Buyers whose fixtures require a different base type or higher output should look elsewhere. Dimmable operation is not supported by this model. Spaces needing cooler colour temperatures or instant full brightness from cold start are not a match.

Single tube 2-pin shape

The compact dimensions allow installation in shallow recessed cans or decorative glass shades where longer tubes would not fit. No additional starter or ballast is included; the fixture must provide the correct G23 circuit.

Questions about this item

Do I need a fixture that accepts a G23 two-pin base for this Ushio CF7S/827 bulb?

Yes, the bulb uses a G23 single-tube two-pin base, so the socket must match that exact base type.

Will this 7 W fluorescent bulb run on an older magnetic ballast designed for higher-wattage tubes?

It requires a ballast rated for a 7 W compact fluorescent lamp; an older magnetic ballast for larger tubes may not start it correctly.

How can I confirm the bulb is performing as specified after installation?

Check that it lights instantly, shows a warm 2700 K colour and delivers roughly 400 lumens; the rated life is 10000 hours.
