The visible LED filaments inside a clear glass globe replicate the appearance of classic incandescent bulbs, making this suitable for exposed-bulb fittings where the bulb itself becomes part of the design.\u003c\/p\u003e\n\u003cp\u003eThe E27 Edison screw base fits standard UK and European lamp holders in table lamps, pendant shades, wall lights and ceiling fittings. The 60mm globe diameter and 109mm overall height suit most lampshades and open fittings without protruding or overwhelming the fitting itself. The non-dimmable design works on standard mains-switched circuits without requiring dimmer compatibility checks.\u003c\/p\u003e\n\u003cp\u003eThe 2700K colour temperature produces a warm, amber-tinted white light comparable to traditional tungsten bulbs, suited to living rooms, bedrooms and dining areas where warmer tones are preferred over cooler daylight whites. The 320-degree beam angle spreads light widely rather than focusing it in a narrow cone, giving even illumination across a room when used in ceiling or pendant fittings. The Energy Rating E reflects current LED efficiency standards, with the 4W consumption translating to approximately 90% lower running costs compared to the 40W incandescent bulb it replaces.\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\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\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\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. Installing it on a dimmer circuit may cause flickering, buzzing or premature failure.
