18 W G24d-2 fluorescent lamp

This 18 watt double-tube fluorescent bulb uses a G24d-2 two-pin base and produces warm white light at 3000 K. It is designed as a direct replacement for compatible downlights and recessed fixtures in residential or commercial settings.

Suits existing G24d-2 fixtures

The lamp fits fixtures wired for a G24d-2 base and rated for 18 W operation. Buyers whose luminaires require a different pin spacing, a four-pin electronic base, or a higher lumen output should look at alternative models.

Simple two-pin installation

Insert the pins straight into the socket until they seat firmly; no tools are required. The most common issue is forcing the bulb into a mismatched base, which bends the pins and prevents proper electrical contact.

Questions about this item

Does my fixture need a G24d-2 base and a ballast rated for 18 watts?

Yes, the bulb has a G24d-2 two-pin base and draws 18 watts, so the fixture must accept that base type and provide a compatible ballast.

Can I keep my existing G24d-2 ballast when swapping to this 3000 K tube?

The lamp is designed for G24d-2 magnetic ballasts, so an existing ballast of the same type and wattage will operate it correctly.

How can I verify the 3000 K warm white output after installation?

The light should appear warm white with a CRI of 82, matching the 3000 K rating printed on the tube.
