The bulb offers a direct replacement for traditional 40W incandescent GLS bulbs, fitting the same lampholders and providing comparable brightness at 88% lower energy consumption.\u003c\/p\u003e\n\u003cp\u003eDesigned for general lighting in homes, offices and hospitality settings, the bulb suits ceiling pendants, table lamps, desk lamps and wall-mounted fittings where an E27 base is standard. The 3000K colour temperature produces a soft warm white tone that works well in living rooms, bedrooms, dining rooms and hallways where a relaxed atmosphere is preferred over the cooler white of task lighting. The bulb is non-dimmable and provides consistent, flicker-free output on standard UK 230V circuits.\u003c\/p\u003e\n\u003cp\u003eThe GLS (General Lamp Service) shape is the classic pear-shaped bulb profile with a 60mm diameter and 110mm total height. The frosted white finish diffuses the internal LED array evenly, eliminating visible hotspots or striping when viewed directly. JCB rates the bulb for up to 10 years of typical domestic use, based on an average 2.7 hours per day operating period. The 180-degree beam angle distributes light broadly, making the bulb suitable for open-shade fittings and exposed pendants where wide dispersion is needed.\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\u003e0.04\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\u003e110\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\u003e4.9W\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\u003eE27\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\u003e3,000K\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\u003e180\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\u003eWhat incandescent wattage does this replace?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThis 4.9W LED bulb replaces a traditional 40W incandescent GLS bulb, delivering 470 lumens at 88% lower energy draw.
