26W G24d-3 Compact Fluorescent Lamp

This SYLVANIA CF26DD/841/ECO is a 26-watt double-tube compact fluorescent lamp with a G24d-3 two-pin base. It delivers a cool white 4100K colour temperature and a colour rendering index of 82. The rated lifetime is 10000 hours. It is designed for magnetic ballast fixtures in commercial or residential settings.

Suits magnetic ballast fixtures needing 26W

This lamp fits luminaires that accept a G24d-3 base and operate a 26-watt double compact fluorescent tube on a magnetic ballast. It is not suitable for electronic ballast sockets, G24q four-pin bases, or fixtures requiring a different wattage or tube configuration. Buyers needing dimmable LED replacements or higher efficacy should consider other technologies.

G24d-3 two-pin base for magnetic ballasts

The G24d-3 two-pin base is the single specification that determines compatibility. It only works with magnetic ballasts wired for this exact base type. Verify the fixture ballast and socket before purchase.

Questions about this item

Will the G24d-3 base fit the magnetic ballast in my existing downlight fixture?

Yes, the G24d-3 base is designed for magnetic ballasts and will fit compatible 2-pin sockets in existing downlights or recessed cans.

How can I verify the 4100K cool white output is correct once installed?

The lamp should emit a neutral cool white light with a CRI of 82; compare the colour appearance to a known 4100K source or use a handheld colour meter for confirmation.

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

The package contains only the 26W double-tube CFL bulb (model 21115); magnetic ballasts and any required starters are not included and must be purchased separately if the fixture lacks them.
