What this bulb is and who it suits

The Ushio CF13DE/841 is a 13 watt dimmable compact fluorescent lamp with a G24q-1 four-pin base. It produces 900 lumens at a 4100K colour temperature and has a rated life of 10000 hours with a CRI of 82. It is intended for commercial or residential fixtures that use electronic dimming ballasts and replaces a 60 watt incandescent equivalent.

What to verify before ordering

Confirm that the existing fixture uses a G24q-1 four-pin socket designed for electronic ballasts. The lamp requires a compatible dimming ballast to operate and to enable dimming function; it will not work on magnetic ballasts or direct mains voltage. Check the ballast specifications match the 13 watt double-tube configuration.

How it fits into a lighting installation

The double-tube design fits standard recessed or surface-mounted luminaires accepting G24q-1 bases. Its 13 watt draw reduces circuit load compared to the 60 watt incandescent it replaces, freeing capacity on shared lighting circuits. The 4100K output suits task areas needing neutral white light, while the dimmable ballast allows adjustable levels without changing the fixture wiring.

Questions about this item

Does the CF13DE/841 arrive with a ballast or must I buy one separately?

The bulb has a G24q-1 4-pin base that plugs into a compatible electronic ballast; the ballast itself is not included.

How do I decide between the 841 and another colour code for this wattage?

The 841 code means 4100 K colour temperature and CRI 82; choose it when you need cool-white light with good colour rendering.

What does the 60 W equivalent claim mean for actual light output?

The lamp produces 900 lumens at 13 W, matching the brightness of a traditional 60 W incandescent while using far less power.
