The LED consumes 3.6W on 230V mains and carries an E energy rating, running cooler than the halogen equivalent while producing the same focused light output. The bulb is non-dimmable.\u003c\/p\u003e\n\u003cp\u003eThis GU10 fits standard downlight housings, recessed ceiling fittings, track lighting systems and directional spotlights in kitchens, bathrooms, utility rooms and workspaces where task visibility matters. The 4000K colour temperature sits between warm white and daylight, providing neutral-toned light that renders colours accurately without the yellow cast of 2700K or the clinical brightness of 6500K. The 36° beam concentrates light onto worktops, sinks, counters and task areas rather than spreading it across the whole room.\u003c\/p\u003e\n\u003cp\u003eThe bulb measures 50mm diameter by 54mm height, matching the size of traditional halogen GU10s so it sits flush in existing fittings without protruding. Energizer rates the lifespan at 15 years based on average household use of 2.7 hours per day, which translates to approximately 15,000 hours before the LED degrades to 70% of its original output. The 50mm dichroic-style glass front disperses heat through the rear vents rather than projecting it forward into the room.\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\u003e50\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeight (mm)\u003c\/td\u003e\n\u003ctd\u003e54\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDepth (mm)\u003c\/td\u003e\n\u003ctd\u003e50\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWattage\u003c\/td\u003e\n\u003ctd\u003e3.6W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLumen\u003c\/td\u003e\n\u003ctd\u003e345\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLamp Shape\u003c\/td\u003e\n\u003ctd\u003eSpot\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLamp Base\u003c\/td\u003e\n\u003ctd\u003eGU10\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\u003e4,000K\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColour Temperature\u003c\/td\u003e\n\u003ctd\u003eCool 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\u003e36\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.
