Philips has an impressive portfolio of smart, connected lighting solutions to kit your house out with. In fact, it's arguably the most complete lighting system available.

The bulbs come with either a bayonet B22 fitting or E27 screw fitting. It's a great place to start if you don't have any smart lighting yet. 

Being Hue there are, of course, other bulb types to choose from. They offer spotlights, separate mood lamps, even designer lamps with built-in Hue support and LED light-strips. You even get the option of connected dimmer switches and motion sensors. All of which can be controlled by Alexa.

View offer on Amazon UK | Amazon US


For all those non-smart products you have lying around, there's a simply solution: a Wi-Fi Plug. Simply plug your regular lamp, kettle, coffee machine or whatever in to one of these, and have it switch on as soon as you give the command to Alexa. As long as it's a simple on/off device, you'll just need to tell your Echo to switch on that specific plug.
