The sensor detects movement through walls and obstacles, switching the light on automatically when motion is detected within the configured range. The bulkhead supports three wattage settings (9W, 14W, 18W) and three colour temperatures (3000K, 4000K, 5700K), both adjustable via DIP switches behind the diffuser.\u003c\/p\u003e\n\u003cp\u003eDesigned for stairwells, bin stores, external walls, car parks and controlled-access zones, the BT Evo reduces energy use in low-traffic areas by switching off automatically after a configurable hold period. The microwave sensor includes a slave live terminal that can trigger linked fittings without additional sensors, allowing one BT Evo to control a zone of non-sensor bulkheads. The opal polycarbonate diffuser provides 120-degree beam spread, and the white housing accepts clip-on bezels in alternative finishes for aesthetic matching.\u003c\/p\u003e\n\u003cp\u003eThe 300mm diameter white polycarbonate body projects 65mm from the wall or ceiling. The IP65 rating protects against dust ingress and water jets from any direction, while the IK10 rating withstands impacts up to 20 joules — suitable for public areas, sports facilities and sites at risk of accidental or deliberate damage. The UV-stabilised polycarbonate resists yellowing and embrittlement in outdoor installations. Tool-free cable access and loop-in\/loop-out terminals simplify installation and reduce fitting time.\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\u003e300mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProjection\u003c\/td\u003e\n\u003ctd\u003e65mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConstruction\u003c\/td\u003e\n\u003ctd\u003ePolycarbonate\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFinish\u003c\/td\u003e\n\u003ctd\u003eWhite\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBezel Included\u003c\/td\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInterchangeable Bezel\u003c\/td\u003e\n\u003ctd\u003eClip On\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\u003eClass\u003c\/td\u003e\n\u003ctd\u003eII\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\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\u003e120\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCCT\u003c\/td\u003e\n\u003ctd\u003e3000\/4000\/5700K\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLight Colour\u003c\/td\u003e\n\u003ctd\u003eCCT\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLumens\u003c\/td\u003e\n\u003ctd\u003e890\/930\/915,1295\/1400\/1330,1520\/1750\/1585lm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLumens (Light source only)\u003c\/td\u003e\n\u003ctd\u003e1215\/1900\/2300lm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWattage\u003c\/td\u003e\n\u003ctd\u003e9\/14\/18W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEfficacy (Light source)\u003c\/td\u003e\n\u003ctd\u003e136\/136\/134lm\/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 Year Guarantee\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\/datasheet-BTEVMW.pdf\" target=\"_blank\"\u003eProduct Specification Sheet\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eHow does the microwave sensor work?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe microwave sensor detects movement through walls, doors and glass, unlike PIR sensors which require direct line of sight. Detection range, sensitivity and hold time are adjustable via controls behind the diffuser. The sensor triggers the light when motion is detected and switches off automatically after the configured hold period.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan the wattage and colour temperature be changed after installation?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes. Both wattage (9W, 14W or 18W) and colour temperature (3000K, 4000K or 5700K) are adjusted via DIP switches accessible behind the diffuser. This allows one SKU to serve multiple site requirements without stocking separate variants.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the IK10 rating?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eIK10 is the highest rating on the international impact resistance scale. It means the bulkhead can withstand impacts of up to 20 joules — equivalent to a 5kg mass dropped from 400mm. This makes it suitable for public areas, sports facilities and sites at risk of vandalism.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the slave live terminal used for?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe slave live terminal allows the BT Evo to trigger other bulkheads or fittings without their own sensors. When the microwave sensor detects motion, it switches both the BT Evo and any connected slave fittings, reducing the number of sensors needed in a zone.\u003c\/p\u003e","brand":"Knightsbridge","offers":[{"title":"Default Title","offer_id":51391658688779,"sku":"BTEVMW","price":25.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/1851494_0ddaaf88-590b-4eb0-aa5d-fad61b7aaaf9.jpg?v=1747063247","url":"https:\/\/niori.co.uk\/products\/knightsbridge-bt-evo-18w-led-bulkhead-microwave-sensor-ik10-ip65-white","provider":"Niori","version":"1.0","type":"link"}
