Replaces PHILIPS MASTER PL-L 55W/950/4p

Replacement of the PHILIPS MASTER PL-L 55W/950/4p with the OSRAM DULUX L 55W/865 (2G11)

The OSRAM DULUX L 55W/865 is a professional compact fluorescent lamp designed to deliver powerful, uniform and reliable lighting, perfectly suited to demanding environments. Its 865 Daylight light (very cool white) provides a clean and crisp visual appearance while ensuring excellent visibility, especially appreciated where precision and visual comfort are essential.

It is ideally suited for medical and dental practices, as well as offices, lobbies, retail spaces and public buildings. Its PL-L double tube design and 2G11 base (4 pins) ensure wide compatibility with many luminaires equipped with suitable control gear.

Why it effectively replaces the PHILIPS MASTER PL-L 55W/950/4p
This lamp represents a technically coherent alternative to the PHILIPS MASTER PL-L 55W/950/4p, as it retains all key parameters required for direct replacement. It operates using the same PL-L technology, the same 55 W rated power, and the same 2G11 4-pin base, allowing quick and straightforward installation in most existing luminaires, subject to ballast compatibility.

The main difference lies in the colour temperature.
The 950 version offers a more natural light with very high colour rendering, while the 865 delivers a whiter, more clinical light (6500 K). This light colour is often preferred in healthcare environments and professional spaces where maximum visibility and a neutral visual atmosphere are required.
