The Light Head Hanger system is an accessory for the NIGHTSEA Stereo Microscope Fluorescence Adapter. It is a combination of power extension cables and custom made holders that enables you to take the fluorescence excitation light heads off the gooseneck and mount them directly on the SFA adapter ring. In addition, it provides the capability to drive two light heads from one lamp base.<\/p>\n","protected":false},"featured_media":0,"template":"","meta":{"_acf_changed":false,"_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":"","_seopress_news_disabled":"","_seopress_video_disabled":"","_seopress_video":[],"_seopress_pro_schemas_manual":[],"_seopress_pro_rich_snippets_disable_all":"","_seopress_pro_rich_snippets_disable":[],"_seopress_pro_schemas":[]},"product_brand":[1894],"product_cat":[1379,1891,1892,1903],"product_tag":[],"class_list":["post-30404","product","type-product","status-publish","product_brand-nightsea","product_cat-microscopie-optique","product_cat-nightsea","product_cat-nightsea-fluorescence","product_cat-nightsea-accessories","first","instock","taxable","shipping-taxable","purchasable","product-type-simple"],"acf":[],"_links":{"self":[{"href":"https:\/\/delta.screenup.com\/en\/wp-json\/wp\/v2\/product\/30404","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/delta.screenup.com\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/delta.screenup.com\/en\/wp-json\/wp\/v2\/types\/product"}],"wp:attachment":[{"href":"https:\/\/delta.screenup.com\/en\/wp-json\/wp\/v2\/media?parent=30404"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/delta.screenup.com\/en\/wp-json\/wp\/v2\/product_brand?post=30404"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/delta.screenup.com\/en\/wp-json\/wp\/v2\/product_cat?post=30404"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/delta.screenup.com\/en\/wp-json\/wp\/v2\/product_tag?post=30404"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
