Ring is branching out from its usual doorbells and security cameras to produce truly connected lighting, although it's probably not going to replace your corner table lamps any time soon. An FCC filing has revealed that the Amazon-owned firm is prepping a Bluetooth-capable light bulb. It appears to be a floodlight that would complement Ring's existing security systems, but it's still a significant step for a company whose dedicated lighting has so far been limited to self-contained systems rather than screw-in bulbs.
