SYLVANIA CF18TEIN841ECO | DULUX® T/E 18W 4100K Triple-Tube Compact Fluorescent Lamp

The Sylvania CF18TEIN841ECO (DULUX® T/E) is an industrial-grade, energy-efficient **18W triple-tube compact fluorescent lamp (CFL)** engineered for commercial recessed downlights, shallow office troffers, hospitality corridors, and surface-mount architectural fixtures. Outfitted with a specialized **GX24q-2 4-pin plug-in base** and a high-density **T4 triple-tube geometry**, this compact module projects an even, glare-free distribution of light. Utilizing high-purity internal rare-earth phosphors to achieve an **82 CRI** color accuracy baseline, it projects a crisp **4100K Cool White** light spectrum. Delivering **1,164 initial lumens** over an extended **12,000-hour rated service life**, this eco-conscious lamp features ECOLOGIC® construction to meet strict hazardous waste guidelines, serving as a high-performance replacement bulb across corporate and institutional networks.

Triple-Tube Lumen Density and Sustainable ECOLOGIC® Engineering

Sylvania DULUX® T/E compact fluorescent lamps feature an optimized multi-tube configuration that concentrates high lumen density into an exceptionally compact physical footprint. The triple-tube arrangement increases surface area within a shortened frame, optimizing thermal performance and enabling peak light output when operated at **35°C (95°F)** in a base-up orientation. Engineered with a reliable **12,000-hour rated lifespan**, this bulb maintains a high-efficiency curve, preserving **1,001 mean lumens** at mid-life. As an **ECOLOGIC® certified product**, it passes the EPA’s Toxicity Characteristic Leaching Procedure (TCLP) test criteria for classification as non-hazardous waste in most states, simplifying building disposal protocols and reducing environmental impact during large-scale retrofits.

• High-Frequency Dimming Capabilities: Features a 4-pin base wiring layout that supports direct integration with electronic dimming ballasts, facilitating advanced building energy management systems.
• Excellent Lumen Maintenance: Formulated with a specialized premium internal glass wash that resists phosphor degradation, maintaining consistent, flicker-free light over time.
• Compact Form Factor: Shortened **4.4-inch maximum overall length (MOL)** allows clean installation within modern, shallow architectural low-profile commercial downlight cans.
• Extended Lifespan Scaling: Rated life metrics are established on standard 3-hour operating cycles; running the lamp on longer, continuous corporate shifts yields a substantial lifetime increase.

System Integration, Ballast Matching & Safety Protocols

• Electronic Ballast Compatibility Requirements: This 4-pin plug-in lamp operates strictly via compatible high-frequency electronic ballasts. It cannot interface directly with raw line voltage (120V/277V) or older magnetic pin-base ballasts. Minimum starting temperature is a distinct property of the coupled ballast engine; always verify thermal parameters with the ballast manufacturer before uninsulated exterior deployment.
• End-of-Life (EOL) Protection Safeguards: Because compact T2, T4, and T5 fluorescent tubes operating on high-frequency electronic circuits can occasionally encounter normal structural end-of-life strain—such as local cathode overheating or glass hairline cracks—NEMA strongly recommends installing this lamp exclusively in fixtures equipped with an automatic **electronic ballast EOL shutdown circuit**.
• Sustainable Disposal Protocol: While built to fulfill TCLP thresholds, these lamps contain trace amounts of mercury vapor common to all fluorescent systems. Do not crush or throw directly into generic community waste bins. For safe local commercial disposal recycling points, consult state environmental rules or visit **www.lamprecycle.org**.

Recommended Professional & Commercial Applications

• Commercial Downlights & Atriums: Perfect for recessed architectural ceiling cans inside office entrance halls, elevator lobbies, and institutional common spaces.
• Corporate Office Corridors: Well-suited for shallow multi-tube commercial troffers, general utility walkways, and reception areas requiring bright, cool white light.
• Public Space Surface Mounts: Ideal for public facilities, school buildings, transit stations, and hospitality corridors where low-maintenance, long-term illumination is required.
