Ledvance Osram DULUX 18 W 2G11 Warm White is a compact fluorescent lamp designed for general indoor lighting. With a power consumption of 18 W and a warm white output of approximately 1200 lumens, this lamp provides consistent, energy-efficient illumination suitable for offices, corridors, retail fixtures and task lighting. The lamp offers a colour rendering index (CRI) of 80 and a rated lifetime of up to 12,000 hours, making it a practical choice where stable warm light and reduced maintenance frequency are desired.

Advantages

This compact fluorescent bulb delivers an efficient balance between light output and energy use, producing around 1200 lm while consuming 18 W. The warm white colour temperature and CRI 80 provide natural-looking illumination appropriate for many indoor environments. With an expected lifetime of up to 12,000 hours, the lamp reduces replacement intervals compared with shorter-lived light sources. The 2G11 base ensures compatibility with fixtures designed for this socket type and helps maintain a secure electrical and mechanical connection.

Suitable for

• General office lighting and workspaces
• Corridors, stairwells and common areas
• Retail display fixtures and shelving illumination
• Task lighting in workshops, reception areas and service counters

When it may not be suitable

This lamp is not intended for outdoor use or for fixtures without a compatible 2G11 socket. It is not suitable where precise colour matching or very high colour rendering is required, as CRI 80 provides good but not professional-grade colour accuracy. The lamp requires a ballast or driver compatible with compact fluorescent technology, so it may not work in fixtures designed exclusively for LED drivers without modification.

Key specifications

• Rated power: 18 W
• Luminous flux: approximately 1200 lm
• Light colour: warm white
• Colour rendering index: 80 (CRI 80)
• Base type: 2G11
• Rated lifetime: up to 12,000 hours

How to use

Install the lamp into a compatible fixture with a 2G11 socket and ensure any required ballast for compact fluorescent lamps is present and functional. Switch power off before replacing the lamp. After installation, allow a short warm-up period for the lamp to reach its full luminous output. For best performance, use the lamp in dry indoor environments and avoid repeated rapid on/off switching, which can shorten operational life.

What to consider before purchase

• Verify fixture compatibility with a 2G11 base and a ballast suitable for compact fluorescent lamps
• Confirm warm white light and CRI 80 meet your colour rendering needs
• Consider the rated lifetime of up to 12,000 hours relative to your maintenance schedule
• Ensure the lamp’s luminous flux (approx. 1200 lm) provides sufficient brightness for the intended area

Usage recommendations

For prolonged service life and consistent light output, install the lamp in well-ventilated indoor fixtures, avoid excessive vibration, and pair it with a compatible, correctly rated ballast. Replace in matching batches for uniform colour and brightness across multiple fixtures.
