The opal glass diffuser softens the light output and hides the internal LED filament array, making the bulb suitable for exposed-bulb fittings where the bulb itself is visible. Dimmable on most UK household dimmers, the bulb allows light levels to be adjusted from full 470 lumens down to a low ambient glow.\u003c\/p\u003e\n\u003cp\u003eDesigned as a direct replacement for 40W incandescent candle bulbs, this LED fits chandeliers, wall sconces, bedside table lamps and any decorative fitting with a B22 socket. The candle profile measures approximately 35mm diameter and 100mm height, matching the proportions of traditional candle bulbs so it sits correctly within lamp shades and decorative cages. The B22 bayonet fitting is the standard UK cap for most domestic light fittings.\u003c\/p\u003e\n\u003cp\u003eThe 4.2W draw reduces energy consumption by approximately 89% compared to the 40W incandescent it replaces, while the 15-year rated lifespan (based on 3 hours daily use) reduces replacement frequency. The opal glass finish provides even light distribution without visible LED hotspots, and the 2700K colour temperature matches the warm tone of traditional tungsten bulbs, avoiding the cooler blue-white cast of some LED replacements.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\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\u003e470lm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLamp Shape\u003c\/td\u003e\n\u003ctd\u003eCandle\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLamp Base\u003c\/td\u003e\n\u003ctd\u003eB22\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\u003e2,700K\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\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\/table\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eIs this bulb dimmable on all dimmers?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe bulb is designed to work with most leading-edge and trailing-edge dimmers fitted in UK homes. Dimmer compatibility varies by manufacturer and model, so if you experience flickering or the bulb does not dim smoothly, the dimmer switch may need upgrading to an LED-compatible model.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does the 15-year lifespan mean in practice?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe 15-year rating assumes 3 hours of use per day. If the bulb runs for longer daily periods, the lifespan shortens proportionally. At 6 hours per day, expect approximately 7-8 years. The lifespan refers to the point at which light output degrades to 70% of the original 470 lumens, not complete failure.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes the opal finish reduce brightness?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe opal glass diffuses the light to eliminate LED hotspots and provide even distribution, but it does absorb a small percentage of the total output. The 470 lumens rating accounts for this — it is the measured output through the opal glass, not the raw LED output before diffusion.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan this replace a 60W incandescent?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThis bulb replaces a 40W incandescent (approximately 470 lumens). For a 60W equivalent, look for LED candle bulbs rated at 7-9W delivering 650-800 lumens.
