What this bulb is and who it suits

The SYLVANIA 20875 Dulux is an 18 watt compact fluorescent lamp with a GX24Q-2 base and a warm 2700K colour temperature. It fits fixtures designed for triple tube CFLs and delivers a colour rendering index of 82. Buyers needing a different base type, a higher lumen output or an LED retrofit will not be served by this model.

Sustained output and lifetime

Rated at 12000 hours, the lamp maintains its 2700K output over long operating periods typical of commercial or residential general lighting. The 82 CRI ensures consistent colour quality throughout the rated life. Frequent short cycling can reduce the achieved hours below the published figure.

Installation notes and common issues

The GX24Q-2 four pin base plugs directly into compatible electronic ballasts; no starter is required. Verify that the ballast matches the 18 watt triple tube specification before fitting. Mismatched ballasts or reversed polarity are the usual causes of early failure or flickering.

Questions about this item

How much heat does the 18W fluorescent tube add to a room when left on all day?

At 18 watts the bulb converts most input power into light rather than heat, so the temperature rise in a typical room is minimal during continuous operation.

Does the GX24Q-2 base require a specific ballast or driver to operate?

The four-pin GX24Q-2 base is designed for electronic ballasts; the bulb will not start on a magnetic ballast or direct mains voltage.

Will this 2700K compact fluorescent match the warm tone of older incandescent bulbs I still use?

Yes, the 2700K colour temperature closely mimics traditional incandescent warmth, so mixed fixtures appear consistent.
