It uses the same twist-and-lock GU10 base as the halogen spotlight it replaces, so it drops straight into an existing GU10 downlight or spotlight fitting with no rewiring and no transformer required.\u003c\/p\u003e\n\u003ch2\u003eKey features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e350 lumen output, 3000K warm white colour temperature\u003c\/li\u003e\n\u003cli\u003e4.9W actual power draw, marketed as a 50W halogen replacement\u003c\/li\u003e\n\u003cli\u003eStandard twist-and-lock GU10 base, fits directly into existing GU10 fittings\u003c\/li\u003e\n\u003cli\u003eNon-dimmable — do not fit to a dimmer circuit\u003c\/li\u003e\n\u003cli\u003e220-240V, runs directly from UK mains with no transformer needed\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWhat this bulb is best for\u003c\/h2\u003e\n\u003cp\u003eA budget-friendly, everyday warm white GU10 for kitchens, hallways, living rooms and any fitting on a standard (non-dimmer) switch where a cosy, traditional light colour is wanted.\u003c\/p\u003e\n\u003ch2\u003eHow to fit it\u003c\/h2\u003e\n\u003cp\u003eSwitch off the power at the wall or light switch before changing any bulb. If the old bulb has just been in use, let it cool for a minute or two before touching it. Twist the old GU10 bulb anticlockwise until the two pins release from the ceramic base, then pull it straight out. Line up the pins of the new JCB bulb with the two slots in the fitting, push in gently and twist clockwise until it locks into place. Restore power and test the light. No transformer or driver is needed — GU10 LED bulbs run directly from the UK mains supply.\u003c\/p\u003e\n\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\n\u003ch3\u003eCan this JCB GU10 bulb be used with a dimmer switch?\u003c\/h3\u003e\n\u003cp\u003eNo. This bulb is non-dimmable and should only be fitted to a standard on\/off GU10 circuit. Fitting a non-dimmable LED to a dimmer switch can cause flickering, buzzing or early failure.\u003c\/p\u003e\n\u003ch3\u003eWhat halogen bulb does this replace?\u003c\/h3\u003e\n\u003cp\u003eIt's sold as a 50W halogen GU10 replacement, giving comparable brightness from a fraction of the power draw.\u003c\/p\u003e\n\u003ch3\u003eWhy is the energy rating shown as G rather than A?\u003c\/h3\u003e\n\u003cp\u003eThe UK\/EU energy label was rescaled in 2021 to make room for future efficiency gains, so ratings for many everyday LED GU10 bulbs now sit lower on the new A-G scale than they did under the old system. A G rating here reflects this budget bulb's position on the newer, stricter scale — it is still far more efficient than a halogen GU10.\u003c\/p\u003e\n\u003ch3\u003eDoes this bulb need a transformer?\u003c\/h3\u003e\n\u003cp\u003eNo. GU10 LED bulbs, including this one, run directly from 220-240V mains with no transformer or separate driver required.\u003c\/p\u003e\n\u003ch2\u003eTechnical specification\u003c\/h2\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eBrand\u003c\/th\u003e\n\u003ctd\u003eJCB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBulb type\u003c\/th\u003e\n\u003ctd\u003eLED GU10\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWattage\u003c\/th\u003e\n\u003ctd\u003e4.9W (marketed as 5W, 50W halogen replacement)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eLumens\u003c\/th\u003e\n\u003ctd\u003e350 lumen (345 lumen measured)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eColour temperature\u003c\/th\u003e\n\u003ctd\u003e3000K warm white\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBeam angle\u003c\/th\u003e\n\u003ctd\u003eNot stated by manufacturer\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDimmable\u003c\/th\u003e\n\u003ctd\u003eNo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBase type\u003c\/th\u003e\n\u003ctd\u003eGU10\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eVoltage\u003c\/th\u003e\n\u003ctd\u003e220-240V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eRated life\u003c\/th\u003e\n\u003ctd\u003eNot stated by manufacturer\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePack size\u003c\/th\u003e\n\u003ctd\u003eSingle\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eProduct code\u003c\/th\u003e\n\u003ctd\u003e362997\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBarcode\u003c\/th\u003e\n\u003ctd\u003e5050028108283\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch2\u003eMore GU10 bulbs\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/energizer-led-gu10-bulb-360-lumen-daylight-a-rated\"\u003eEnergizer LED GU10 Bulb, 360 Lumen, Daylight, A Rated\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/sylvania-led-gu10-bulb-360-lumen-cool-white-a-rated\"\u003eSylvania LED GU10 Bulb, 360 Lumen, Cool White, A Rated\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/collections\/gu10-bulb\"\u003eShop the full GU10 Bulb collection\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JCB","offers":[{"title":"Default Title","offer_id":55610204422530,"sku":"362997","price":0.97,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0918\/5024\/4482\/files\/388658_20250218121219_1024.jpg?v=1756490833","url":"https:\/\/essentialsfix.co.uk\/products\/jcb-led-gu10-bulb-350-lumen-3000k-warm-white","provider":"Essentials Fix","version":"1.0","type":"link"}
