Sylvania 20879 26W Triple Tube Fluorescent

The Sylvania 20879 is a 26-watt compact fluorescent bulb with a GX24Q-3 four-pin base designed for general lighting fixtures. It produces a warm 2700K colour temperature suitable for residential and hospitality spaces. The transparent triple-tube design delivers 1800 lumens with a colour rendering index of 82. Buyers needing a different base type or higher lumen output should consider other options.

Capacity and rated life

Rated at 12000 hours, the bulb provides extended service life compared to standard incandescent alternatives while consuming 26 watts. The 1800-lumen output comfortably illuminates medium-sized rooms such as bedrooms or offices. It runs out of suitability for high-bay or task lighting requiring cooler colour temperatures or significantly higher brightness levels. The 82 CRI supports general ambient use but not colour-critical work.

GX24Q-3 base and ECO designation

The four-pin GX24Q-3 base ensures compatibility with matching electronic ballasts and prevents incorrect installation. The ECO designation indicates reduced mercury content for easier disposal compliance. No additional accessories or software are bundled with the bulb. Installers must verify ballast compatibility before use as the lamp requires a specific electronic ballast to operate correctly.

Questions about this item

Will this 26 W GX24Q-3 triple-tube lamp work in my existing magnetic-ballast fixture?

The GX24Q-3 base is designed for electronic ballasts only; a magnetic ballast will not start the lamp correctly and may damage it.

How can I verify the 2700 K colour temperature and 1800 lumen output once the bulb is installed?

A warm, incandescent-like glow and bright, even illumination across the room indicate the rated 2700 K and 1800 lm are being delivered.

Does the 20879 package include a ballast or starter, or must I supply them separately?

Only the 26 W triple-tube fluorescent bulb is included; the matching electronic ballast and any required starter must be purchased separately.
