The self-calibrating WLED module in accordance with the present invention providing precisely matched current outputs by matching each output current to a reference current, wherein matching a current output to a current reference is done sequentially for a number of current outputs, restarting at a first current output after the last has been matched to the reference current. The module may be implemented with components that comprise multiple WLED strings, a controller, a transconductance amplifier, an input voltage, a generator, a reference module and multiple current regulators. The current regulators provide required current respectively to WLED strings by varying the current through the WLED strings.
