SOX 55W Low Pressure Sodium (LPS) Light Bulb

Glow Object SOX 55W Low Pressure Sodium (LPS) Lamp — Direct Replacement for Philips SOX 55W

Direct Replacement for SOX 55W Systems

Designed as a compatible replacement for Philips SOX 55W and similar 55W low pressure sodium lamps used in existing ballast systems. Standard B22 base for municipal street lighting, industrial installations, and infrastructure applications. Ballast required, not included.

Street Lighting and Municipal Infrastructure

The 55W output is a standard wattage for municipal and commercial street lighting installations. Commonly specified for public roads, highways, bridge underpasses, tunnel lighting, airport perimeter lighting, seaport facilities, coastal infrastructure, and HOA community street lighting. The monochromatic amber sodium spectrum provides high-efficacy uniform illumination across wide outdoor areas with minimal glare and light spill.

Dark Sky and Ecological Lighting

The narrow 589nm sodium spectrum produces zero blue light output, making the SOX 55W one of the most dark sky compatible lamp types available. Widely used in dark sky preserves, observatory surroundings, coastal nature reserves, rural communities, and ecological lighting zones where minimizing impact on nocturnal wildlife and astronomical visibility is required.

Parking, Industrial and Commercial Outdoor Use

Suitable for parking lots, industrial facility perimeters, warehouses, loading docks, commercial outdoor areas, and large-scale infrastructure lighting where consistent amber illumination and long lamp life are priorities. The 55W rating covers medium to large outdoor spaces efficiently.

Darkroom and Specialty Photography Use

Suitable for larger film developing darkroom environments, safelight applications, photography studios, and lab setups requiring stable monochromatic amber illumination across larger working spaces.

Indoor, Outdoor and Creative Atmosphere Use

Suitable for both indoor and outdoor applications with compatible fixtures and ballast systems. Used in basements, workshops, larger studios, and industrial creative spaces. Frequently used for cinematic stage lighting, retro industrial aesthetics, movie props, photography sets, Halloween installations, sci-fi themed environments, and immersive art installations requiring a distinct monochromatic amber atmosphere.
