    Abstract: Techniques for employing an enhanced light device to determine desirable information to a user are presented. Such light device(s) can comprise or be associated with a light management component (LMC) that can employ sensors to monitor respective characteristics or conditions of a device, an environment, and/or a user to determine respective contexts for the device, environment, or user, wherein the user can interact with or be in proximity to the device or environment. The light device(s) collects data, including sensor data, relating to the device or environment from the device, the environment, or other data sources. The LMC determines a desirable subset of information to present to the user based on the respective contexts. The LMC facilitates presenting the desirable subset of information to the user via the light device or a communication device of the user that is communicatively connected to the light device.
