The GU10 twist-and-lock base fits standard UK spotlight and downlight fittings without requiring additional adapters or modifications.\u003c\/p\u003e\n\u003cp\u003eDesigned for fixed-brightness applications in living rooms, bedrooms, hallways and kitchens, the bulb produces a soft warm white light that suits domestic interiors where ambient warmth is preferred over clinical brightness. The 345-lumen output provides sufficient illumination for general room lighting when used in clusters of 3-6 bulbs, or as accent lighting in display cabinets and alcoves when used individually.\u003c\/p\u003e\n\u003cp\u003eThe bulb carries a G energy rating under the updated EU energy labelling scale introduced in 2021, reflecting the shift in baseline standards for LED technology. JCB rates the bulb for up to 10 years of typical domestic use based on 2.7 hours per day operation. The non-dimmable design means the bulb should not be paired with dimmer switches, as this can cause flickering or premature failure.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\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\u003e345lm\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\u003eKelvin\u003c\/td\u003e\n\u003ctd\u003e3,000K\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\u003c\/table\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eCan this bulb be used with a dimmer switch?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. This is a non-dimmable LED bulb and must not be used with dimmer switches. Pairing it with a dimmer will cause flickering, buzzing or early failure. If you need dimmable GU10 LEDs, search for 'GU10 dimmable' on the Niori site.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's the equivalent halogen wattage?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThis 4.9W LED bulb replaces a 50W halogen spotlight, delivering similar brightness (345 lumens) while using approximately one-tenth of the power.

In practice, lifespan depends on usage patterns, operating temperature and mains voltage stability.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill it fit my existing spotlight fittings?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes, if your existing fittings use GU10 bulbs. The GU10 base is the standard UK twist-and-lock spotlight fitting. Simply remove the old halogen bulb by twisting anti-clockwise and insert this LED bulb by aligning the pins and twisting clockwise until it locks.\u003c\/p\u003e","brand":"JCB","offers":[{"title":"Default Title","offer_id":46253508690187,"sku":"S10965","price":1.49,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/2c16197a-7b69-48a6-9474-b20300d8ffd7_ae660964-a628-4d9e-88ac-bef1a81b1796.jpg?v=1733411707","url":"https:\/\/niori.co.uk\/products\/jcb-4-9w-gu10-led-bulb-warm-white-3000k-non-dimmable","provider":"Niori","version":"1.0","type":"link"}
