Compact fluorescent lamp for general lighting

The SYLVANIA CF13DD/E/841/ECO is a 13 watt double-tube compact fluorescent lamp designed for general lighting applications. It uses a G24Q-1 4-pin base and delivers 900 lumens at a 3000K colour temperature. This lamp suits fixtures that accept 4-pin compact fluorescent bulbs.

Sustained output and rated life

Under continuous operation the lamp maintains its rated 900 lumen output for the duration of its 12000 hour rated life. The 13 watt power draw remains stable once the lamp reaches full brightness after a short warm-up period. Light output does not degrade rapidly during the rated lifespan.

G24Q-1 base and fixture compatibility

The G24Q-1 4-pin base limits use to ballasts and sockets specifically designed for this pin configuration. It cannot be used in screw-base or 2-pin fluorescent sockets without an appropriate adapter. The 3000K colour temperature is fixed and not adjustable.

Questions about this item

How much heat and power does the 13 watt fluorescent draw during all-day use?

The lamp consumes 13 watts and produces far less heat than an equivalent incandescent, making it suitable for continuous operation.

What fixture or ballast must I already have for the G24Q-1 4-pin base to work?

You need a compatible G24Q-1 4-pin socket with an electronic ballast designed for 13 watt compact fluorescent lamps.

Will the 3000K 900 lumen output match the older 20721 Dulux bulbs I am replacing?

Yes, this model is the 20721 Dulux with 3000K colour temperature and 900 lumens, so it matches the original specification.
