The bulb draws 5W on 230V mains as a direct replacement for 40W incandescent golf balls, cutting energy consumption by 87% while maintaining equivalent light output.\u003c\/p\u003e\n\u003cp\u003eDesigned for smaller fittings where a standard GLS bulb would be too large, the compact golf ball profile suits chandeliers with multiple arms, bedside table lamps, wall sconces and decorative pendants with visible bulbs. The dimmable function works with most leading-edge and trailing-edge dimmer switches, allowing brightness to be adjusted from full 550-lumen output down to a low-level glow for evening ambience. The B15 cap is the smaller UK bayonet fitting, commonly found in older British light fittings and period-style reproductions.\u003c\/p\u003e\n\u003cp\u003eThe filament-style LED strips inside the bulb mimic the appearance of traditional carbon filament bulbs when lit, giving a warm glow through the clear glass without the fragility or short lifespan of genuine incandescent filaments. The 2700K colour temperature produces a warm white tone similar to halogen, avoiding the cooler blue-white cast of higher-Kelvin LEDs. Energizer rates the bulb for a 15-year lifespan based on average domestic use, significantly outlasting both halogen and incandescent equivalents.\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\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\u003eGolf\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\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\u003eWhat fitting does the B15 cap fit?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe B15 is the small bayonet cap, measuring 15mm across the base pins.
