Compact fluorescent lamp for general lighting

The Ushio CF13S/827 is a 13W single-tube fluorescent bulb with a GX23 2-pin base. It produces 800 lumens at a warm 2700K colour temperature and has a rated life of 10000 hours. The lamp measures 7.08 inches in overall length and 0.50 inches in diameter. It suits fixtures designed for this specific base and wattage.

Suits users replacing a matching GX23 lamp

This bulb fits existing fittings that accept a GX23 2-pin single-tube format at 13W. It is not for buyers who need a different base type, a higher or lower wattage, or a non-fluorescent technology such as LED. Shoppers requiring a dimmable source or a different colour temperature should look at other options.

GX23 2-pin base determines compatibility

The single specification that decides fit is the GX23 2-pin base. Only fixtures wired for this exact base will accept the lamp. Verify the fixture marking before purchase to ensure electrical and mechanical compatibility.

Questions about this item

Does the 13 W power draw stay constant as the lamp ages?

The lamp is rated at 13 W and 800 lumens; power consumption remains at the rated wattage throughout its 10 000-hour life.

How much heat does the 13 W CF13S/827 produce during continuous operation?

At 13 W the bulb converts most input power to light, so surface heat is modest compared with an equivalent incandescent, but the fixture must still allow normal air circulation around the 7.08-inch tube.

Will this GX23 2-pin base fit my existing fixture?

The bulb uses a GX23 two-pin base; it only works in sockets designed for that exact base type.
