2019 Lighting Technology Trends: What is Bluetooth Mesh?

By David P Hakimi / February 20, 2019

Unlike wireless lighting systems like Wi-Fi, Bluetooth Mesh is designed for large collections of devices, numbering into the thousands. Switches, HVAC, sensors, light fixtures, and shades can communicate with each other by forwarding a message, or command, across all the devices in that Bluetooth chain until reaching the destination to perform said operation, (i.e. turn ON the 3rd floor office lights). The communication, instead of passing through your WiFi router, comes from the originating device and travels from light fixture to sensor, to AC unit, to any other chain of Bluetooth Mesh enabled devices, like a Bluetooth highway or a body’s central nervous system, until the command reaches the lights on the 3rd floor.

There’s a lot to think about when it comes to lighting a museum gallery. On the technical design side, there are two main factors to consider: light color temperature, or the warmth or coolness of a light source, and the Color Rendering Index (CRI), or the system used to indicate relative color rendering ability.
