High-pressure sodium vapor (HPS) lamps have been widely used in industrial lighting, especially in large manufacturing facilities, and are commonly used as plant grow lights.
A high pressure sodium vapor lamp is a gas-discharge lamp that uses excited sodium to produce light. It is highly efficient and has a long lifespan

A high-pressure sodium (HPS) vapor lamp is a type of gas-discharge lamp that produces light by passing an electric current through sodium vapor under high pressure. These lamps are widely used for outdoor lighting, street lighting, and industrial applications because of their high efficiency and long lifespan.Key features of high-pressure sodium vapor lamps:
Light output: Produces a characteristic yellow-orange light, which is good for visibility in foggy or foggy conditions.
Efficiency: Known for high luminous efficacy, meaning they produce a lot of visible light per unit of power consumed.
Lifespan: Typically lasts between 12,000 to 24,000 hours.
Operation: Requires a ballast to regulate the current and voltage during startup and operation.
Color rendering: Moderate, with a low color rendering index (CRI), which means colors may not appear as naturally under HPS lighting.
Applications:
Street lighting
Industrial lighting
Floodlighting
Parking lots
Sports Stadiums
Ware House
Storage Areas
Advantages:
High efficiency
Long operational life
Good penetration in foggy conditions
Disadvantages:
Limited color rendering
Warm-up time before reaching full brightness
Contains hazardous materials like sodium, requiring proper disposal
