Thus, a 100 W light bulb that delivers a luminous flux of 1500 lm has a luminous efficacy of 15 lm\/W. This means that only part of the electrical power absorbed by a light bulb is converted into visible light radiation. The remaining power is mainly emitted in the infrared range and is thus detectable as thermal radiation.<\/span><\/p>\n\t<div id=\"gap-101106217\" class=\"gap-element clearfix\" style=\"display:block; height:auto;\">\n\t\t\n<style>\n#gap-101106217 {\n  padding-top: 30px;\n}\n<\/style>\n\t<\/div>\n\t\n\n<div class=\"row\"  id=\"row-1836067464\">\n\n\n\t<div id=\"col-2044471636\" class=\"col small-12 large-12\"  >\n\t\t\t\t<div class=\"col-inner\"  >\n\t\t\t\n\t\t\t\n\n\t<div id=\"gap-1139872031\" class=\"gap-element clearfix\" style=\"display:block; height:auto;\">\n\t\t\n<style>\n#gap-1139872031 {\n  padding-top: 30px;\n}\n<\/style>\n\t<\/div>\n\t\n\n<div class=\"container section-title-container\" ><h3 class=\"section-title section-title-normal\"><b><\/b><span class=\"section-title-main\" >Related Topics<\/span><b><\/b><\/h3><\/div>\n\n\n  \n    <div class=\"row large-columns-3 medium-columns-1 small-columns-1 has-shadow row-box-shadow-2 row-box-shadow-5-hover slider row-slider slider-nav-reveal slider-nav-push\"  data-flickity-options='{&quot;imagesLoaded&quot;: true, &quot;groupCells&quot;: &quot;100%&quot;, &quot;dragThreshold&quot; : 5, &quot;cellAlign&quot;: &quot;left&quot;,&quot;wrapAround&quot;: true,&quot;prevNextButtons&quot;: true,&quot;percentPosition&quot;: true,&quot;pageDots&quot;: false, &quot;rightToLeft&quot;: false, &quot;autoPlay&quot; : false}' >\n\n  <div class=\"col post-item\" >\n\t\t\t<div class=\"col-inner\">\n\t\t\t\t<div class=\"box box-normal box-text-bottom box-blog-post has-hover\">\n          \t\t\t\t\t<div class=\"box-text text-left\" >\n\t\t\t\t\t<div class=\"box-text-inner blog-post-inner\">\n\n\t\t\t\t\t\n\t\t\t\t\t\t\t\t\t\t<h5 class=\"post-title is-large \">\n\t\t\t\t\t\t<a href=\"https:\/\/book2net.net\/en\/2022\/08\/23\/lumen\/\" class=\"plain\">Lumen<\/a>\n\t\t\t\t\t<\/h5>\n\t\t\t\t\t\t\t\t\t\t<div class=\"is-divider\"><\/div>\n\t\t\t\t\t\t\t\t\t\t<p class=\"from_the_blog_excerpt \">\n\t\t\t\t\t\tLumen (lm) is the internationally standardized unit of [...]\t\t\t\t\t<\/p>\n\t\t\t\t\t                    \n\t\t\t\t\t\t\t\t\t\t\t<a href=\"https:\/\/book2net.net\/en\/2022\/08\/23\/lumen\/\" class=\"button  is-underline is-large mb-0\">\n\t\t\t\t\t\t\tREAD MORE\t\t\t\t\t\t<\/a>\n\t\t\t\t\t\n\t\t\t\t\t\n\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t<\/div>\n\t\t<\/div><\/div>\n\n\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\n\t\n\n<\/div>\n\n","protected":false},"excerpt":{"rendered":"<p>The luminous efficacy of a light source is its efficiency or energy efficiency, which is the quotient of luminous flux (lumen) and absorbed electrical power (watt).<\/p>\n","protected":false},"author":3,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[279,308],"tags":[],"class_list":["post-18055","post","type-post","status-publish","format-standard","hentry","category-glossary","category-l-glossary"],"_links":{"self":[{"href":"https:\/\/book2net.net\/en\/wp-json\/wp\/v2\/posts\/18055","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/book2net.net\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/book2net.net\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/book2net.net\/en\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/book2net.net\/en\/wp-json\/wp\/v2\/comments?post=18055"}],"version-history":[{"count":5,"href":"https:\/\/book2net.net\/en\/wp-json\/wp\/v2\/posts\/18055\/revisions"}],"predecessor-version":[{"id":18060,"href":"https:\/\/book2net.net\/en\/wp-json\/wp\/v2\/posts\/18055\/revisions\/18060"}],"wp:attachment":[{"href":"https:\/\/book2net.net\/en\/wp-json\/wp\/v2\/media?parent=18055"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/book2net.net\/en\/wp-json\/wp\/v2\/categories?post=18055"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/book2net.net\/en\/wp-json\/wp\/v2\/tags?post=18055"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
