16 million colours
The LIFX Plus range offer some of the brightest Wi-Fi enabled LED light bulbs, with 16 million colours to choose from including warm to cool whites. You have a full intuitive control over the bulb, allowing you to control lights individually or as groups if you own more than one LIFX smart bulb. What’s more, you get all this and no hub is required. You can set timers, pick from beautiful light themes or create your own custom scenes with flexible brightness and colour options. Experience how subtle adjustments in tone and brightness can enhance the comfort of any room by playing around with your lights.

Ideal for wall mounted or stand alone lamps
The LIFX Plus smart bulb uses a large Bayonet cap fitting (B22 BC) to connect into fittings of the same type. These fittings are generally found on wall mounted or standalone lamps. LIFX Plus has an output of 1,100 lumens and the wattage output of this bulb is 11W, which equates to a 75W output when compared to a standard filament bulb.

Easy to setup - no hub required
Setting up the LIFX Plus smart bulb couldn’t be easier. Replace your existing B22 lightbulb with the LIFX Plus like any traditional light bulb. Simply download the app, connect to your Wi-Fi network and you’re ready to go. No hub is required for this process. The built-in Wi-Fi and LIFX cloud offers full lighting control via Wi-Fi with the LIFX iOS, Android and Windows 10 apps. This means you can access your bulbs anywhere, anytime via the cloud.

Rated 5 out of 5 by from Does exactly as expected with ease! I'm slowly kitting out my grandparents' house with smart home features, and this was the next stage in that (after getting an Amazon Echo & Nest thermostat). Set up was lightning speed quick and we will definitely be purchasing more. I'm mainly leaving this review in relation to a previous review which says it keeps disconnecting from the wifi (which it needs to work). I would imagine this is due to a poor quality router than the bulb itself. In any case, my 90-year-old grandparents both can use it easily and look forward to the next installation of a smart home device!

Rated 1 out of 5 by from Does not work reliably These bulbs disconnect from wi-fi at least once a day, sometimes several times a day. I have tried everything I can to make these bulbs work. My other wi-fi connected devices work reliably, these bulbs do not.

Can I operate these bulbs using a normal lightswitch? (I mean without ill effects, I know I can switch it off, but will it work normally when I switch it back on?)

Asked by: Graham H
Found the answer myself. Yes, they work as a normal bulb. When switched on they show the colour and brightness that was set when they were last turned off.
