SOX 135W Low Pressure Sodium (LPS) Light Bulb

Glow Object SOX 135W Low Pressure Sodium (LPS) Lamp — Direct Replacement for Philips SOX 135W

Direct Replacement for SOX 135W Systems

Designed as a compatible replacement for Philips SOX 135W and similar 135W low pressure sodium lamps used in existing ballast systems. Standard B22 base for large-scale outdoor infrastructure, industrial facilities, and high-output specialty applications. Ballast required, not included.

Large-Scale Road, Highway and Airport Infrastructure

The 135W output is specified for high-demand outdoor infrastructure requiring maximum coverage and light output including major highways, arterial road networks, airport perimeter and taxiway lighting, large bridge illumination, tunnel lighting systems, and interchange lighting. The high-efficacy monochromatic amber sodium output delivers strong, uniform illumination across very large outdoor areas with long lamp life and low maintenance requirements.

Port, Harbor and Coastal Industrial Lighting

Widely used in seaport facilities, harbor perimeters, marine industrial zones, offshore platform surroundings, and coastal infrastructure where high-output fog-penetrating amber sodium light is required. The 589nm sodium spectrum penetrates coastal mist, sea fog, and adverse weather conditions more effectively than white light sources, making the 135W a preferred specification for large port and marine installations.

Electronics and Industrial Inspection Lighting

The monochromatic 589nm sodium output of the SOX 135W is used in electronics manufacturing and quality control environments for LED and LCD screen inspection, display panel testing, and monochromatic light source applications where isolating specific wavelengths is required. The single-spectrum output eliminates color interference, making it suitable for industrial optical inspection, semiconductor facility lighting, and precision manufacturing environments requiring controlled monochromatic illumination.

Stage Lighting, Special Effects and Indoor Creative Use

The high-output monochromatic amber sodium glow creates an intense single-color atmosphere used in professional stage productions, large-scale theatrical lighting, cinematic film sets, immersive art exhibitions, and special effects installations requiring powerful monochromatic sodium illumination. The spectral purity and intensity of the 135W output is not replicable with LED or filtered lighting systems.

Dark Sky and Ecological Lighting

The narrow 589nm sodium spectrum produces zero blue light output, making the SOX 135W suitable for large-scale dark sky compatible infrastructure, coastal wildlife protection zones, and ecological lighting projects where minimizing light pollution across wide outdoor areas is required.

Frequently Asked Questions

How does the SOX 135W differ from the SOX 90W?

The 135W delivers higher lumen output and covers larger areas than the 90W, making it the preferred choice for major highway interchanges, airport perimeter lighting, large port facilities, and high-demand infrastructure where maximum coverage is required. Both share the same 589nm monochromatic amber spectrum and fog-penetration characteristics.

Can this lamp be used for LED and LCD screen inspection?

Yes. The monochromatic 589nm sodium output is used in electronics manufacturing and quality control for LED and LCD display panel inspection, where a single-spectrum light source eliminates color interference and allows precise optical evaluation of display components.

Does this lamp perform well in fog and extreme weather?

Yes. Low pressure sodium light at 589nm penetrates fog, rain, and coastal mist more effectively than white light sources. The SOX 135W is commonly specified for large port facilities, harbor perimeters, and coastal infrastructure for this reason.

Can this lamp be used for stage lighting and special effects?

Yes. The high-output monochromatic amber sodium glow creates a powerful single-color atmosphere used in professional stage productions, large-scale theatrical lighting, and immersive art installations. The intensity and spectral purity of the 135W output is not replicable with LED or filtered alternatives.

Does this lamp require a ballast?

Yes. A compatible 135W low pressure sodium ballast is required and is not included. This lamp is not self-ballasted.

What base does this lamp use?

Standard B22 / BY22d bayonet base, compatible with existing SOX 135W fixtures and ballast systems.

Is this lamp dark sky friendly?

Yes. The narrow 589nm sodium spectrum produces zero blue light, making it suitable for large-scale dark sky compatible infrastructure and coastal wildlife protection lighting.
