The bulbs use standard GLS (General Lighting Service) shape with a 60mm diameter and 109mm height, fitting traditional lampholders across ceiling pendants, table lamps, floor lamps and wall lights. Each bulb replaces a 60W incandescent equivalent while drawing just 8.5W.\u003c\/p\u003e\n\u003cp\u003eDesigned for general ambient lighting in living rooms, bedrooms, hallways and dining areas, the bulbs provide non-dimmable output with a 240-degree beam angle that spreads light widely across a room. The B22 bayonet fitting is the UK standard for most domestic lampholders, making installation straightforward with a push-and-twist motion. The 3000K colour temperature sits in the warm white spectrum, producing a yellow-toned light comparable to traditional incandescent bulbs rather than the cooler blue-white of daylight LEDs.\u003c\/p\u003e\n\u003cp\u003eEach bulb carries an F energy rating under the 2021 EU energy label scale, which recalibrated ratings to account for LED improvements and set stricter thresholds than the previous A++ to E scale. The 806-lumen output provides sufficient brightness for general room lighting in spaces up to 15-20 square metres, with multiple bulbs needed for larger open-plan areas. The non-dimmable driver circuit inside each bulb means they are not compatible with dimmer switches and will either flicker or fail if connected to dimming circuits.\u003c\/p\u003e\n\u003cp\u003eThe four-pack format suits whole-room re-lamping or replacing multiple bulbs across a property at once, reducing the per-bulb cost compared to buying singles. Energizer rates these bulbs for approximately 15,000 hours of use, which translates to roughly 13-15 years at three hours per day.\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\u003e0.11\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\u003e109\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDepth (mm)\u003c\/td\u003e\n\u003ctd\u003e60\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWattage\u003c\/td\u003e\n\u003ctd\u003e8.5W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLumen\u003c\/td\u003e\n\u003ctd\u003e806\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\u003eB22\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\u003e2,700K\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\u003e240\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\u003eAre these bulbs dimmable?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. These are non-dimmable LED bulbs and must not be fitted to circuits controlled by dimmer switches.

This is warmer and more amber than daylight white LEDs rated at 4000K or above.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow many bulbs do I need for a room?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eEach bulb delivers 806 lumens. A typical living room of 15-20 square metres needs approximately 1,500-3,000 lumens total, so two to four of these bulbs would be appropriate depending on ceiling height and fixture type.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does the F energy rating mean?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe F rating is on the 2021 EU energy label scale, which recalibrated ratings to make A and B grades harder to achieve. An F-rated LED is still far more efficient than an incandescent bulb and uses 85% less energy than a 60W equivalent.\u003c\/p\u003e","brand":"Energizer","offers":[{"title":"Default Title","offer_id":46074202095883,"sku":"S14056","price":2.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/S14056_1_188b0ce1-2ebb-423e-9e76-765b2c3afdad.jpg?v=1730312318","url":"https:\/\/niori.co.uk\/products\/energizer-8-5w-led-gls-bulb-b22-warm-white-3000k-non-dimmable-4-pack","provider":"Niori","version":"1.0","type":"link"}
