SOX 55w Low Pressure Sodium Lamp Kit

The 55W 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 55W SOX lamp, electronic ballast, and BY22d lamp socket, ensuring compatibility while simplifying installation compared to sourcing components individually.

At the heart of the system is the 55W 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, color perception studies, and immersive creative 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.

With its higher light output, the 55W kit is particularly well suited for larger experimental setups, exhibition spaces, photography studios, film productions, and art installations where stronger illumination is desired while maintaining the unique monochromatic characteristics of SOX lighting.

Please note that wiring is not included. Designed for use with 55W SOX systems only.

Q: What is included in the 55W SOX Lamp Kit?
A: The kit includes one 55W SOX lamp, one 55W electronic ballast, and one BY22d lamp socket. These components are matched to work together as a complete SOX lighting system.

Q: Do I need to purchase a ballast or socket separately?
A: No. The ballast and socket are included with the kit, eliminating the need to source compatible components individually. Please note that wiring is not included.

Q: Do I need a separate ignitor?
A: The included electronic ballast provides ignition functionality and does not require an external ignitor.

Q: Is this kit compatible with both 120V and 240V electrical systems?
A: Yes. The included ballast supports 110–240V mains voltage. Depending on the production batch, some ballasts may have diagrams or markings on the casing that reference 220–240V as the nominal or optimal operating voltage. However, these ballasts are designed to operate on both 110–120V and 220–240V AC power systems. Customers in the U.S. can use them without issue, and no voltage converter is required.

Q: Is this kit suitable for black-fire experiments?
A: Yes. The 55W SOX lamp produces a pure 589nm monochromatic light source, making it suitable for black-fire demonstrations, flame visualization, and optical experiments where higher light output is desired.
