What this bulb is and who it fits

The SYLVANIA 20683 Dulux is an 18 watt compact fluorescent lamp with a G24Q-2 four-pin base. It produces a warm 2700K light and carries a colour rendering index of 82. The double-tube design suits general lighting fixtures that accept this specific base type. Buyers whose fittings require a different pin arrangement or voltage will need another lamp.

The specification that decides compatibility

The G24Q-2 base is the single detail that determines whether this bulb fits. Only luminaires wired for a four-pin G24Q-2 socket can accept it; two-pin or other four-pin variants will not work. No adapter is included or implied.

Behaviour during continuous operation

Rated life is 12000 hours under normal switching cycles. The 18 watt draw remains steady once the lamp has started, and the 2700K colour temperature holds across that period. Frequent short cycles can reduce the achieved hours below the rated figure.

Questions about this item

How warm is the light from this 2700K fluorescent in a real fitting?

The 2700K colour temperature produces a warm white glow similar to a traditional incandescent, suitable for living rooms and bedrooms.

What does the G24Q-2 4-pin base limit when I install this lamp?

The G24Q-2 base only fits matching 4-pin sockets and requires a compatible electronic ballast; it will not work in 2-pin or screw-in holders.

What fixture depth or clearance does this double compact 18W tube need?

The double-tube design needs a housing deep enough for its overall length and the 4-pin connector; check your luminaire's maximum lamp length before fitting.
