Safety and Durability
Select lighting fixtures that are specifically designed for high-traffic and demanding environments like subways. They should have sturdy construction, be resistant to moisture, dust, and vibrations, and comply with relevant safety standards.
Energy Efficiency
Opt for energy-efficient lighting fixtures to reduce power consumption and operating costs. LED lighting technology is highly recommended due to its long lifespan, low energy consumption, and excellent illumination quality.
Illumination Level
Consider the required level of illumination for different areas within the subway, such as platforms, corridors, and ticketing areas. Proper lighting levels not only enhance visibility but also improve passenger safety and comfort.
Uniformity and Glare Control
Aim for uniform lighting distribution to eliminate dark spots or excessively bright areas. Use fixtures with appropriate optics to minimize glare, ensuring that passengers' vision is not negatively affected.
Maintenance and Reliability
Choose lighting fixtures that are easy to maintain and have a robust design to withstand frequent cleaning, electrical maintenance, and potential vandalism. Quick and hassle-free lamp replacement mechanisms can significantly reduce downtime.
Emergency Lighting
Install backup lighting systems, such as battery-powered emergency lights or luminous exit signs, to provide illumination during power outages or emergencies. These systems should comply with applicable safety regulations.
Environmental Impact
Consider environmental factors and choose fixtures that are environmentally friendly, such as those made from recyclable materials or with minimal hazardous substances.
Compatibility with Metro Infrastructure
Ensure that the selected lighting fixtures are compatible with existing metro infrastructure, including wiring systems, control panels, and emergency systems. Consult with professionals to ensure seamless integration and compatibility.
Cost-effectiveness
Evaluate the initial costs, operating costs, and maintenance requirements of different lighting options. Consider the long-term benefits and return on investment (ROI) to make an informed decision.
