550V RMS at the lamp base. Avoid using this lamp inside: (1) remote fixtures with open-circuit voltages below 550V, (2) rapid-start ballasts below 570V, (3) specialized air-handling units, (4) low power factor ballasts, or (5) unlisted inverter-driven emergency battery systems. Defying these constraints can result in striking failure, poor cathode heating, or permanent electrical incompatibility.
• Operating Duty Cycles: Stated catalog lifespans are derived from a standardized 3-hour switching cycle. Extending the duration of the operational burn cycle will yield a substantial increase in the overall average lifespan of the tube.
• Cold Environment Operational Warning: The minimum starting threshold is determined by the underlying ballast engineering. Note that if fixtures are exposed to strong cross-drafts or ambient temperatures fall below 60°F (or below 70°F for comparable 25W variants), visual lamp striation (a rhythmic pulsing pattern running down the bent tube) or severe brightness decay may occur. This is a temporary physical reaction that does not harm the lamp, and output will normalize once ambient conditions rise.

Recommended Commercial & Institutional Applications

• Modular 2x2 Office Troffers: Perfect for corporate office drop-ceilings and recessed modular fixtures requiring bright, balanced daylight illumination.
• Institutional Corridor Lighting: Highly suited for schools, hospital wings, and public municipal corridors using compact square downlight layouts.
• Commercial Task Environments: Ideal for printing rooms, design studios, and laboratory workspaces requiring sharp visual contrast and high-color alertness.
