As part of the WattStopper Digital Lighting Management (DLM) system, the LMLS-400 provides closed-loop daylight harvesting control by continuously monitoring light levels and communicating with compatible room controllers. The sensor features photopic correction to mimic the human eye and an extended sensing range, making it ideal for energy-efficient lighting control in commercial and institutional facilities. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-section-id=\"5ms9th\" data-start=\"685\" data-end=\"702\"\u003eApplications:\u003c\/h3\u003e\n\u003cp data-start=\"703\" data-end=\"1228\"\u003eThe WattStopper LMLS-400 Closed Loop Photosensor is commonly used in office buildings, educational facilities, healthcare institutions, conference rooms, retail spaces, commercial buildings, government facilities, and energy management systems where automatic daylight harvesting, lighting control, energy savings, occupancy-based lighting strategies, and single-zone dimming or switching control are required to maintain consistent illumination levels while reducing energy consumption. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-section-id=\"5hg6bl\" data-start=\"1230\" data-end=\"1259\"\u003eTechnical Specifications:\u003c\/h3\u003e\n\u003cp data-start=\"1260\" data-end=\"2083\"\u003e• Manufacturer: WattStopper \/ Legrand\u003cbr data-start=\"1297\" data-end=\"1300\"\u003e• Model: LMLS-400\u003cbr data-start=\"1317\" data-end=\"1320\"\u003e• Product Type: Closed Loop Digital Photosensor\u003cbr data-start=\"1367\" data-end=\"1370\"\u003e• Control Zones: 1 Zone\u003cbr data-start=\"1393\" data-end=\"1396\"\u003e• Function: Automatic daylight-responsive switching and dimming\u003cbr data-start=\"1459\" data-end=\"1462\"\u003e• System Compatibility: Digital Lighting Management (DLM) Systems\u003cbr data-start=\"1527\" data-end=\"1530\" data-is-only-node=\"\"\u003e• Input Voltage: 24 VDC\u003cbr data-start=\"1553\" data-end=\"1556\"\u003e• Sensor Type: Photodiode with Photopic Correction\u003cbr data-start=\"1606\" data-end=\"1609\"\u003e• Sensing Range: 1–1,553 Footcandles (fc)\u003cbr data-start=\"1650\" data-end=\"1653\"\u003e• Spatial Response: 100°\u003cbr data-start=\"1677\" data-end=\"1680\"\u003e• Control Modes: On\/Off, Bi-Level, Tri-Level, and Dimming\u003cbr data-start=\"1737\" data-end=\"1740\"\u003e• Communication: DLM Local Network\u003cbr data-start=\"1774\" data-end=\"1777\"\u003e• Connection Type: RJ-45\u003cbr data-start=\"1801\" data-end=\"1804\"\u003e• Mounting Type: Ceiling Mounted\u003cbr data-start=\"1836\" data-end=\"1839\"\u003e• Material: ABS Plastic\u003cbr data-start=\"1862\" data-end=\"1865\"\u003e• Color: White\u003cbr data-start=\"1879\" data-end=\"1882\"\u003e• Operating Temperature: 32°F to 131°F (0°C to 55°C)\u003cbr data-start=\"1934\" data-end=\"1937\"\u003e• Application Type: Daylight Harvesting and Lighting Control\u003cbr data-start=\"1997\" data-end=\"2000\"\u003e• Equipment Category: Lighting Control Sensor \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-section-id=\"1cz0398\" data-start=\"2085\" data-end=\"2109\"\u003eCommon Replacements:\u003c\/h3\u003e\n\u003cp data-start=\"2110\" data-end=\"2277\"\u003e• WattStopper LMLS-500 Open Loop Photosensor\u003cbr data-start=\"2154\" data-end=\"2157\"\u003e• Acuity Brands nLight NPS Series Photosensor\u003cbr data-start=\"2202\" data-end=\"2205\"\u003e• Leviton GreenMAX Daylight Sensor\u003c\/p\u003e","brand":"WATTSTOPPER","offers":[{"title":"New","offer_id":51731265061166,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_51ff1b48-5032-4102-8a91-6bdb3015209e.jpg?v=1770595856","url":"https:\/\/plgautomation.com\/products\/wattstopper-lmls-400-closed-loop-photosensor-1-zone","provider":"PLG Automation ","version":"1.0","type":"link"}
