It draws 4.2W and gives 470 lumens at 6500K, a daylight white that reads crisp and slightly blue next to the yellower light of an older filament bulb. The pack rates it as a 40W replacement. The frosted envelope sits over the diode so the bulb reads as a plain white ball rather than a cluster of bright points, which matters in an open shade or a clear glass fitting where the lamp itself is on show.\u003c\/p\u003e\n\u003cp\u003eA golf ball is the shape to reach for when the fitting is small and a standard GLS bulb would sit proud of the shade. It suits bedside lamps, small table lamps, wall lights and multi-arm pendants where several bulbs sit close together and bulk is the deciding factor. The 6500K colour temperature pushes it towards places where you want to see clearly rather than wind down: a kitchen, a utility room, a home office, a hobby bench or a workshop lamp. In a bedroom it will feel bright and awake, so if you want a softer glow after dark, pick a 2700K bulb instead.\u003c\/p\u003e\n\u003cp\u003eDimming needs a dimmer switch built for LED loads. Older mains dimmers made for filament bulbs often have a minimum wattage well above 4.2W, and a single lamp of this size may flicker or refuse to strike on one. The pack prints a 25,000 hour life and an instant start, so there is no warm-up before full brightness. The energy label carries class E, and the IP20 rating means dry indoor fittings only. One unit is one bulb, with a minimum order of 10 in multiples of 10. We stock the same 4.2W and 470lm lamp as a B15 candle in warm white 2700K.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eFitting\u003c\/td\u003e\n\u003ctd\u003eE27 (ES) screw\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShape\u003c\/td\u003e\n\u003ctd\u003eGolf ball, frosted\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTechnology\u003c\/td\u003e\n\u003ctd\u003eLED\u003c\/td\u003e\n\u003c\/tr\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\u003eBrightness\u003c\/td\u003e\n\u003ctd\u003e470lm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEquivalent\u003c\/td\u003e\n\u003ctd\u003e40W, as printed on the pack\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColour temperature\u003c\/td\u003e\n\u003ctd\u003e6500K, daylight\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBeam angle\u003c\/td\u003e\n\u003ctd\u003e240 degrees\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\u003eIP rating\u003c\/td\u003e\n\u003ctd\u003eIP20\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\u003eLifespan as printed\u003c\/td\u003e\n\u003ctd\u003e25,000 hours, as printed on the pack\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSold as\u003c\/td\u003e\n\u003ctd\u003eSingle bulb\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMinimum order\u003c\/td\u003e\n\u003ctd\u003e10, sold in multiples of 10\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eHow do I know my lamp takes an E27 cap?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eE27 is the larger screw cap, roughly 27mm across the thread.
