SYLVANIA FO40/830/ECO | Octron® 800 Series 40W 3000K 5-Foot T8 Fluorescent Lamp

The Sylvania Octron® 800 Series FO40/830/ECO (22138) is a commercial-grade, high-efficacy **40W linear fluorescent lamp** engineered for high-lumen structural downlighting and expansive architectural fixtures. Featuring a standard **G13 Medium Bi-Pin base** and a specialized **5-foot extended profile (59.61-inch MOL)**, this premium T8 tube outputs a robust lumen package in an inviting **3000K Soft White** color appearance. Utilizing advanced rare-earth tri-phosphor coatings to achieve an elite **85 CRI** color rendering accuracy baseline, it offers an exceptional **24,000 to 42,000-hour rated lifespan** depending on ballast configuration. Outfitted with Sylvania's signature **ECOLOGIC®** rating, this eco-conscious lamp passes federal TCLP standards, making it an ideal choice for smart buildings, commercial offices, and institutional environments.

Advanced Tri-Phosphor Engineering and Flexible Ballast Architecture

Sylvania Octron® 800 Series lamps provide premium lumen maintenance and color stability across extended service intervals. Operating seamlessly on high-efficiency electronic instant-start, rapid-start, or programmed rapid-start ballasts specifically designed for T8 layouts, this 5-foot lamp adapts effortlessly to dynamic commercial power grids. It is also backward compatible with legacy magnetic rapid-start ballasts rated for 265 mA T8 operation. Featuring an elite tri-phosphor blend, it retains exceptional color fidelity over time, preventing the muddy color shifts common in low-grade alternative lamps.

• Extended 5-Foot Architectural Footprint: Designed for specialized 60-inch commercial bays and industrial display retrofits requiring long, continuous lines of glare-free light.
• Superior Maintenance Lifecycle: Achieves a rated lifespan reaching up to 42,000 hours on programmed rapid start ballasts (at 12 hours per start), lowering corporate facility upkeep costs.
• ECOLOGIC® Environmental Safety: Built using a low-mercury composition that passes the federal Toxicity Characteristic Leaching Procedure (TCLP) test criteria.
• High-Efficiency Visual Clarity: Boasts a premium 85 CRI rating that reveals rich wood finishes, fabrics, and paint textures with crisp, natural accuracy.

System Integration & Ballast Wiring Guidelines

• Instant-Start Socket Requirements: When interfacing this T8 tube with high-frequency electronic instant-start ballasts, ensure both contacts of each shunted bi-pin lampholder socket are bridged and wired cleanly in strict adherence to National Electrical Code (NEC) standards.
• SUPERSAVER® & Energy Saving Constraints: For systems running energy-saving configurations, always deploy F32T8 ballasts delivering an open-circuit voltage profile of ≥550V RMS. Do not integrate into remote setups measuring below 550V, rapid-start lines below 570V, low power factor ballasts, air-handling fixtures, or unapproved inverter-based emergency backup battery networks. Failure to comply may generate severe arc-striking or operational instabilities.
• Cold Environment Operation: The minimum starting threshold is dictated entirely by the underlying ballast engineering. Note that if operating environments drop below 60°F (or below 70°F for equivalent 25W low-wattage lines), temporary visual lamp striation (swirling) or minor brightness decay may occur. This is a normal physical property and stabilizes once ambient heat levels normalize.
• Burning Cycle Longevity: Stated lifespans are verified using standardized 3-hour switching routines. Running the system on extended 12-hour continuous cycles yields a substantial increase in total overall hours of lamp life.

Recommended Commercial Applications

• Specialized Commercial Showcases: Ideal for 5-foot custom retail displays, automotive parts departments, and garment layout counters requiring vibrant, shadowless tri-phosphor light.
• High-Bay & Valance Fixtures: Perfect for corporate office architectural coves, library stack rooms, and institutional corridors using non-standard layout geometries.
• Industrial Workspace Task Lighting: Provides dependable, high-contrast soft white illumination above manufacturing assembly lines, quality inspection tables, and distribution center packing docks.
