This compact smart bulb in standard GU10 size fits most luminaires. It provides 16 million shades of coloured light with an illumination quality previously only possible with larger bulbs. A colour temperature range of 2,000 to 6,500 kelvins delivers a wide range of light from soft ambient lighting to bright daylight. Part of a smart lighting family, the bulb can be controlled either via the bridge hub or Bluetooth app.
