Low Pressure Sodium Light Fixtures Outdoor

Essential Aspects of Low Pressure Sodium Light Fixtures Outdoor

Low pressure sodium (LPS) light fixtures are a common choice for outdoor lighting due to their energy efficiency and long lifespan. These fixtures emit a characteristic orange-yellow light that provides excellent visibility with minimal glare. Understanding the key aspects of LPS light fixtures is crucial for making informed decisions when selecting and installing these lighting solutions.

Light Output and Efficiency

LPS fixtures produce a high lumen output while consuming relatively low energy. This makes them highly energy-efficient, resulting in significant cost savings over time. The orange-yellow light emitted by LPS fixtures is particularly effective for nighttime lighting, providing clear visibility for pedestrians, cyclists, and motorists.

Long Lifespan

LPS light fixtures have an exceptionally long lifespan, typically ranging from 18,000 to 24,000 hours. This reduces the need for frequent lamp replacements and associated maintenance costs. The extended lifespan makes LPS fixtures a cost-effective choice for long-term outdoor lighting applications.

Color Rendering

The orange-yellow light emitted by LPS fixtures has a low color rendering index (CRI). This means that objects illuminated by LPS light may appear distorted in color. However, LPS light is ideal for areas where accurate color rendering is not a primary concern, such as roadways, parking lots, and industrial spaces.

Spacing and Mounting

Proper spacing and mounting are crucial for effective outdoor lighting with LPS fixtures. The spacing between fixtures depends on the desired light levels and the specific application. LPS fixtures can be mounted on poles, walls, or even suspended from ceilings. Correct mounting ensures optimal light distribution and minimizes glare.

Environmental Concerns

LPS fixtures contain sodium vapor, which is a hazardous material. Proper disposal is essential to prevent environmental contamination. It is recommended to consult local regulations for the appropriate disposal methods of used LPS lamps.

Conclusion

Low pressure sodium light fixtures are a reliable and cost-effective choice for outdoor lighting. Their energy efficiency, long lifespan, and high visibility make them ideal for roadways, parking lots, and industrial areas. Understanding the essential aspects of LPS fixtures, including light output, color rendering, spacing, mounting, and environmental concerns, is crucial for maximizing their effectiveness and minimizing potential drawbacks.
