Abstract Illumination devices (10), systems and methods that convert an alternating current (AC) supply (14) to a direct current (DC) for powering a plurality of light emitting diodes (LEDs) are disclosed. An illumination device (10) comprises a full wave rectifier (12) for converting the AC supply into a direct current (DC). A current limiting diode (CLD) module (16), comprising at least two CLDs coupled in parallel, is coupled in series to an output of the full wave rectifier and a light emitting diode (LED) module (18) comprising a plurality of LEDs is coupled in series between an output of the CLD module (16) and the full wave rectifier (12).
