In some implementations, a device includes a first full bridge rectifier configured to receive power from an alternating current (AC) power source, the first full bridge rectifier having direct current (DC) output nodes, a second full bridge rectifier configured to receive power from the AC power source, the second full bridge rectifier having DC output nodes, wherein the second full bridge rectifier is coupled to receive AC power in series with the first full bridge rectifier, a first set of light emitting diodes coupled to the DC output nodes of the first full bridge rectifier, and a second set of light emitting diodes coupled to the DC output nodes of the second full bridge rectifier.
