Product Identity

The Sylvania 20724 is an 18 watt double compact fluorescent lamp with a G24Q-2 4-pin base. It produces a warm white 3000K colour temperature and a colour rendering index of 82. Rated life is 12000 hours. It suits general indoor lighting where a compact fluorescent source is required.

Compatibility Check

Verify that the fixture accepts a G24Q-2 4-pin base before ordering. This lamp is not compatible with 2-pin G24d sockets or other pin configurations. Confirm the ballast supports 18 watt double compact fluorescent operation. Ensure the physical dimensions fit the luminaire housing.

Sustained Operation

The lamp maintains its rated 3000K output and 82 CRI across the 12000 hour design life under normal cycling. Lumen depreciation follows typical compact fluorescent curves rather than a short burst peak. Warm-up time is inherent to the technology and stabilises within minutes of continuous use.
