Abstract:Lighting is a thoughtful application of lighting source to get visibility and accomplish a specific task during the darkness by providing desirable illumination. In present context, there are numerous light sources and lighting technologies. But, with the advancement of technologies, traditional lighting technique is being gradually replaced by efficient lighting system with specific purpose and application. This study presents current status of lighting technologies, applications, challenges, policies and impacts in Nepalese scenario. This study also presents some statistic outcome, drawn from a survey of 250 sample size including different five target group. From this study, it is found that the people and government are moving toward the efficient and clean lighting technologies from traditional one. These activities on the implementation of efficient lighting technologies help the people in different sectors, such as education, health, security, economy etc., and in the improvement of living standard.
