The 75mm diameter matt white ceiling rose houses the dimmer electronics, with a 1.5m white braided pull cord and a conical white pull tip for operation. The switch is wired as a 1-way circuit, meaning it controls a single light fitting from one location.\u003c\/p\u003e\n\u003cp\u003eDesigned for bathrooms, utility rooms and attic spaces where cord-operated controls are preferred or required under building regulations, the dimmer uses a pull-on\/pull-off action for switching and a pull-and-hold operation for dimming up or down. A built-in potentiometer on the dimmer module allows the dimming curve to be adjusted during installation to eliminate flicker with specific lamp types, improving compatibility across LED and incandescent light sources.\u003c\/p\u003e\n\u003cp\u003eThe 36mm-deep ceiling rose is constructed from premium-grade steel with an ABS fascia in a matt white finish. The IP20 rating limits installation to dry indoor locations only. The switch is certified to EN 60669-2 and carries Class II double-insulated wiring, so no earth connection is required. The 1.5m cord length suits ceiling heights between 2.4-2.7m, allowing the pull tip to hang at a comfortable reach height of approximately 1.8-2m from the floor.\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\u003e75 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeight\u003c\/td\u003e\n\u003ctd\u003e36 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConstruction\u003c\/td\u003e\n\u003ctd\u003ePremium grade steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConstruction 2\u003c\/td\u003e\n\u003ctd\u003e\u0026amp; ABS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFinish\u003c\/td\u003e\n\u003ctd\u003eMatt White\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\u003eIP Rating\u003c\/td\u003e\n\u003ctd\u003eIP20\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\u003eCable Length\u003c\/td\u003e\n\u003ctd\u003e1.5 m\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003e2\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_4959628_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_1363692.pdf\" target=\"_self\"\u003eProduct Manual\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's the difference between trailing-edge and leading-edge dimming?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eTrailing-edge dimmers switch off the AC waveform at the end of each cycle rather than the start, making them better suited to LED and electronic transformer loads. Leading-edge dimmers work well with incandescent and magnetic transformer loads but can cause flickering or buzzing with LEDs.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill this work with my LED bulbs?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe dimmer supports LED loads between 5-100W total. Compatibility depends on the specific LED lamp — check with the lamp manufacturer that their product is rated as dimmable and compatible with trailing-edge dimmers. The built-in potentiometer can be adjusted to fine-tune performance and reduce flicker with different lamp types.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan this be installed in a bathroom?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes, but only in zones where IP20-rated equipment is permitted under BS 7671 wiring regulations. The switch is suitable outside bathroom zones 0, 1 and 2, typically meaning installation on a ceiling at least 2.25m from a bath or shower tray. Consult a qualified electrician for confirmation on your specific installation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does 1-way mean?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e1-way means the dimmer controls a single light fitting from one location only. If you need to control the same light from two different positions (e.g. top and bottom of stairs), you would need a 2-way dimmer circuit instead.\u003c\/p\u003e","brand":"Knightsbridge","offers":[{"title":"Default Title","offer_id":45293653131531,"sku":"8301MW","price":24.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/1068312_a2ef9422-a19f-4622-ab24-12822469d39a.jpg?v=1714661905","url":"https:\/\/niori.co.uk\/products\/1-way-10-150w-trailing-edge-pull-cord-dimmer-switch-matt-white","provider":"Niori","version":"1.0","type":"link"}
