The 2700K warm white colour temperature produces a soft yellow-toned light comparable to traditional tungsten incandescent bulbs, making it suitable for living rooms, bedrooms and dining areas where warm ambient lighting is preferred.\u003c\/p\u003e\n\u003cp\u003eDesigned as a direct replacement for 100W incandescent bulbs, this LED consumes 86.5% less energy whilst producing equivalent light output. The E27 screw base fits standard UK and European lamp holders in table lamps, floor lamps, pendant fittings and ceiling fixtures. The bulb is non-dimmable and should be paired only with standard on\/off switches — installing it in a dimmer circuit may cause flickering or premature failure.\u003c\/p\u003e\n\u003cp\u003eThe 240-degree beam angle provides wide light distribution across a room rather than focused directional output, making it appropriate for general ambient lighting rather than task lighting. At 60mm diameter and 122mm height, the bulb fits most standard lamp shades and enclosed fittings. Energizer rates the lifespan at 15 years based on average daily use of 2.7 hours, which translates to approximately 15,000 operating hours before output drops below 70% of initial brightness.\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\u003e0.07\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\u003e122\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\u003e13.5W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLumen\u003c\/td\u003e\n\u003ctd\u003e1521\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\u003e240\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 with standard on\/off switches.

If dimming is required, search for Energizer's dimmable LED range.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does the 15-year lifespan mean in practice?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe 15-year rating assumes the bulb operates for an average of 2.7 hours per day, totalling approximately 15,000 hours of use. After this period, the bulb will still function but its light output will have degraded to around 70% of the initial 1521 lumens.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill this fit my existing lamp?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eIf your lamp or fitting has an E27 (Edison screw) socket, yes. The E27 base is the standard large screw fitting used across the UK and Europe. The bulb measures 60mm wide by 122mm tall, so check shade clearances if fitting into enclosed or narrow lamp shades.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow does 2700K compare to other colour temperatures?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e2700K produces a warm yellow-white light similar to traditional incandescent bulbs, creating a cosy atmosphere in living spaces.
