The standard E27 Edison screw base fits most table lamps, pendant fittings and ceiling lights designed for traditional bulbs, and the classic GLS (general lighting service) shape ensures it sits correctly within shades and diffusers designed for incandescent bulbs.\u003c\/p\u003e\n\u003cp\u003eDesigned for utility areas, garages, workshops, kitchens and bathrooms where bright, cool-toned light is needed, the 6500K colour temperature mimics natural daylight and provides high contrast for task work. The 180-degree beam angle spreads light evenly across a room rather than concentrating it in a spotlight effect, making the bulb suitable for general ambient lighting as well as task applications. The bulb is non-dimmable and operates on standard 220-240V mains.\u003c\/p\u003e\n\u003cp\u003eAt 110mm tall and 60mm diameter, the bulb matches the size of a traditional 40W GLS incandescent, so it fits within the same physical envelope in existing lamp holders and shades. The frosted polycarbonate outer diffuses the LED elements inside, giving a uniform glow rather than visible point-sources. JCB rates the bulb for up to 10,000 hours of use, which translates to approximately 10 years at 3 hours per day.\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\u003e0.04\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\u003e110\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\u003e4.9W\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\u003eF\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\u003e180\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 is 6500K daylight white used for?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e6500K is a cool, blue-toned white that mimics natural daylight at midday. It provides high contrast and colour accuracy, making it suitable for task areas like workshops, garages, kitchens and bathrooms where bright, clear light is needed.
