What this bulb delivers

The Ushio CF9D/827 is a 9 W compact fluorescent lamp that produces 525 lumens at a warm 2700 K colour temperature. Its double-tube design fits a two-pin base and carries a colour rendering index of 82 for natural indoor tones. Rated life reaches 10 000 hours, reducing replacement frequency in daily-use fixtures.

Where it fits and where it does not

Households wanting warm, efficient light for table lamps, wall sconces or ceiling pendants will find the output and colour suitable. Buyers who need a screw-in base, dimmable operation or instant full brightness should look at other technologies. The two-pin connector limits direct retrofit into standard Edison sockets without an adapter.

Deciding specification

The two-pin base type is the single detail that determines whether this lamp fits your fixture. Verify the socket before purchase; an incorrect base makes the bulb unusable regardless of wattage or colour quality.
