LIFX

LIFX is a brand of LED light bulb that is controllable using a smartphone app, including the ability to change the color of the light. Each bulb is a separately-addressable networked device (though only the "master bulb" actually has an IP address; however there are future plans to give all bulbs an IPV6 address when this protocol is fully supported). LIFX was launched via a Kickstarter campaign, and its first batch sold out in advance; future batches are planned.
