Philips 18 W Triple Tube GX24Q-2 4100K Fluorescent Bulb

Philips 18 W Triple Tube GX24Q-2

This Philips fluorescent bulb draws 18 W and delivers 1200 lumens at a neutral 4100 K colour temperature. The four-pin GX24Q-2 base fits compatible recessed or surface-mounted fixtures in offices, retail spaces or residential kitchens. It suits users who need reliable general lighting from a compact triple-tube design.

Limits of the GX24Q-2 interface

The four-pin GX24Q-2 base requires a matching ballast and socket; it will not work in two-pin or other four-pin variants such as G24Q-1 or GX24Q-3. Light output is fixed at 1200 lumens and colour rendering stays at CRI 80, so the bulb cannot be dimmed or tuned without a compatible control gear. Buyers needing adjustable output or higher colour fidelity should look elsewhere.

Build and daily implications

The triple-tube glass envelope is rated for 20000 hours of operation, reducing relamping frequency in commercial installations. A CRI of 80 renders colours adequately for typical task areas but not for colour-critical work. The 4100 K output sits between warm and cool white, suiting spaces where a balanced, neutral tone is preferred.
