Tweak, toggle and tinker with the tone of your rooms with this adjustable smart bulb. Just install this LIFX bulb like a regular bulb, synch your smart device to it through Wi-Fi (no separate Hub required), and enjoy fitting-free dimming and huge adjustability. Set them to come on automatically or on schedule. LIFX's app (available on iOS, Android and Windows 10) is the control hub of your smart bulb, so you can transform your room's lighting from the sofa. Simple control by app Installed like a traditional bulb, just pop it in your light fitting, and download the LIFX app to start controlling. Set schedules, so your bedroom light could fade in slowly when your alarm goes off, or your lights come on when you arrive home. You can also create your own lighting scenes for the ultimate personal touch. And with LIFX, because the Wi-Fi is built-in, there's no need for an additional hub unit. Day & Dusk Inspired by the sun, choose from over 1000 shades of cool to warm whites. So you can wake up with a gentle sunrise, enjoy midday brightness, and relax with dusky tones in the evening. Energy efficient power With 800 lumens, this bulb is energy efficient. Based on a 3 hrs/day usage, this is estimated to last over 22 years. Such efficiency and long life-span can contribute to the greener home too. Works with smart assistants Control your smart lighting with just your voice. Lifx bulbs work with Google Assistant, Alexa, Cortana and Siri smart devices, as well as HomeKit and SmartThings.
