The bulb operates on 220-240V mains and is non-dimmable, designed for constant-brightness applications in recessed downlights, track lighting and accent fittings.\u003c\/p\u003e\n\u003cp\u003eSuited to residential living rooms, bedrooms, hallways and commercial retail or hospitality spaces where warm ambient light is preferred over cooler task lighting. The 100° beam angle provides wider coverage than traditional 38° halogen spots, reducing the number of bulbs needed to light a given area. The GU10 base fits directly into standard UK mains-voltage spotlight fittings without requiring a transformer.\u003c\/p\u003e\n\u003cp\u003eThe bulb measures 50mm diameter by 57mm height, matching the physical footprint of the halogen bulbs it replaces so there are no clearance issues in recessed housings. The spot-style reflector directs light forward rather than spilling it sideways, maintaining definition in directional lighting schemes. Rated Energy Class G under current EU labelling, the bulb draws 4.9W continuously and carries JCB's standard warranty terms.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight (KG)\u003c\/td\u003e\n\u003ctd\u003e0.03\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth (mm)\u003c\/td\u003e\n\u003ctd\u003e50\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeight (mm)\u003c\/td\u003e\n\u003ctd\u003e57\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDepth (mm)\u003c\/td\u003e\n\u003ctd\u003e50\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWattage\u003c\/td\u003e\n\u003ctd\u003e4.9W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLumen\u003c\/td\u003e\n\u003ctd\u003e345\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLamp Shape\u003c\/td\u003e\n\u003ctd\u003eSpot\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLamp Base\u003c\/td\u003e\n\u003ctd\u003eGU10\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEnergy Rating\u003c\/td\u003e\n\u003ctd\u003eG\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eKelvin\u003c\/td\u003e\n\u003ctd\u003e3,000K\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColour Temperature\u003c\/td\u003e\n\u003ctd\u003eWarm White\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\u003eBeam Angle\u003c\/td\u003e\n\u003ctd\u003e100\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLED or Halogen\u003c\/td\u003e\n\u003ctd\u003eLED\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eIs this bulb dimmable?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. This is a non-dimmable LED bulb and should not be used with dimmer switches. Installing it on a dimmer circuit may cause flickering, buzzing or premature failure. For dimmable GU10 LEDs, search the Niori catalogue for 'GU10 dimmable'.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's the beam angle and coverage?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe bulb has a 100° beam angle, significantly wider than the 38° typical of older halogen GU10s. This wider spread means fewer bulbs are needed to light a room evenly, but may produce less dramatic accent lighting in directional applications.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes it fit standard GU10 fittings?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes. The GU10 base is a standard UK mains-voltage twist-and-lock fitting. The bulb measures 50mm diameter by 57mm height, the same physical size as the 50W halogen bulbs it replaces, so it fits into existing recessed housings without clearance issues.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow does 345 lumens compare to a halogen?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e345 lumens is roughly equivalent to a 50W halogen GU10 in total light output, though the wider beam angle distributes that light differently. If your existing halogens are brighter than 50W, this LED will appear dimmer; if they were 35W, this will appear brighter.\u003c\/p\u003e","brand":"JCB","offers":[{"title":"Default Title","offer_id":46074086654219,"sku":"S10963","price":1.49,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/S10963_1_476895c3-16ce-40b2-87d0-6f6a45cfc14d.jpg?v=1730311591","url":"https:\/\/niori.co.uk\/products\/jcb-4-9w-gu10-led-bulb-3000k-warm-white-non-dimmable-345lm-50w-replacement","provider":"Niori","version":"1.0","type":"link"}
