Small gaps in the specification can create major problems during installation. A strong light photocell&nbsp;bid should clearly define: This gives every supplier the same technical benchmark. It also helps municipalities avoid choosing products based only on price. But what should you include in the tender? This guide explains the key requirements for preparing a practical photocell switch specification for large-scale LED street lighting projects. What Electrical Requirements Should a Photosensor&nbsp;Bid Define? Start by defining the operating conditions in the tender. The specification should state the supply voltage, switching load, LED driver compatibility, and receptacle type. These values should match the actual luminaires [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":6380,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_seopress_titles_title":"","_seopress_titles_desc":"","_seopress_robots_index":"","_seopress_robots_follow":"","_seopress_robots_imageindex":"","_seopress_robots_snippet":"","_seopress_robots_primary_cat":"","_seopress_robots_breadcrumbs":"","_seopress_robots_freeze_modified_date":"","_seopress_robots_custom_modified_date":"","_seopress_robots_canonical":"","_seopress_social_fb_title":"","_seopress_social_fb_desc":"","_seopress_social_fb_img":"","_seopress_social_fb_img_attachment_id":0,"_seopress_social_fb_img_width":0,"_seopress_social_fb_img_height":0,"_seopress_social_twitter_title":"","_seopress_social_twitter_desc":"","_seopress_social_twitter_img":"","_seopress_social_twitter_img_attachment_id":0,"_seopress_social_twitter_img_width":0,"_seopress_social_twitter_img_height":0,"_seopress_redirections_value":"","_seopress_redirections_enabled":"","_seopress_redirections_enabled_regex":"","_seopress_redirections_logged_status":"","_seopress_redirections_param":"","_seopress_redirections_type":0,"_seopress_analysis_target_kw":"","footnotes":""},"categories":[1,185,184],"tags":[],"class_list":["post-6354","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-blog","category-knowledge","category-news"],"_links":{"self":[{"href":"https:\/\/leaditop.com\/ja\/wp-json\/wp\/v2\/posts\/6354","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/leaditop.com\/ja\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/leaditop.com\/ja\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/leaditop.com\/ja\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/leaditop.com\/ja\/wp-json\/wp\/v2\/comments?post=6354"}],"version-history":[{"count":1,"href":"https:\/\/leaditop.com\/ja\/wp-json\/wp\/v2\/posts\/6354\/revisions"}],"predecessor-version":[{"id":6382,"href":"https:\/\/leaditop.com\/ja\/wp-json\/wp\/v2\/posts\/6354\/revisions\/6382"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/leaditop.com\/ja\/wp-json\/wp\/v2\/media\/6380"}],"wp:attachment":[{"href":"https:\/\/leaditop.com\/ja\/wp-json\/wp\/v2\/media?parent=6354"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/leaditop.com\/ja\/wp-json\/wp\/v2\/categories?post=6354"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/leaditop.com\/ja\/wp-json\/wp\/v2\/tags?post=6354"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
