The 4W LED replaces a traditional 40W incandescent golf ball bulb, fitting an E27 Edison screw base and drawing less than a tenth of the power while producing comparable light output.\u003c\/p\u003e\n\u003cp\u003eDesigned for table lamps, wall sconces, pendant fittings and decorative ceiling fixtures where the bulb is visible or partially exposed, the clear glass and filament styling give a traditional incandescent appearance when lit. The golf ball shape suits compact lampshades and smaller apertures where a standard A60 bulb would be too large. The non-dimmable circuitry is optimised for mains switching only — pairing with a dimmer may cause flicker or damage the bulb.\u003c\/p\u003e\n\u003cp\u003eThe 2700K colour temperature sits in the warm white range, producing light with a slight amber cast that pairs well with wood, brass and warm-toned interiors. The rated 15-year lifespan assumes 3 hours daily use and reflects typical LED longevity in domestic applications. The Energy Rating E indicates mid-range efficiency within current LED classifications — suitable for decorative applications where the visible filament justifies slightly lower efficiency than opaque LED bulbs.\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\u003e5W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLumen\u003c\/td\u003e\n\u003ctd\u003e470LM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLamp Shape\u003c\/td\u003e\n\u003ctd\u003eGolf\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\u003eE\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\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\u003eCan this bulb be used with a dimmer switch?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. The bulb is non-dimmable and should only be used with standard on\/off switching.

For context, a 60W incandescent produces around 700-800 lumens, and a 25W incandescent around 220-250 lumens.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does the 15-year lifespan mean in practice?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe 15-year rating assumes the bulb runs for approximately 3 hours per day. If used more heavily — for example 6 hours daily in a living room table lamp — the lifespan would halve to around 7-8 years.\u003c\/p\u003e","brand":"Energizer","offers":[{"title":"Default Title","offer_id":46075007959307,"sku":"S29791","price":1.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/S29791_1_24a97706-67f9-4500-9785-4c49f6a1895b.jpg?v=1730316661","url":"https:\/\/niori.co.uk\/products\/energizer-4w-led-golf-ball-filament-bulb-e27-2700k-non-dimmable","provider":"Niori","version":"1.0","type":"link"}
