1. A method of upgrading an illumination device disposed at least partially within a recessed-can lighting fixture, the fixture being associated with an outlet electrically connected to a source of power, the method comprising:
- connecting to the outlet a discrete driver module comprising (i) circuitry for supplying power to and controlling at least one light-emitting diode and (ii) a connector compatible with the outlet; and
after connecting the driver module to the outlet, mounting within the recessed-can fixture a discrete lighting module configured to operatively couple the driver module to at least one light-emitting diode; and
electrically connecting the lighting module to the driver module such that the lighting module is electrically connected to and otherwise physically separate from the driver module.

22. An illumination device comprising:
-
a discrete driver module comprising (i) circuitry for supplying power to and controlling at least one light-emitting diode, and (ii) a connector for connecting to a source of power; a discrete lighting module configured for electrical connection to but otherwise physically separate from the driver module, the lighting module comprising (i) a mechanism for mounting the lighting module within a recessed-can lighting fixture; and
(ii) an electrical cable electrically connecting the driver module and the lighting module, the lighting module configured to operatively couple the driver module to at least one light emitting diode;wherein (i) the driver module and the lighting module are collectively sized to fit within the recessed-can lighting fixture and (ii) the electrical cable is the only physical connection between the driver module and the lighting module.
