The B15 small bayonet cap fits UK decorative light fittings including wall lights, chandeliers and candelabra-style table lamps where the smaller 15mm base diameter is required over the standard B22.\u003c\/p\u003e\n\u003cp\u003eRated at 4000K, the bulb produces a cool white light that sits between warm white (2700K-3000K) and daylight white (5000K+), offering clearer colour rendering than warm tones without the clinical feel of daylight bulbs. The dimmable design works with most leading-edge and trailing-edge dimmer switches, allowing light levels to be reduced for ambient lighting or increased for task lighting as needed.\u003c\/p\u003e\n\u003cp\u003eAt 5W consumption the bulb replaces traditional 40W incandescent candles, reducing energy use by approximately 87% while maintaining comparable light output. The E energy rating under current EU\/UK regulations reflects the efficiency gains LED technology delivers over older bulb types. Energizer rates the bulb for a 15-year average lifespan based on typical domestic use patterns of 2.7 hours per day.\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\u003e5W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLumen\u003c\/td\u003e\n\u003ctd\u003e550lm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLamp Shape\u003c\/td\u003e\n\u003ctd\u003eFilament\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLamp Base\u003c\/td\u003e\n\u003ctd\u003eB15\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\u003eWhat is a B15 bulb base?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eB15 is a small bayonet cap with a 15mm diameter base, also called SBC.

The bulb is rated as dimmable and works with most modern leading-edge and trailing-edge dimmer switches. Compatibility can vary by dimmer model, so if flickering or limited dimming range occurs, check that the dimmer is rated for LED loads and that the total wattage of bulbs on the circuit meets the dimmer's minimum load requirement.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is 4000K cool white used for?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e4000K sits between warm white and daylight white, producing a neutral, slightly crisp light that improves colour clarity compared to warmer tones.
