With a Color Rendering Index (CRI) of 89, this energy-saving compact fluorescent lamp is designed for general indoor lighting where stable, long-lasting white light is required. The lamp is a stick-shaped compact fluorescent type suitable for fixtures that accept DULUX-style compact tubes.
The Osram DULUX 9 W lamp combines low power consumption with a relatively high luminous efficiency, yielding 660 lumens from 9 watts. Its cool white colour temperature ensures neutral, clear illumination appropriate for work and ambient environments. A CRI of 89 offers good colour rendering for tasks where distinguishing colours and details is important. The long rated service life of 20,000 hours reduces maintenance frequency compared with shorter-life lamps.
Install the Osram DULUX 9 W lamp in a compatible fixture that accepts compact fluorescent stick tubes, ensuring the lamp fits the socket type used by the luminaire. Switch off mains power before replacing lamps. After installation, operate the lamp on the fixture’s appropriate ballast or electronic control gear as required for compact fluorescent lamps. Allow a short warm-up period after switching on for the lamp to reach full light output.
Use this lamp in indoor environments within recommended ambient temperature ranges and in fixtures designed for compact fluorescent lamps. Avoid frequent on/off switching to maximize rated lifetime. Recycle or dispose of the lamp according to local regulations for lamps containing small amounts of mercury.
