As a modern source of light, LEDs\u00a0open up a multitude of innovative lighting solutions. LEDs\u00a0lighting is already widely used in many niche areas like traffic\u00a0lights, car lights, lighting displays, TVs etc. Now, based\u00a0on lowered manufacturing costs, they penetrate into the\u00a0general lighting market. But for specialists, LEDs are not\u00a0yet the end solution in any lighting application. There are a\u00a0lot of factors that can influence their adoption decision.Among them, the most favorable and promising one is the\u00a0high efficiency, with values in permanent increasing. The\u00a0paper discusses various aspects of LEDs efficiency and\u00a0demonstrates that luminous efficiency is not a relevant criteria\u00a0for a decision, a better understanding being got with\u00a0an indicator like the Lighting Power Density, in W\/m2. And\u00a0beyond the efficiency, the paper makes a critical analysis of\u00a0other parameters that matters in the lighting decisionmaking<br \/>\nprocess, like lifetime, color rendering and chromatic\u00a0shift, health and environmental impact. Finally, the paper\u00a0point out that the calculation of cost and return of investment<br \/>\nrepresent a very technical effort, based on accuracy of\u00a0the entry data, often unknown by the investor itself, like\u00a0different confidential costs, daily average time of functioning,<br \/>\ntemperature hazards and lifetime in condition of poor\u00a0quality of electricity.<\/td>\n<td width=\"66\"><a href=\"http:\/\/elth.ucv.ro\/fisiere\/anale\/2015\/21.pdf\" target=\"_blank\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter  wp-image-191\" src=\"http:\/\/elth.ucv.ro\/fisiere\/anale\/wp-content\/uploads\/2015\/03\/images1.jpg\" alt=\"images\" width=\"100\" height=\"104\" \/><\/a><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"excerpt":{"rendered":"<p>Abstract\u00a0 &nbsp; Electric lighting accounts for 19% of electricity\u00a0consumption worldwide and generates remarkable concern\u00a0to get energy savings.
