It draws 4W and puts out 310 lumens at 3000K, a warm white that sits comfortably in the evening without tipping into amber. The light is directional, so it lays down a defined pool where you aim it instead of washing the whole room. There is no dimming, so it belongs on a plain switch.\u003c\/p\u003e\u003cp\u003eWe reach for lamps of this size in kitchen spotlight bars, over worktops and inside glazed display cabinets, and in compact ceiling fittings where a full-length GU10 would look bulky. The tight throw suits picking out pictures, shelves and a well-placed plant, while the warm tone keeps sitting rooms and bedrooms restful once the sun has gone. If you are relamping a whole run of spots, we would take them all at once: mixed batches and mixed colour temperatures announce themselves the moment they go up on a white ceiling. Anyone after a cooler, whiter light is better served elsewhere in the range.\u003c\/p\u003e\u003cp\u003eThe opal white face keeps things quiet in open fittings where the lamp itself is in view. Dust is the only real enemy here: let it cool, then wipe the face with a dry cloth so nothing muddies the beam. It carries a three year warranty, and it is meant for dry indoor rooms running on an ordinary household supply. Alongside it the range runs to slim GX53 discs, small G4 capsules and E27 globes, and there is a corn-type GU10 as well if you would rather have light spreading in every direction than a focused pool. The LEDs are built in, so there is nothing to replace inside it.\u003c\/p\u003e\u003ch5\u003eSpecification\u003c\/h5\u003e\u003ctable class=\"spec_table\"\u003e\u003ctbody\u003e\n\n\u003ctr\u003e\n\u003ctd\u003eColour\u003c\/td\u003e\n\u003ctd\u003eOpal White\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.02KG\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiameter\u003c\/td\u003e\n\u003ctd\u003e35mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeight\u003c\/td\u003e\n\u003ctd\u003e48mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterials Used\u003c\/td\u003e\n\u003ctd\u003eAluminium, Plastic\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEnergy Class\u003c\/td\u003e\n\u003ctd\u003eA+\u003c\/td\u003e\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\u003ctd\u003eMax Energy Class\u003c\/td\u003e\n\u003ctd\u003eA+\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMin Energy Class\u003c\/td\u003e\n\u003ctd\u003eA+\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLamp Cap\u003c\/td\u003e\n\u003ctd\u003eGU11\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRecommended Lamp\u003c\/td\u003e\n\u003ctd\u003eLED (35mm Reflector)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Wattage\u003c\/td\u003e\n\u003ctd\u003e4W\u003c\/td\u003e\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\u003ctd\u003eColour Temperature\u003c\/td\u003e\n\u003ctd\u003e3000K Warm White (±5%)\u003c\/td\u003e\n\u003c\/tr\u003e\n\n\n\u003ctr\u003e\n\u003ctd\u003eLED Power\u003c\/td\u003e\n\u003ctd\u003e4W (±5%)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLumens per Watt (lm\/W)\u003c\/td\u003e\n\u003ctd\u003e78lm\/W (±5%)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBeam Angle\u003c\/td\u003e\n\u003ctd\u003e38°\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSystem Flux\u003c\/td\u003e\n\u003ctd\u003e310lm (±5%)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCRI\u003c\/td\u003e\n\u003ctd\u003e\u0026gt;80\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLight Distribution\u003c\/td\u003e\n\u003ctd\u003eAmbient\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTotal Power Consumption\u003c\/td\u003e\n\u003ctd\u003e4W (±5%)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Voltage\u003c\/td\u003e\n\u003ctd\u003eAC 220-240V 50\/60Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimmable\u003c\/td\u003e\n\u003ctd\u003eNo\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\u003eAverage Life\u003c\/td\u003e\n\u003ctd\u003e15000hrs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003e3yrs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUKCA\/CE\u003c\/td\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\u003ctd\u003ePieces Included\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInstallation\u003c\/td\u003e\n\u003ctd\u003ePlug-in Item\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Care\u003c\/td\u003e\n\u003ctd\u003e(1) Wipe clean with a dry cloth, do not use any cleaning detergents, do not use rough or coarse material to clean.
