The Sylvania CF5DSE827 (DULUX® S/E) is a commercial-grade, ultra-compact **5W single-tube compact fluorescent lamp (CFL)** designed for high-density public entry exit signage, step lighting modules, electronic task brackets, and localized hospitality wall sconces. Outfitted with a high-resistance **2GX7 4-pin plug-in base** and a sub-miniature **T4 glass profile**, this space-saving module is engineered specifically to operate via high-frequency electronic ballasts and architectural dimming systems. Utilizing rich rare-earth tri-phosphor compounds to achieve an **82 CRI** color rendering accuracy, it projects a soft, ambient **2700K Warm White** light field. Delivering **230 initial lumens** over a **10,000-hour rated average life**, this compact bulb is sold in bulk wholesale **cases of 50 units** to support corporate property maintenance retrofits and facility supply frameworks.

Advanced 4-Pin Base Controls and Sub-Miniature Thermal Dynamics

Sylvania DULUX® S/E single twin-tube lamps utilize a distinct sub-miniature physical blueprint to pack reliable gas-discharge capabilities into limited luminaire housings. Unlike standard 2-pin configurations that house an old-style mechanical starter element inside the base framework, the **4-pin 2GX7 plug-in layout** isolates the lamp’s internal cathodes. This distinct electrical pathing allows professional high-frequency electronic ballasts to precisely moderate the cathode pre-heating current prior to arc ignition. The results include a smoother, flicker-free start sequence, reduced end-of-life glass darkening, and seamless integration with localized architectural dimming grids or building automation systems.

• Electronic Ballast Compatibility: Engineered strictly to interface with electronic ballasts to eliminate strobing, maximize energy savings, and optimize system ballast factors.
• Bulk Facility Case Packaging: Shipped in commercial **cases of 50 pieces** to accommodate volume procurement requirements for property facility managers and electrical contractors.
• High Color Precision (82 CRI): Formulated with a select mix of rare-earth phosphors to project an authentic, warm **827 coding light field**, optimal for calming or retail accent areas.
• Miniaturized Form Factor: Measured at a tight **3.4 inches maximum overall length**, allowing this lamp to operate inside low-profile safety exit indicators and under-cabinet lines.

System Integration, Ballast Matching & Handling Safeguards

• Electronic Power Requirements Notice: This 4-pin sub-miniature CFL module cannot run directly off raw 120V or 277V facility power lines. It **requires an inline electronic fluorescent ballast** designed for 5W 4-pin configurations. Furthermore, it will not seat in regular 2-pin 2G7 or GX23 sockets; verify your fixture’s specific contact slots before completing replacement maintenance.
• End-of-Life (EOL) Protection Systems: To avoid excessive thermal strain, sub-miniature fluorescent grids should be linked to electronic ballast units equipped with **automatic EOL shut-off circuits**. This protection shuts down the terminal current if a cathode burns out, preventing structural distortion of the plastic 2GX7 base container.
• Glass Handling & Maintenance Protocols: Always turn off building electrical feeds at the main breaker board prior to changing out components or wiping lenses. Let the glass enclosure cool down completely for at least 10 minutes to minimize surface contact burns. Grip the element by its molded plastic base casing; **never twist or wrench on the small glass tubes directly**, as this can fracture the delicate seal lines.
• Responsible Recycling Compliance: This lamp contains trace measures of mercury vapor necessary for high-efficiency operation. Do not discard spent modules in common workplace rubbish piles. Ensure your maintenance team channels spent stock to professional municipal collection hubs or verified lighting reclamation companies. For details, consult **www.lamprecycle.org**.
