OSRAM LUMILUX T2 FM | 13W/730 | W4.3 Subminiature Fluorescent

The Osram 13W/730 Lumilux FM is an ultra-slim, subminiature T2 fluorescent lamp designed for precision lighting in tight spaces. At just 7mm in diameter and 523.1mm in length, this lamp is a specialty solution commonly used in under-cabinet lighting, display cases, and atmospheric architectural accents. It delivers 930 lumens of warm 3000K light with a consistent tri-phosphor coating for reliable color rendering. Featuring a unique W4.3 x 8.5d axial base, it is engineered for use exclusively with electronic ballasts designed for subminiature technology, offering a long 10,000-hour rated life.

Product Overview

The Osram Lumilux FM (Fluorescent Miniature) range offers one of the slimmest profiles in the industry, allowing for "invisible" light sources in furniture and retail fixtures. The 13W version utilizes tri-phosphor technology to ensure that the light output remains stable and the color rendering (CRI 80+) stays accurate throughout the lamp's life. Its axial base design facilitates a sleek, continuous line of light when lamps are installed end-to-end. Because T2 lamps operate at higher surface temperatures than standard T8 or T5 tubes, they are optimized for electronic control gear (ECG) operation, which ensures safe starting and prevents overheating at the end of the lamp's life cycle.

• Extreme Slimness: 7mm tube diameter allows for revolutionary, low-profile luminaire designs.
• Optimized Efficiency: High luminous efficacy makes it a sustainable choice for long-run display lighting.
• Consistent Light: Lumilux phosphor technology provides a natural and pleasant 3000K warm white glow.
• Professional Grade: Rated for a 10,000-hour average lifespan with excellent lumen maintenance.
