Product Identity

The SYLVANIA 20684 is a 26 watt double tube compact fluorescent bulb with a G24Q-3 4-pin base. It produces a warm 2700K colour temperature and offers a colour rendering index of 82. This light source is intended for general lighting fixtures that accept this specific base type.

Fixture Integration

The bulb requires a compatible G24Q-3 socket and an electronic ballast matched to 26 watt operation. Its 4-pin configuration ensures correct polarity and prevents use in magnetic ballast holders. The compact double tube design allows installation in recessed cans or surface mounts where longer linear tubes would not fit.

Sustained Operation

Rated life reaches 12000 hours under normal switching cycles, maintaining output over extended daily use. The 2700K warm white output remains stable throughout the rated lifespan without significant colour shift. The 82 CRI provides acceptable colour fidelity for ambient residential or commercial spaces.

Questions about this item

How long will the 12000-hour rated life last before the 26 W output drops noticeably?

The 12000-hour rating is the average point at which half the bulbs have failed; light output typically declines gradually before that, so expect a measurable drop in the later portion of the rated life.

Does the 2700 K G24Q-3 base run hot or add audible noise when left on continuously?

Compact fluorescent lamps operate cooler than incandescent equivalents and produce no audible ballast hum when the electronic ballast in the fixture is functioning correctly.

What fixture or ballast must I already have for the G24Q-3 4-pin base to work?

You need a compatible luminaire with a G24Q-3 socket and an electronic ballast rated for 26 W double-tube compact fluorescent lamps.
