The lighting sector represents a significant component of global energy consumption, accounting for approximately 15% of worldwide electricity usage and about 5% of greenhouse gas emissions. Over the past decade, this sector has undergone a revolutionary transformation with the widespread adoption of LED (Light Emitting Diode) technology, which consumes up to 80% less energy than traditional incandescent bulbs while offering superior longevity. Smart lighting systems have further enhanced energy efficiency by incorporating sensors, timers, and network connectivity to optimize illumination based on occupancy, daylight availability, and time-of-day requirements. The integration of lighting with Internet of Things (IoT) platforms has created new opportunities for energy management, allowing for remote monitoring and control that can significantly reduce wastage. As countries worldwide implement stricter energy efficiency standards and phase out inefficient lighting technologies, the sector continues to drive innovation in areas such as human-centric lighting, which adjusts color temperature throughout the day to support human circadian rhythms while maintaining energy efficiency goals. This evolution makes lighting a critical frontier in sustainable energy strategies for both developed and developing economies.
