The GLS (General Lighting Service) shape measures 60mm diameter by 128mm height, fitting standard table lamps, pendants, and ceiling fixtures that accept E27 Edison screw bulbs.\u003c\/p\u003e\n\u003cp\u003eDesigned for residential lighting in living rooms, bedrooms, hallways and dining areas where warm ambient light is preferred over task lighting, the 2700K colour temperature sits at the warmer end of the white spectrum and pairs well with traditional and contemporary interiors. The bulb is non-dimmable and delivers steady output without flicker when powered from standard 230V UK mains.\u003c\/p\u003e\n\u003cp\u003eThe bulb carries an Energy Rating of E and a claimed 15-year lifespan under typical residential use patterns, which Energizer bases on an average of 2.7 hours daily operation. The frosted glass envelope diffuses the internal LED filament to prevent visible hot spots and provides a soft, even light distribution similar to classic incandescent bulbs.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\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\u003e128\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\u003e4.2W\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\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\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\u003eIs this bulb dimmable?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. This is a non-dimmable LED bulb and should not be used with dimmer switches, as doing so can cause flickering, reduced lifespan, or damage to the bulb.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does 2700K warm white look like?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e2700K produces a warm, slightly yellow-toned white light similar to traditional incandescent bulbs.
