Each bulb is rated to replace a traditional 50W halogen spotlight while consuming 91% less power. The twin pack suits kitchens, bathrooms, hallways and living rooms fitted with GU10 downlights or track lighting.\u003c\/p\u003e\n\u003cp\u003eThe 3000K colour temperature delivers a warm white tone that sits between soft yellow (2700K) and neutral white (4000K), making it suitable for general residential lighting where a cosy but functional light is needed. The 345-lumen output provides adequate brightness for most downlight applications spaced 1-1.5m apart in a standard 2.4m ceiling height room. The bulbs are non-dimmable and run on 230V mains without requiring a transformer.\u003c\/p\u003e\n\u003cp\u003eEnergizer rates these GU10 LEDs at a 10-year lifespan based on 2.7 hours daily use, equating to approximately 10,000 operating hours. The 50mm diameter and 54mm height fit standard GU10 downlight housings without projection beyond the ceiling line. The bulbs operate without flicker once warmed up and produce minimal heat compared to halogen equivalents, reducing cooling load in enclosed downlight fittings.\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\u003e0.06\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\u003e4.2W\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\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\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 wattage halogen bulb does this replace?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe 4.2W LED bulb is rated to replace a 50W halogen GU10 in terms of light output. The 345-lumen output is comparable to most 50W halogen spotlights, though the beam pattern may differ slightly depending on the reflector design.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAre these bulbs dimmable?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. These GU10 LEDs are non-dimmable and should only be used on standard on\/off circuits.
