On the face of it, the product operates in a similar capacity as the latest Nest Hub — and uses a similar technology. Radar sensing is at the heart of it, measuring changes in the user’s body to deliver a kind of passive health monitoring system — i.e. one that doesn’t require you to put on a smartwatch or fitness band.

Of course, there are a lot more variables with a lightbulb, versus a product specifically designed to sit next to your head while you sleep. There are also some broader questions here, like, is the sense of convenience in not wearing a fitness band — or even ring — so great that you’d want to outsource it to a lightbulb? And what of accuracy? It’s tough to compete with readings from sensors mounted directly next to the body.

The smarthome gadget has Bluetooth and Wi-Fi functionality, and could have some potentially useful applications for eldercare, including fall detection. The Verge has a bit more insight into the bulb, which is set to launch toward the end of the year for an undisclosed price. Sengled announced a number of other products at the show, as well, including a smart oil diffuser, a portable lamp and a motion sensor.
