It takes a B22 fitting, the push-and-twist bayonet cap found on most British ceiling pendants and table lamps, and it draws 13W to give 1521 lumens. The pack rates that as a 100W replacement, which puts it at the bright end of what a standard household bulb gives. A switch on the body of the lamp moves it between 2700K warm white, 4000K cool white and 6500K daylight, and the bulb is dimmable. The energy class printed on the pack is E.\u003c\/p\u003e\n\u003cp\u003eOne bulb covering three colour temperatures is useful where the same room does two jobs. In a living room, 2700K gives the soft yellow light people expect from an evening lamp; 4000K is a cleaner, more neutral white that suits a kitchen, a landing or a home office; 6500K is a crisp daylight tone that helps with close work such as sewing, model making or reading small print. Because the GLS shape is the familiar pear-shaped household bulb, it sits properly under a shade and behaves like the bulb it replaces rather than making you rethink the fitting.\u003c\/p\u003e\n\u003cp\u003eThe colour is chosen on the bulb itself rather than at the wall, so set it before you fit the shade and let the wall switch carry on doing its usual job. Dimming needs a dimmer rated for LED loads; older mains dimmers built for filament bulbs often hum or flicker with a low wattage lamp. The pack prints a 15,000 hour lifespan, described there as 15 years. Each box holds one bulb, and the minimum order is 12, sold in multiples of 12, which suits anyone fitting out a whole house or keeping a few spares in the cupboard.\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\u003eB22 bayonet cap (BC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShape\u003c\/td\u003e\n\u003ctd\u003eGLS\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\u003e13W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrightness\u003c\/td\u003e\n\u003ctd\u003e1521lm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEquivalent\u003c\/td\u003e\n\u003ctd\u003e100W, as printed on the pack\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColour temperature\u003c\/td\u003e\n\u003ctd\u003e2700K, 4000K or 6500K, chosen on the lamp switch\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimmable\u003c\/td\u003e\n\u003ctd\u003eYes, as printed on the pack\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIP rating\u003c\/td\u003e\n\u003ctd\u003eNot stated by the manufacturer\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEnergy rating\u003c\/td\u003e\n\u003ctd\u003eE, as printed on the pack\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLifespan as printed\u003c\/td\u003e\n\u003ctd\u003e15,000 hours, printed on the pack as a 15 year lifespan\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSold as\u003c\/td\u003e\n\u003ctd\u003eSingle bulb, box of 1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMinimum order\u003c\/td\u003e\n\u003ctd\u003e12, sold in multiples of 12\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 tell whether my lamp takes a B22 cap?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eLook at the base of the old bulb.
