Even a reliable controller can malfunction if the sensor placement and wiring are incorrect.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In decorative post top lights, stable operation depends on correct installation and periodic maintenance.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><a id=\"_oioys6chv2k5\"><\/a>Proper Installation for Hardwired <strong>\u5149\u96fb\u30bb\u30f3\u30b5\u30fc<\/strong><strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Correct installation prevents most switching problems in outdoor lighting systems. Installers should follow these practical rules:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Mount the photocontrol where it can detect natural ambient light without obstruction.<\/li>\n\n\n\n<li>Avoid placing the sensor near the lamp it controls. The direct light can cause repeated on-off cycling.<\/li>\n\n\n\n<li>Position the sensor so it represents true environmental lighting conditions.<\/li>\n\n\n\n<li>Use weatherproof wiring to prevent water ingress.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Many installers orient the photocell away from direct sunrise and sunset exposure.
