The E27 screw base fits standard UK lampholders, and the bulb outputs 440 lumens at 2200K, delivering a warm amber glow closer to candlelight than standard warm white bulbs.\u003c\/p\u003e\n\u003cp\u003eDesigned for decorative and ambient applications rather than task lighting, this bulb suits exposed-filament pendants, table lamps with clear glass shades, wall sconces and vintage-style industrial fixtures where the bulb itself is visible. The 2200K colour temperature produces a noticeably warmer, more golden tone than typical 2700K-3000K warm white LEDs, making it better suited to evening and hospitality settings where soft, low-intensity light creates atmosphere.\u003c\/p\u003e\n\u003cp\u003eThe gold tint on the glass envelope softens the light output and gives the bulb a bronze appearance when switched off, contrasting with clear or frosted glass bulbs in the same fixture. At 60mm diameter and 117mm height, the GLS profile matches the size of a standard household bulb. The 4W power draw replaces a 35W incandescent while drawing 88% less energy, and the non-dimmable driver keeps the unit cost down for applications where dimming is not required.\u003c\/p\u003e\n\u003cp\u003eThe 320-degree beam angle provides near-omnidirectional light distribution typical of GLS bulbs. The Energy Rating of E reflects current UK bulb efficiency standards — this rating sits in the middle of the post-2021 LED scale, which runs from A (most efficient) to G. The visible filament design means the bulb performs best in fixtures where it can be seen, rather than hidden inside a closed shade or recessed fitting.\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\u003e60\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeight (mm)\u003c\/td\u003e\n\u003ctd\u003e117128\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\u003e4W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLumen\u003c\/td\u003e\n\u003ctd\u003e440\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\u003e2,200K\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\u003e320\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 colour temperature is 2200K compared to standard warm white?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eAt 2200K this bulb produces a noticeably warmer, more amber tone than typical warm white LEDs, which sit between 2700K-3000K. The light is closer to candlelight or early evening sunset, making it well-suited to atmospheric and decorative applications rather than functional task lighting.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs this bulb suitable for reading or task lighting?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNot really. The 440 lumens output and 2200K colour temperature are designed for ambient and decorative use. For reading or desk work, a higher lumen output and a cooler colour temperature around 3000K-4000K would be more appropriate.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan this bulb be used in enclosed fittings?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eCheck the fitting for ventilation. Some fully-enclosed glass or metal shades can cause LEDs to overheat if there is no airflow. This bulb performs best in open or semi-open fixtures where the filament can be seen and air can circulate.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does the gold tint do to the light output?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe gold-tinted glass filters the light, reducing overall brightness slightly and adding warmth to the colour tone. When the bulb is off, the gold tint gives the glass a bronze appearance, which is decorative in exposed-filament fixtures.\u003c\/p\u003e","brand":"Energizer","offers":[{"title":"Default Title","offer_id":46074112442635,"sku":"S12860","price":1.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/S12860_1_34146480-4d80-4258-9f30-24c88cde044d.jpg?v=1730311888","url":"https:\/\/niori.co.uk\/products\/energizer-4w-led-gls-bulb-e27-gold-filament-2200k-warm-white-non-dimmable","provider":"Niori","version":"1.0","type":"link"}
