The formula for calculating sphericity based on beam angle is as follows: Sphericity = 2 \u00d7 \u03c0 \u00d7 (1 &#8211; cos(0.5 \u00d7 beam angle))<\/p>\n\t\t\n<style>\n#text-2556207649 {\n

on the total amount of light emitted by a light source, quantifying luminous flux to indicate how much light a source can produce; lux, however, concerns the luminous flux received per unit area by an illuminated object, reflecting the degree to which an object is lit and revealing how brightly a surface is illuminated. The nit, as a unit of luminance, applies to area sources by combining luminous intensity with the emitting area. It is commonly used to describe the visual brightness of luminous surfaces such as displays. The candela, meanwhile, is the core metric for the luminous intensity of point sources. It characterises a light source&#8217;s ability to concentrate light in a specific direction, revealing how intensely the source itself emits light.<\/p>\n\t\t\n<style>\n#text-666799553 {\n  font-size: 0.75rem;\n  line-height: 1.5;\n}\n@media (min-width:550px) {\n  #text-666799553 {\n    font-size: 1.1rem;\n    line-height: 2;\n  }\n}\n<\/style>\n\t<\/div>\n\t\n\t<div id=\"gap-1912549906\" class=\"gap-element clearfix\" style=\"display:block; height:auto;\">\n\t\t\n<style>\n#gap-1912549906 {\n  padding-top: 100px;\n}\n<\/style>\n\t<\/div>\n\t\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\n\t\n<\/div>","protected":false},"excerpt":{"rendered":"","protected":false},"author":1,"featured_media":3245,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"om_disable_all_campaigns":false,"_monsterinsights_skip_tracking":false,"footnotes":""},"categories":[84],"tags":[],"class_list":["post-3237","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-technical"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 5.0.1.1 - aioseo.com -->\n\t<meta name=\"description\" content=\"Confused by lumens, lux, nits, and candela?
