Philips SOX-E 91W

The Philips SOX-E 91W sodium discharge lamp is a tubular light source designed for industrial, commercial, and technical lighting applications that require high energy efficiency and concentrated light output.

Industrial Lighting and High-Efficiency Discharge Systems

This sodium lamp is the ideal solution for production facilities, warehouses, industrial buildings, and work areas where luminous efficiency is a priority. With a luminous flux of 17,400 lumens and an efficiency of 191.2 lm/W, it provides powerful lighting while reducing energy consumption. Its tubular shape and Y22D base make it compatible with traditional discharge lighting fixtures.

Applications in Street and Public Lighting

The sodium-T lamp power supply is frequently used in street lighting systems, parking lots, and public areas where very warm white light (1,800K) creates a welcoming atmosphere while maintaining extremely low energy consumption. The average lifespan of 18,000 hours minimizes maintenance and replacement needs.

Commercial and retail sectors with energy constraints

Stores, showrooms, and commercial spaces requiring diffuse and uniform lighting find the sodium-T lamp to be a cost-effective solution. Energy Class A certifies compliance with European efficiency standards, making it ideal for systems that must meet stringent environmental regulations.

Design Features and Compatibility

The 66 mm diameter and 775 mm length ensure compatibility with standard fixtures. The lamp is not dimmable, guaranteeing stable and predictable performance. A color rendering index (CRI) below 30 is typical of sodium-T light sources, which are suitable for applications where color accuracy is not critical but pure luminous efficiency is paramount.

Advantages of Sodium-T Technology for Energy Savings

Choosing a sodium transformer and lamp means investing in reliability and reduced operating costs. Sodium discharge technology is well-established, with readily available replacement parts and simplified maintenance. Ideal for those seeking the best balance between light output and power consumption in industrial and public settings.
