The Philips Hue GU10 spotlight bulb creates perfect white and color light in a standard GU10 size that fits most luminaires. Now, any fixture can provide 16 million shades of colored light in a quality previously only possible with larger, non-standard bulbs. A color temperature range of 2000 to 6500 K allows a choice of light all the way from soft white to daylight. The smooth matte finish eliminates any light artefacts caused by reflections, for perfectly controlled light effects. Part of the Hue smart lighting family, the bulb can be controlled using either the Hue bridge hub or the Hue Bluetooth app.
