First stepping down voltage from 220V with a transformer. Then converting from AC to DC with a full bridge ractifier and a capacitor. Capacitor smooths the output voltage at 20V.

Increase the lamp to 1W (50mA) and beyond.

Any good tips on how to make it more stable at higher power ratings? I guess we cant just increase capacitance... :)
