Advantages

With a CRI of 80 it renders colors adequately for everyday tasks and living spaces. Its compact tubular design and G23 base simplify replacement in compatible fixtures, and the long rated lifetime reduces the frequency of bulb changes.

Suitable for

• General indoor lighting in homes and apartments
• Office and administrative spaces requiring warm white light
• Commercial fixtures such as reception areas, corridors, and display cabinets with G23 sockets
• Energy-conscious installations seeking lower power consumption

When it may not be suitable

This fluorescent lamp is not suitable for fixtures that require instant full brightness in critical timing applications, as compact fluorescent lamps typically have a short warm-up time. It is also not intended for use with dimmer switches unless the specific fixture and ballast are rated for dimmable CFLs.

Key specifications

• Rated power: 8.7 W (marketed as 9 W nominal)
• Luminous flux: ~600 lumens
• Color temperature / light appearance: warm white (designation 827)
• Color rendering index (CRI): 80
• Base type: G23
• Estimated lifetime: 10,000 hours

How to use

Install the lamp into a compatible G23 socket, ensuring the fixture is switched off and cool before replacement. After installation, switch on the power; the lamp will reach usable light output after a brief start-up period. Use the lamp with compatible electronic or magnetic ballasts as specified by the fixture manufacturer. Avoid handling the glass tube directly with bare hands for cleanliness and install in fixtures rated for compact fluorescent lamps.

What to consider before purchase

• Confirm the fixture uses a G23 base and is compatible with compact fluorescent lamps.
• Check whether the fixture requires a dimmable lamp or instant-start performance.
• Verify the desired color appearance: 827 indicates warm white light similar to traditional incandescent tones.
• Consider the rated lifetime and replacement frequency when comparing lamp types.

Usage recommendations

For best results, use this Osram DULUX S 9 W/827 in enclosed or open indoor fixtures designed for CFLs, and pair with compatible ballasts. Replace lamps in groups in larger spaces to maintain consistent color and brightness, and dispose of spent lamps according to local regulations for fluorescent lighting.
