The JL-103A covers residential and low-power applications with a simple, proven thermal design. The JL-412 series steps up the sensing accuracy with phototransistor technology across all three fixture types. And the JL-403C handles the high-power, wide-voltage, time-delay requirements of commercial and industrial installations. Know your fixture&#8217;s load, voltage, mounting format, and fail mode requirement, then pick the model that matches all four.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><a><\/a>\u0412\u043d\u0435\u0448\u043d\u0438\u0435 \u0441\u0441\u044b\u043b\u043a\u0438<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/en.wikipedia.org\/wiki\/Outdoor_lighting\" target=\"_blank\" rel=\"noreferrer noopener\"><u>https:\/\/en.wikipedia.org\/wiki\/Outdoor_lighting<\/u><\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/en.wikipedia.org\/wiki\/Watt\" target=\"_blank\" rel=\"noreferrer noopener\"><u>https:\/\/en.wikipedia.org\/wiki\/Watt<\/u><\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/en.wikipedia.org\/wiki\/Tungsten\" target=\"_blank\" rel=\"noreferrer noopener\"><u>https:\/\/en.wikipedia.org\/wiki\/Tungsten<\/u><\/a>\u00a0<\/li>\n\n\n\n<li><a href=\"https:\/\/en.wikipedia.org\/wiki\/Electrical_ballast\" target=\"_blank\" rel=\"noreferrer noopener\"><u>https:\/\/en.wikipedia.org\/wiki\/Electrical_ballast<\/u><\/a>\u00a0<\/li>\n\n\n\n<li><a href=\"https:\/\/en.wikipedia.org\/wiki\/IP_code\" target=\"_blank\" rel=\"noreferrer noopener\"><u>https:\/\/en.wikipedia.org\/wiki\/IP_code<\/u><\/a>\u00a0\u00a0<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>","protected":false},"excerpt":{"rendered":"<p>OUTLINE Outdoor lights play a very important role in the safety and movement of people at night.
