Abstract: A modular illumination device, and associated systems and methods, are provided. In some cases, a hub is provided. The hub can, optionally, be configured to receive at least one module via an interface. The hub can comprise an optional fitting configured to be mounted in a light socket, an optional networking component, and/or an optional illumination source. In some cases, the hub can be coupled to a module such that an external surface of the module occupies a relatively large percentage of the external surface area of the coupled hub and module and/or such that a substantially smooth surface is formed between the hub and module. In some cases, the hub can be coupled to a module having a relatively large volume. Also disclosed are covers configured to at least partially enclose wall-mounted electric switches, systems for retrofitting electric switches, and methods of retrofitting electric switches.
