Smart bulbs were among the first products to have commercial success in the connected home. While simple in theory, they have the very practical application of allowing users to control electric lights from smartphones or tablets.
Interactivity is one of their key features. The lights allow users to interact with them in a number of new ways and offer other features that standard bulbs do not. Take color, for instance. Users can cycle through colors to change the mood of a room or make it more relaxing.
Of course the bulbs are also energy efficient because they are light-emitting diode (or LEDs). LEDs, as the US Dept. of Energy explains, are a type of solid-state lighting that use a semiconductor to convert electricity into light. They can also emit light in a specific direction, reducing the need for reflectors and diffusers that can trap light.
While many of these bulbs were meet with skepticism at first, they have endured and grown to be a staple product in many connected homes and, increasingly, work environments.
