{"product_id":"crestron-gls-lcct","title":"Crestron GLS-LCCT – SolarSync Outdoor Daylight and Color Temperature Sensor","description":"\u003ch2\u003eProduct Overview\u003c\/h2\u003e\u003cp\u003eThe Crestron GLS-LCCT SolarSync is an outdoor daylight and correlated color temperature (CCT) sensor designed for integration with Crestron lighting control systems. It measures both light intensity (0-100,000 lux) and color temperature (2,000K-25,000K) using multi-spectral sensing technology, enabling Crestron systems to automatically adjust tunable white lighting fixtures to match natural daylight conditions throughout the day. It is intended for rooftop, exterior wall, or skylight-adjacent installations.\u003c\/p\u003e\u003ch2\u003eProduct Description\u003c\/h2\u003e\u003cp\u003eThe GLS-LCCT communicates via Cresnet slave mode and connects to the Crestron system with a 3 ft attached cable with four flying leads. Its 360° semispherical field of view captures ambient light from the full overhead hemisphere, providing accurate measurements regardless of sun position. The IP67 rating ensures protection from dust ingress and submersion, making it suitable for exposed outdoor mounting in all weather conditions. A PTFE housing with acrylic diffused dome provides UV and chemical resistance. Mounting is via a 1\/2 in. conduit knockout to a standard j-box or enclosure.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eDual measurement: light intensity (0-100,000 lux) and correlated color temperature (2,000K-25,000K)\u003c\/li\u003e\n\u003cli\u003eMulti-Spectral Sensing Engine with CIE 1931 2° Standard Observer coordinates\u003c\/li\u003e\n\u003cli\u003e360° semispherical field of view for full ambient light capture\u003c\/li\u003e\n\u003cli\u003eIP67 rated: dust tight and waterproof per IEC\/EN 60529\u003c\/li\u003e\n\u003cli\u003eCresnet slave mode; 5W power via Cresnet (209 mA @ 24 VDC)\u003c\/li\u003e\n\u003cli\u003ePTFE housing with acrylic diffused dome; UV and chemical resistant\u003c\/li\u003e\n\u003cli\u003e3 ft (0.91 m) attached cable with 4 flying leads (24 AWG)\u003c\/li\u003e\n\u003cli\u003eCertifications: CE\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTypical Applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eOutdoor daylight sensor for Crestron circadian lighting control systems\u003c\/li\u003e\n\u003cli\u003eTunable white lighting automation in offices, schools, and healthcare facilities\u003c\/li\u003e\n\u003cli\u003eRooftop daylight harvesting sensor for commercial building energy management\u003c\/li\u003e\n\u003cli\u003eResidential whole-home lighting color temperature automation throughout the day\u003c\/li\u003e\n\u003cli\u003eSkylighted spaces where indoor color temperature should track outdoor daylight\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e GLS-LCCT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.31 lb (142 g)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 2.77 in.

This allows Crestron to adjust both the brightness and the color temperature of tunable white fixtures simultaneously to match outdoor daylight conditions.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQ: Does the GLS-LCCT require an outdoor-rated enclosure?\u003c\/strong\u003e\u003cbr\u003eA: The GLS-LCCT is IP67 rated and is itself weatherproof. It mounts via a standard 1\/2 in. conduit knockout to a j-box or enclosure. The j-box used for mounting should be appropriately rated for outdoor installation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQ: What Crestron programming is needed to use the GLS-LCCT with tunable white fixtures?\u003c\/strong\u003e\u003cbr\u003eA: The GLS-LCCT sends lux and CCT data via Cresnet to a Crestron processor. Programming to translate those readings into control signals for specific tunable white fixtures depends on the system configuration. Crestron provides programming modules and documentation for common lighting control scenarios.\u003c\/p\u003e","brand":"Crestron","offers":[{"title":"Default Title","offer_id":47759586066668,"sku":"GLS-LCCT","price":1090.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0603\/7982\/4364\/files\/master_photo_a-gls-lcct_side.png?v=1781800026","url":"https:\/\/creationnetworks.net\/products\/crestron-gls-lcct","provider":"Creation Networks","version":"1.0","type":"link"}
