Description

Product Introduction

◎The sodium lamp of General High Mast Pole has significant advantages in luminous efficacy (100-150lm/W), service life (16,000-24,000 hours), fog penetration, and improved color rendering (Ra60-85), showing outstanding cost performance compared with other light sources.

◎Its electric shock protection has built an all-round safety mechanism through insulation design, TN-S grounding system (grounding resistance ≤4Ω), and residual current device below 30mA, reducing the risk of electric shock by more than 90%.

◎This product is suitable for scenarios such as transportation hubs, urban squares, and industrial sites. While ensuring lighting quality, it improves comprehensive benefits through long service life and low maintenance costs.

Excellent Performance Advantages of Sodium Lamps

(1) High luminous efficacy output for efficient energy saving

◎The luminous efficacy can reach 100-150lm/W, which is several times higher than that of traditional incandescent lamps (with luminous efficacy of about 10-20lm/W).

◎In the lighting of large squares or industrial parks, General High Mast Pole using high-pressure sodium lamps can achieve sufficient lighting over a large area with fewer lamps, greatly reducing energy consumption and saving users a lot of electricity expenses.

(2) Long service life to reduce maintenance costs

◎The average service life of low-pressure sodium lamps can reach 20,000-30,000 hours, while that of high-pressure sodium lamps is about 16,000-24,000 hours.

◎Long service life means that sodium lamps need to be replaced less frequently under the same lighting requirements. For General High Mast Pole installed at high places, reducing the number of light source replacements not only reduces the risk of high-altitude operations for maintenance personnel but also saves a lot of human and material costs.

(3) Excellent fog penetration to ensure lighting in harsh weather

◎The light emitted by sodium lamps is mainly yellow light, which has a longer wavelength and relatively weak scattering when propagating in the atmosphere, thus having extremely strong fog penetration. In harsh weather conditions such as fog and sand, the lighting effect of sodium lamps is significantly better than that of other light sources.

◎Compared with common LED street lamps, although LED lamps have good lighting effects in normal weather, their short-wavelength light is easily scattered by fog in heavy fog, resulting in reduced visibility. However, the yellow light of sodium lamps can effectively penetrate fog, providing clear lighting for roads, ports and other places, and ensuring traffic safety.

(4) Summary of comparative advantages of sodium lamps over other light sources

Comparative item	General High Mast Pole	Incandescent lamp	Metal halide lamp	LED lamp
