Tweak, toggle and tinker with the tone of your rooms with this revolutionary Smart bulb. Just install this LIFX A19 like any other bulb, synch your smart device to it through Wi-Fi (no separate Hub required), then enjoy fitting-free dimming and over 16 million colours, and 1000 shades of cool to warm whites. Fill your room with soothing blues at night, soft whites during the day, or any combination that you can dream of, and set them to come on automatically or on schedule. LIFX's app (iOS, Android & Windows 10) is the control hub of your Smart bulb, and you'll have a blast transforming your room's aura from the sofa. Smart Wireless Control With this high-tech design, you'll never need to deal with light filters or electricians again. Installed like a traditional bulb, just pop it in your E27 Bayonet fitting, download the LIFX app and get tinkering. Start with the basics like turning it on and off, then dimming from cool to warm whites. Next, you can play with the 16 million colours on the Colour Wheel, toggling brightness and intensity. Once you've found the perfect hue, you can then set schedules, so your bedroom light could fade in slowly when your alarm goes off for example, or your lights come on when you arrive home. On top of that, you can create your own lighting themes and scenes for the ultimate personal touch. And with LIFX, because the Wi-Fi is built-in there's no need for a cumbersome additional hub unit. Energy Efficient Power This economical LED design has a staggering 1100 lumens (75W equivalent), so you can save energy and boost brightness. Based on a 3 hrs/day usage, this is estimated to last over 22 years. This bill-busting efficiency and outrageous life-span will make your Smart Home a green one too. Complete Your Smart Home Set Up This LIFX A19 bulb can be hooked up with a host of other Smart devices. Control your lights by voice in conjunction with Amazon's Alexa. It works with the Amazon Echo, as well as Logitech Pop, Nest Protect and Nest Thermostat, Samsung SmartThings and IFTTT.
