Abstract
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.
