We’ve grown accustomed to tracking sleep with smartwatches and fitness trackers, but wearing something on your wrist to bed can be tedious. Companies like Google have come up with unique ways to track sleep using radar, and now smart lamp company Sengled is applying the same technology to its lamps.

Sengled’s new lights feature Frequency-Modulated Continuous Wave (FMCW) radar, which, when combined with Sengled’s AI, can measure your sleep quality during the night, along with your average heart rate and body temperature. It works similarly to Google’s Soli chip, which is baked into last year’s 7-inch sleep sensor Nest Hub smart display.

This kind of radar-based technology has gained popularity in recent years as it is less invasive in tracking vital signs for multiple people. If Sengled lights detect abnormal changes in your baseline of readings, the colors of the light change to signal a potential problem.

The data tracked by the smart bulbs will be synced to the Sengled Home app, though the company has plans to integrate with other third-party health apps. If you buy multiple lights, you can set them up to monitor general behavior, such as if someone has fallen in the house and needs emergency help.

Health features aside, Sengled’s latest bulbs are pretty classic smart bulbs, with both Bluetooth and Wi-Fi so you can set them up on your home network using a hub as a controller. The lamp itself has a Color Rendering Index (CRI) of 90-plus, which means it gets nice and bright. Sengled’s lights are also compatible with Alexa and Google voice commands and support Apple’s HomeKit as standard. Sengled did not mention Matter support for integrating its lights with other smart home products from other companies.

Sengled’s health monitoring lamps are still in development, but the company says the lamps are expected to hit the market in the fourth quarter of this year – that’s a long way off, so we’ll see.
