The GU10 twist-and-lock base fits standard mains-voltage spotlight housings without requiring a transformer, making it a direct replacement for 50W halogen GU10 bulbs.\u003c\/p\u003e\n\u003cp\u003eDesigned for fixed-output applications where dimming is not required, the bulb draws 4.9W on 230V mains and delivers a 100° beam angle that provides wide coverage from recessed ceiling downlights, track lighting heads and surface-mounted spotlight fittings. The 6500K colour temperature sits at the cool end of the spectrum, offering clarity and visibility for detail work, food preparation, reading technical documents and other tasks where accurate colour rendering and brightness matter.\u003c\/p\u003e\n\u003cp\u003eThe bulb measures 50mm in diameter and 57mm in height, matching the form factor of standard GU10 halogens so it fits flush within most downlight housings. At 30g, the bulb generates significantly less heat than the halogen equivalent, reducing the strain on ceiling insulation and fixture housings. The Energy Rating of G reflects the lower efficiency of compact LED formats compared to larger bulb types, but the bulb still uses 90% less energy than the 50W halogen 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\u003e50\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeight (mm)\u003c\/td\u003e\n\u003ctd\u003e57\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\u003e4.9W\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\u003eG\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eKelvin\u003c\/td\u003e\n\u003ctd\u003e6,500K\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColour Temperature\u003c\/td\u003e\n\u003ctd\u003eDaylight\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\u003e100\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. Attempting to use it with a dimmer switch will cause flickering or may damage the bulb or the dimmer. If dimming is required, select a bulb marked as dimmable.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is 6500K daylight suitable for?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e6500K sits at the cool, blue-white end of the spectrum and provides high-contrast, task-oriented light. It works well in kitchens, workshops, garages, offices and bathrooms where visibility and clarity are priorities. For relaxed or ambient spaces, a warmer 2700K-3000K bulb is generally preferred.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes it fit all GU10 downlight housings?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes. The 50mm diameter and 57mm height match standard GU10 halogen dimensions, so the bulb fits most recessed downlights, track heads and surface spotlights designed for GU10 fittings.
