OSRAM DULUX® L | 55W/830 | 535mm 2G11 Lumilux Warm White Compact Fluorescent Lamp

The Osram Dulux L 55W/830 is a high-output, single-ended 4-pin compact fluorescent lamp designed for professional lighting in retail, office, and industrial environments. Delivering a powerful 4800 lumens, this 535mm (21.1") lamp provides the light output of traditional linear tubes in a significantly more compact form factor. Featuring Lumilux Warm White (3000K) technology, it offers excellent color rendering (CRI 80-89) and a long service life of up to 20,000 hours when used with electronic control gear. Its versatile 4-pin 2G11 base allows for operation on magnetic, electronic, or dimming ballasts, making it a flexible solution for high-quality architectural and commercial fixtures.

High-Performance Professional Lighting

The LUMILUX® L 55W/830 excels in applications where space is limited but high light levels are required. Often referred to as a "Long Twin Tube," it is approximately half the length of a standard 4ft fluorescent lamp while providing comparable brightness. This lamp is fully dimmable when paired with appropriate DALI or 1-10V dimming ballasts, offering energy savings and atmospheric control. Its consistent light output and superior color fidelity make it ideal for department stores, schools, and modern office layouts.
