The classic GLS (general lighting service) shape measures approximately 60mm diameter and 110mm height, matching the form factor of traditional incandescent bulbs. The 9.5W power draw replaces a 75W incandescent equivalent, reducing energy consumption by around 87% for the same lumen output.\u003c\/p\u003e\n\u003cp\u003eDesigned for task-oriented spaces where neutral, bright light supports visibility and concentration, the 4000K colour temperature suits kitchens, utility rooms, garages, home offices and hallways. The cool white tone falls between warm yellow (2700K-3000K) and clinical daylight (5000K-6500K), providing clarity without the starkness of higher colour temperatures. The bulb operates on 230V mains and delivers instant-on brightness without warm-up delay.\u003c\/p\u003e\n\u003cp\u003eThe bulb is non-dimmable and carries an E energy rating under current UK labelling regulations. Energizer rates the LED for a 15-year lifespan based on average household use of 2.7 hours per day, equating to approximately 15,000 switching cycles. The frosted glass diffuser spreads light evenly across a 240-degree beam angle, reducing glare and hot spots compared to clear LED filaments.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eWattage\u003c\/td\u003e\n\u003ctd\u003e9.5W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLumen\u003c\/td\u003e\n\u003ctd\u003e1060lm\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 (New Regs)\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\u003eYes\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\/tbody\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. Despite the specification table indicating 'Yes', the product title and URL confirm this is a non-dimmable bulb.

Actual longevity depends on switching frequency, ambient temperature and fixture ventilation. LEDs degrade gradually rather than failing instantly, so expect a slow reduction in brightness over the rated period.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I use this in an enclosed fitting?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eMost GLS LED bulbs tolerate enclosed fittings, but check that the fitting allows some airflow. Fully sealed, poorly ventilated enclosures can shorten LED lifespan due to heat buildup. If in doubt, leave the fitting slightly open or choose a bulb rated explicitly for enclosed use.\u003c\/p\u003e","brand":"Energizer","offers":[{"title":"Default Title","offer_id":51783313981707,"sku":"S30646","price":1.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/S30646_1_7fcc441c-8e6d-4d8c-a7d2-bce129566558.jpg?v=1750876551","url":"https:\/\/niori.co.uk\/products\/energizer-9-5w-e27-gls-led-bulb-cool-white-4000k-non-dimmable","provider":"Niori","version":"1.0","type":"link"}
