The candle profile suits decorative pendants, wall sconces, chandeliers and bedside table lamps where the bulb shape is visible.\u003c\/p\u003e\n\u003cp\u003eThe bulb is fully dimmable, allowing brightness adjustment from full 470-lumen output down to low ambient levels depending on the dimmer model fitted. The 4000K colour temperature sits between warm white and daylight, giving a neutral cool white that works in kitchens, bathrooms, hallways and workspaces where accurate colour rendering matters more than warmth. The B22 bayonet fitting is standard across UK domestic lighting and locks securely with a quarter-turn push-and-twist action.\u003c\/p\u003e\n\u003cp\u003eEnergizer rates this bulb at a 15-year lifespan based on average household use of 3 hours per day, reducing the frequency of replacements compared to incandescent or halogen equivalents. The E energy rating under current UK regulations reflects LED efficiency gains over older bulb technologies. The frosted candle envelope diffuses the LED chip evenly without glare, making the bulb comfortable to look at even in open fittings.\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\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 (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 compatible with all dimmer switches?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe bulb is designed to work with most LED-compatible dimmers. Older dimmer switches designed for incandescent bulbs may cause flickering or reduced dimming range. For best results, pair with a trailing-edge dimmer rated for LED loads.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does 4000K cool white look like compared to warm white?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e4000K sits between warm white (2700K-3000K) and daylight (5000K-6500K), producing a neutral white with a slight cool tint. It shows colours more accurately than warm white and works well in task areas like kitchens and bathrooms, but may feel less cosy than warm white in living rooms or bedrooms.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow long does the 15-year lifespan claim assume?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eEnergizer bases the 15-year rating on 3 hours of use per day. If used more intensively — for example 6 hours per day in a hallway or kitchen — the lifespan would reduce proportionally to around 7-8 years.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill this fit a standard UK ceiling pendant or wall light?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes.
