This article we will let you how the photometric testing is made with photometer, definition of symmetric and asymmetric lighting distribution, how to distinguish these lighting distribution. And we will also let you know the application of asymmetric lighting distribution in street lighting and flood lighting. All these we think are very useful for your project.","name":"Photometric testing - symmetric or asymmetric lighting distribution | ZGSM","@id":"#richSnippet","isPartOf":{"@id":"#webpage"},"image":{"@id":"https:/wp-content/uploads/2023/02/1677218452-Photometric-testing.jpg"},"inLanguage":"en-US","mainEntityOfPage":{"@id":"#webpage"}}]} document.documentElement.classList.remove( 'no-js' ); window._wpemojiSettings = {"baseUrl":"https:\/\/s.w.org\/images\/core\/emoji\/15.0.3\/72x72\/","ext":".png","svgUrl":"https:\/\/s.w.org\/images\/core\/emoji\/15.0.3\/svg\/","svgExt":".svg","source":{"concatemoji":"https:\/\/www.zgsm-china.com\/wp-includes\/js\/wp-emoji-release.min.js?ver=6.7"}}; /*!
