The dome is frosted, so light leaves it spread rather than as a hard point, and the LED inside gives 470 lumens at 6500K. That is daylight white, the crispest of the white tones, with a cool edge rather than the yellow of a filament. The box front prints 5W and a 40W replacement, while the detailed specification gives the draw as 4.2W.\u003c\/p\u003e\n\u003cp\u003eDaylight white at this brightness is a working light rather than a restful one. It suits a desk lamp, a reading light, a kitchen or utility fitting, a garage inspection lamp or a workshop pendant, anywhere you need to see detail and judge colour properly. It is less suited to a sitting room in the evening, where 2700K warm white is the usual pick. The 240 degree spread matters in multi-arm fittings and open-ended shades: light carries sideways and upwards as well as down, so a fitting lights the room evenly rather than throwing one pool downwards. IP20 is the ordinary indoor rating, so keep it to dry domestic fittings.\u003c\/p\u003e\n\u003cp\u003eIt dims, which is worth knowing because many small LED lamps do not, and it wants a dimmer rated for LED loads. A single 4.2W lamp draws very little, and an older dimmer built for 40W filament bulbs may need more load than one bulb gives before it runs smoothly. The pack states a 25,000 hour life and instant start, so there is no warm-up. The energy rating is E on the current label scale. One unit is a single bulb and the minimum order is 10, sold in multiples of 10. We also stock a B15 candle bulb at the same 470 lumens 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\u003eB15 small bayonet cap (SBC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShape\u003c\/td\u003e\n\u003ctd\u003eGolf\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 (the retail pack prints 5W)\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 tell a B15 cap from a B22 or an E14?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eB15 is a bayonet cap with two side pins, like a B22, but noticeably narrower at 15mm across.

Use a dimmer designed for LED loads, and bear in mind that one 4.2W lamp on an old filament dimmer may sit below that dimmer's minimum load and flicker.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does 6500K daylight white actually look like?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eIt is a cool, crisp white with a slight blue cast, close to midday light.
