SYLVANIA LUMILUX FM | 13W/830 | T2 Subminiature Fluorescent

The Sylvania 21644 (FM13/830) is an ultra-slim, designer-series subminiature T2 fluorescent lamp engineered for high-performance lighting in extremely tight spaces. Measuring only 7mm in diameter and 20.60 inches (523mm) in length, this lamp is a specialized solution for ultra-low-profile fixtures that "disappear" into their environment. Delivering 930 lumens of warm 3000K light, it utilizes advanced tri-phosphor technology to provide superior color rendering (80 CRI) and exceptional 90% lumen maintenance over its 10,000-hour rated life. Featuring a single-pin axial base, it ensures a secure electrical connection in specialized showcase and task lighting luminaires.

Product Overview

The Sylvania FM13/830 belongs to a class of subminiature lamps that outperform traditional T5 preheat lamps in both efficacy and form factor. Its incredibly small 7mm diameter allows lighting designers to create lightweight, minimalist fixtures for retail displays, furniture task lights, and architectural coves. The 3000K Warm White output is specifically tuned to blend seamlessly with existing halogen or incandescent systems, while the high 80 CRI ensures that illuminated merchandise or surfaces appear vibrant and accurate. Optimized for use with Quicktronic FM electronic ballasts, this lamp provides flicker-free operation and reliable starting even in cold-start scenarios.

• Ultra-Slim Design: T2 (2/8") diameter is roughly 50% thinner than standard T5 tubes.
• High-End Phosphors: Tri-phosphor coating provides a high-quality spectrum for professional color accuracy.
• Long Life: 10,000-hour average life reduces maintenance costs in difficult-to-reach installations.
• Positive Retention: The axial base design provides a firm click-in fit to prevent vibration-related displacement.
