The CCT adjustment is set via a switch on the LED gear tray before installation, allowing the bulkhead to be configured for warm white (3000K, 1680 lumens), neutral white (4000K, 1790 lumens) or cool white (6000K, 1810 lumens) output depending on the application.\u003c\/p\u003e\n\u003cp\u003eDesigned for outdoor use on building perimeters, car parks, loading bays, communal pathways and industrial sites, the bulkhead carries an IP65 rating for full protection against dust and water ingress. The daylight sensor switches the bulkhead on at dusk and off at dawn, reducing energy consumption by preventing the light from operating during daylight hours. The emergency function provides maintained, non-maintained or switched-maintained operation during mains power failures, with a backup output of 190-200 lumens in emergency mode depending on CCT selection.\u003c\/p\u003e\n\u003cp\u003eThe die-cast aluminium body and impact-resistant polycarbonate diffuser give the bulkhead vandal-resistant durability, while the opal diffuser spreads the 110-degree beam evenly across the lit area without glare hotspots. The housing is secured with anti-tamper fixings to resist unauthorised removal. At 18W input with an efficacy of 132.6 lumens per watt, the bulkhead offers a low-running-cost alternative to traditional 70W SON bulkheads, and the SMD LED array is rated for 50,000 hours to L70B50, meaning the bulkhead will still deliver 70% of its initial output after 50,000 hours of operation.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiameter\u003c\/td\u003e\n\u003ctd\u003e360 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProjection\u003c\/td\u003e\n\u003ctd\u003e92 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConstruction\u003c\/td\u003e\n\u003ctd\u003eDie-cast aluminium\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFinish\u003c\/td\u003e\n\u003ctd\u003eGrey\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eClass\u003c\/td\u003e\n\u003ctd\u003eI\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIP Rating\u003c\/td\u003e\n\u003ctd\u003eIP65\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePrimary Voltage\u003c\/td\u003e\n\u003ctd\u003e230V 50Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiffuser\u003c\/td\u003e\n\u003ctd\u003eOpal\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEmergency\u003c\/td\u003e\n\u003ctd\u003eMaintained \/ Non-maintained \/ Switched\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLamp Technology\u003c\/td\u003e\n\u003ctd\u003eSMD LED\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimmable\u003c\/td\u003e\n\u003ctd\u003eNo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eL70B50\u003c\/td\u003e\n\u003ctd\u003e50000\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEnergy Rating (Class) post 2021 SLR\u003c\/td\u003e\n\u003ctd\u003eD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBeam Angle\u003c\/td\u003e\n\u003ctd\u003e110\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCCT\u003c\/td\u003e\n\u003ctd\u003e3000\/4000\/6000 K\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLumens\u003c\/td\u003e\n\u003ctd\u003e1680\/1790\/1810 lm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLumens (Light Source only)\u003c\/td\u003e\n\u003ctd\u003e3000 lm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLumens (Em. mode)\u003c\/td\u003e\n\u003ctd\u003e190\/200\/190 lm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWattage\u003c\/td\u003e\n\u003ctd\u003e18\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEfficacy\u003c\/td\u003e\n\u003ctd\u003e132.6 lm\/W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCRI\u003c\/td\u003e\n\u003ctd\u003e\u0026gt;85\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDriver Type\u003c\/td\u003e\n\u003ctd\u003eConstant Current\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003e5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty Information\u003c\/td\u003e\n\u003ctd\u003eExcluding battery\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch5\u003eDownloads\u003c\/h5\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/products_3327612_datasheet.pdf\" target=\"_blank\"\u003eProduct Specification Sheet\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/manual_881242.pdf\" target=\"_self\"\u003eProduct Manual\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eHow is the colour temperature adjusted?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe CCT is set via a selector switch on the LED gear tray inside the bulkhead.

In maintained mode, the bulkhead stays on continuously and switches to battery backup during power cuts. In non-maintained mode, it only illuminates during mains failure. Switched-maintained allows mains control when power is present, switching to battery backup if the mains fails.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs this suitable for coastal environments?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe die-cast aluminium body and IP65 rating make the bulkhead suitable for outdoor use in rain, dust and moisture. However, in marine or coastal environments with high salt exposure, the grey powder-coated aluminium may corrode faster than stainless steel alternatives. Regular inspection and maintenance of fixings and seals is recommended in these conditions.\u003c\/p\u003e","brand":"Knightsbridge","offers":[{"title":"Default Title","offer_id":45293955973387,"sku":"SHE1GEMP","price":88.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/199468_5b86cdaf-6a0f-4d15-9ae5-297c134e3e9a.jpg?v=1714666784","url":"https:\/\/niori.co.uk\/products\/18w-outdoor-led-bulkhead-cct-adjustable-emergency-daylight-sensor-grey-ip65","provider":"Niori","version":"1.0","type":"link"}
