The GLS (General Lighting Service) shape fits any standard lamp holder, from table lamps and ceiling pendants to wall lights and desk fittings.\u003c\/p\u003e\n\u003cp\u003eCool white 4000K output provides a crisp, neutral light suited to kitchens, bathrooms, home offices and workshops where task visibility and colour accuracy matter. The non-dimmable driver maintains steady output without flicker, making the bulb reliable for workspaces, utility rooms and commercial applications where consistent lighting is required throughout the day.\u003c\/p\u003e\n\u003cp\u003eThe 180-degree beam angle provides wide, even distribution across a room rather than a focused spot, so a single bulb can light a typical 3m x 3m kitchen or bathroom without dark corners. At 60mm diameter and 120mm height, the bulb fits compact lampshades and enclosed fittings where a larger bulb would not. Rated Energy Rating F under current UK labelling, the JCB bulb carries a 15-year lifespan claim based on typical domestic use patterns.\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\u003e0.07\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth (mm)\u003c\/td\u003e\n\u003ctd\u003e60\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeight (mm)\u003c\/td\u003e\n\u003ctd\u003e120\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDepth (mm)\u003c\/td\u003e\n\u003ctd\u003e70\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWattage\u003c\/td\u003e\n\u003ctd\u003e14W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLumen\u003c\/td\u003e\n\u003ctd\u003e1521\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLamp Shape\u003c\/td\u003e\n\u003ctd\u003eGLS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLamp Base\u003c\/td\u003e\n\u003ctd\u003eE27\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEnergy Rating\u003c\/td\u003e\n\u003ctd\u003eF\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eKelvin\u003c\/td\u003e\n\u003ctd\u003e4,000K\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColour Temperature\u003c\/td\u003e\n\u003ctd\u003eCool 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\u003e180\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. Installing it on a dimmer switch may cause flicker or damage to the bulb driver. If dimming is required, look for JCB dimmable LED bulbs in the same range.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's the difference between 4000K cool white and 3000K warm white?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e4000K produces a neutral, crisp white light similar to daylight through a window on an overcast day, suited to task-focused spaces like kitchens and offices. 3000K produces a warmer, softer white closer to traditional incandescent bulbs, better for living rooms and bedrooms. Choose based on the room's function.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill this fit in an enclosed fitting or lampshade?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes. The 60mm diameter and 120mm height fit most standard GLS lampshades and enclosed ceiling fittings. LED bulbs generate less heat than incandescent or halogen, making them safer in enclosed spaces.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow does 1521 lumens compare to older bulb ratings?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e1521 lumens is roughly equivalent to a 100W incandescent bulb. For comparison, a 60W incandescent produces around 800 lumens, and a 40W incandescent around 470 lumens. Lumens measure actual light output; wattage measures energy consumption.\u003c\/p\u003e","brand":"JCB","offers":[{"title":"Default Title","offer_id":46074104938763,"sku":"S12506","price":1.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/S12506_1_0c52aa64-a207-4f1b-829b-92ec1a1dfae6.jpg?v=1730311837","url":"https:\/\/niori.co.uk\/products\/jcb-14w-led-gls-bulb-e27-cool-white-4000k-non-dimmable-1521lm","provider":"Niori","version":"1.0","type":"link"}
