The exposed filament design recreates the look of traditional tungsten bulbs while consuming 90% less energy than the 40W incandescent bulbs it replaces.\u003c\/p\u003e\n\u003cp\u003eDesigned for standard UK bayonet fittings in table lamps, floor lamps, ceiling pendants and wall lights, the bulb fits anywhere a traditional GLS shape works. The 2700K colour temperature produces a warm amber-toned light suited to living rooms, bedrooms and hallways where a cosy atmosphere is needed rather than bright task lighting. The 320-degree beam angle provides wide light distribution without the directional hotspots of spotlight-style LEDs.\u003c\/p\u003e\n\u003cp\u003eAt 60mm diameter and 109mm height, the bulb matches the proportions of a standard GLS shape and sits comfortably in most decorative lampshades without protruding. The clear glass envelope shows the LED filament strips when the bulb is off, giving a vintage aesthetic that works in both traditional and industrial-style fittings. Energizer rates this bulb for a 15-year lifespan based on average household use, reducing the frequency of replacements compared to halogen or incandescent alternatives.\u003c\/p\u003e\n\u003cp\u003eThe bulb carries an Energy Rating of E under current UK labelling, reflecting its consumption relative to newer high-efficiency LED models, but still represents a substantial saving over the incandescent technology it replaces. Non-dimmable operation means the bulb should not be paired with dimmer switches — use only on standard on-off circuits.\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\u003e0.03\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\u003e4W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLumen\u003c\/td\u003e\n\u003ctd\u003e470\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\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\u003eBeam Angle\u003c\/td\u003e\n\u003ctd\u003e320\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. This is a non-dimmable LED bulb and must only be used on standard on-off switching circuits.
