A Comparative Analysis of Electrical and Photo Characteristics of LED Lights

An increasing shift from conventional incandescent lamps to CFLs followed by LED lights has taken place over the last few years. LED lights promise 80% energy conservation over existing lighting infrastructure and to a whopping 95% energy savings compared to the incandescent light bulbs. This paper presents a study conducted by authors on energy efficient lighting solutions in Pakistan. The study includes measurements of power and photo characteristics of a variety of LED lights obtained from international and local vendors along with an analysis and comparison with IEC standards. The work established a test bed to measure power and photo characteristics of different type of lights for comparative analysis. The results from measurements reveal a need of proactive regulatory authority to put restrictions on power characteristics and quality of available local lights. The work also demonstrates photo characteristics difference in local and international LED lights.
