Fluorescent-style LED tube Osram DULUX L55 HF V 25W 840 2G11, 3250 lm, 4000K

Osram DULUX L55 HF V 25W 840 2G11 is a retrofit LED tube designed to replace compact fluorescent lamps with a 2G11 base. With a rated power of 25 W and a nominal luminous flux of 3250 lm at a neutral white color temperature of 4000 K, this lamp provides steady, efficient illumination suitable for professional indoor environments. The product is intended for use in fixtures that accept 2G11 compact fluorescent tubes and delivers reduced power consumption and longer operating life compared with traditional fluorescent sources.

Advantages

The lamp combines low energy consumption with a high luminous output, offering consistent color rendering and minimal flicker. Its 2G11 retrofit form factor allows direct replacement in many existing luminaires without major rewiring. The neutral 4000 K color temperature ensures balanced, task-oriented lighting that supports visibility and visual comfort in workspaces. Maintenance intervals are extended due to the longer service life of LED technology and there is reduced heat emission compared with fluorescent equivalents.

Suitable for

• Office lighting and administrative spaces
• Retail aisles and display lighting
• Corridors, stairwells and common areas
• Workrooms, storerooms and technical facilities

Key specifications

• Rated power: 25 W
• Nominal luminous flux: 3250 lumens
• Correlated color temperature: 4000 K (neutral white)
• Base type: 2G11 (compact fluorescent retrofit form)
• Designed for use as a direct LED replacement for HF electronic ballast systems or compatible fixtures — check compatibility with the existing gear before installation
• Light distribution: omnidirectional/linear tube output suitable for fixtures designed for compact fluorescent tubes

How to use

Before installation, disconnect power to the luminaire. Verify that the fixture accepts a 2G11 retrofit LED tube and inspect the existing ballast or gear for compatibility; some installations may require bypassing or replacing the ballast according to the luminaire manufacturer’s guidance. Insert the LED tube into the 2G11 sockets, ensuring a secure mechanical fit, then restore power and verify correct operation and absence of flicker. Follow local electrical codes and safety procedures; if unsure, use a qualified electrician for installation.

Recommendations

For optimal performance, use this LED tube in dry indoor environments at ambient temperatures recommended by the luminaire manufacturer. Avoid frequent on/off switching to maximize lifetime, and ensure the luminaire provides adequate heat dissipation. When retrofitting, confirm ballast compatibility or perform ballast bypass to achieve the rated luminous output and lifetime.
