SOX 90w Low Pressure Sodium Lamp Kit

The 90W SOX Lamp Kit includes everything needed to build a complete low-pressure sodium (SOX) lighting system in one convenient package. Each kit contains a matched 90W SOX lamp, electronic ballast, and BY22d lamp socket, ensuring compatibility while simplifying installation compared to sourcing components separately.

At the heart of the system is the 90W SOX lamp, which produces a pure 589nm monochromatic yellow light. Unlike conventional light sources, this narrow-spectrum output removes nearly all color information from a scene, creating the distinctive visual effect that has made SOX lighting valuable for scientific research, optical testing, large-scale installations, and immersive visual environments.

The included electronic ballast provides reliable ignition and stable operation without requiring an external ignitor, while the BY22d lamp socket ensures a secure mechanical fit and dependable electrical connection. Together, these components form a complete, purpose-built system designed for consistent performance and long-term reliability.

As the highest-output option in the SOX kit lineup, the 90W kit is ideal for larger spaces where stronger illumination is required while maintaining the unique monochromatic characteristics of SOX lighting. It is particularly well suited for exhibition spaces, museums, film and television productions, large-scale art installations, and advanced research applications.

Please note that wiring is not included. Designed for use with 90W SOX systems only.
