It's built to recreate the look of a traditional halogen GU10 spotlight, with a full glass lens and a backlight effect similar to a halogen dichroic lamp, while running on a fraction of the power.\u003c\/p\u003e\u003ch2\u003eKey features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eDimmable — compatible with LED-rated dimmer switches\u003c\/li\u003e\n\u003cli\u003e850 lumen output, cool white light\u003c\/li\u003e\n\u003cli\u003eFull glass design so there's no clash of colour or finish between bulb and fitting\u003c\/li\u003e\n\u003cli\u003eRated for 25,000 hours of life\u003c\/li\u003e\n\u003cli\u003eHigh colour rendering, CRI80, for natural-looking colours\u003c\/li\u003e\n\u003cli\u003eRated for over 100,000 switching cycles\u003c\/li\u003e\n\u003cli\u003eCOOLFIT technology to guard against overheating\u003c\/li\u003e\n\u003cli\u003eStandard GU10 twist-and-lock base, 5 year warranty\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhat this bulb is best for\u003c\/h2\u003e\u003cp\u003eThe cool white colour and high 850 lumen output make this a strong choice for kitchens, bathrooms, home offices and any room where a brighter, whiter working light is preferred over a warm amber tone.
