“Internet of Things” light bulbs aren’t a new thing. Bulbs you can control from a phone app, like the Philips Hue and the GE Link Bulbs, have been kicking around for years.
The concept: You can turn these lights on and off, set them to a schedule, or even change their color, all from an app. The drawback: They’re expensive, because they don’t work without a separate hub, a router-looking thing that requires an internet connection and power.
Now, though, there’s the TP-Link bulb. It doesn’t require a hub. It’s a self-contained smart bulb you just screw into any light socket or lamp. You use its app to introduce it to your WiFi network, and boom: Self-contained LED bulb that you can control remotely.
