OSRAM LUMILUX | 23W/840 | T8 Cool White Fluorescent Tube (970mm)

The Osram L 23W/840 is a specialty-length T8 fluorescent tube designed for specific commercial fixtures requiring a 970mm (approx. 38-inch) lamp. Featuring Lumilux tri-phosphor technology, this lamp delivers a bright 1,900 lumen output with a crisp 4000K Cool White color appearance. It is an ideal solution for modular furniture, kitchen cabinetry, and retail display cases where standard 3-foot or 4-foot lamps will not fit. With a high CRI of 80–89 and a rated service life of 20,000 hours on electronic gear, it ensures consistent, high-quality illumination and reduced maintenance cycles in professional environments.

Product Overview

The Osram 23W/840 T8 is a "special length" lamp often used in European-designed fixtures or specialized industrial machinery. While most T8 lamps follow 24", 36", or 48" standards, this 970mm tube fills a unique niche for mid-sized enclosures. Its Lumilux 840 phosphor coating provides a neutral, revitalizing white light that enhances productivity and visibility. This lamp is compatible with both conventional ballasts (with a starter) and high-frequency electronic ballasts. When paired with an Osram Quicktronic ballast, it benefits from an extended lamp life and improved energy efficiency, making it a reliable choice for both professional and high-end residential task lighting.

• High Lumen Maintenance: Advanced coating ensures the tube stays bright throughout its 20,000-hour rated life.
• G13 Medium Bi-Pin: Standard connection pins for easy installation in existing T8 sockets.
• Excellent Color Rendering: CRI of 80–89 ensures that objects appear natural and vibrant under the light.
• Universal Application: Perfect for supermarket displays, workshop lighting, and integrated furniture fixtures.
