The E14 small Edison screw base fits chandelier-style fittings, wall lights and table lamps where the bulb is visible. The 2700K warm white output delivers 490lm through a 310-degree beam angle, providing ambient light rather than focused task light.\u003c\/p\u003e\n\u003cp\u003eDesigned for decorative fittings where the bulb itself is part of the aesthetic, the clear glass shell shows four LED filament strips arranged in a traditional tungsten-style layout. The 45mm diameter and 78mm overall height fit standard candelabra fittings, chandelier arms and compact table lamp shades without overhang. The bulb is dimmable when paired with compatible trailing edge dimmers, allowing output to be reduced for evening ambience or increased for functional light.\u003c\/p\u003e\n\u003cp\u003eThe filament construction gives this bulb a higher efficacy of 132.2lm\/W compared to older LED designs, meaning it produces more light per watt consumed. The L70B50 rating of 15,000 hours indicates the bulb will retain at least 70% of its initial brightness after 15,000 hours of use under typical operating conditions. The warm 2700K colour temperature matches the glow of traditional incandescent bulbs, sitting at the warmer end of the white spectrum and pairing well with brass, copper and timber finishes.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiameter\u003c\/td\u003e\n\u003ctd\u003e45 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeight\u003c\/td\u003e\n\u003ctd\u003e78 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConstruction\u003c\/td\u003e\n\u003ctd\u003eGlass\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIP Rating\u003c\/td\u003e\n\u003ctd\u003eIP20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePrimary Voltage\u003c\/td\u003e\n\u003ctd\u003e230V 50Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiffuser\u003c\/td\u003e\n\u003ctd\u003eClear\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLamp Technology\u003c\/td\u003e\n\u003ctd\u003eLED Filament\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLamp Base\u003c\/td\u003e\n\u003ctd\u003eE14\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimmable\u003c\/td\u003e\n\u003ctd\u003eYes*\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eL70B50\u003c\/td\u003e\n\u003ctd\u003e15000\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEnergy Rating (Class) post 2021 SLR\u003c\/td\u003e\n\u003ctd\u003eE\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBeam Angle\u003c\/td\u003e\n\u003ctd\u003e310\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCCT\u003c\/td\u003e\n\u003ctd\u003e2700 K\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLight Colour\u003c\/td\u003e\n\u003ctd\u003eWarm White\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLumens\u003c\/td\u003e\n\u003ctd\u003e490 lm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWattage\u003c\/td\u003e\n\u003ctd\u003e4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEfficacy\u003c\/td\u003e\n\u003ctd\u003e132.2 lm\/W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCRI\u003c\/td\u003e\n\u003ctd\u003e\u0026gt;80\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003e2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch5\u003eDownloads\u003c\/h5\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/products_4970202_datasheet.pdf\" target=\"_blank\"\u003eProduct Specification Sheet\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eIs this bulb dimmable?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes, the bulb is dimmable when paired with compatible trailing edge dimmers. Dimmer compatibility varies by manufacturer and model, so verify your dimmer supports LED filament bulbs before installation. Leading edge dimmers designed for older incandescent bulbs may cause flickering or reduced dimming range.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat fitting does it replace?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThis 4W LED bulb replaces a traditional 40W incandescent golf ball bulb in any E14 (small Edison screw) fitting. The 490lm output provides comparable brightness to a 40W tungsten bulb while consuming 90% less energy.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhere is this bulb typically used?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe E14 golf ball format suits chandelier arms, decorative wall lights, bedside table lamps and any fitting where the bulb is visible and smaller than a standard A60 shape. The clear glass and exposed filament design works best in fittings where the bulb itself contributes to the aesthetic rather than being hidden inside a shade.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does the 2700K colour temperature mean?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e2700K sits at the warm end of the white light spectrum, producing a soft yellow-white glow similar to traditional incandescent bulbs.
