I have basic knowledge of electronics but not enough for doing this project so I need some help here. I want to make LED lamp. It is pendant lamp that is pluged to wall outlet (220V AC ). I plan to use a cluster of 20 ultra bright 1W-3W (3.6V) leds. So, i need to convert this to DC i guess and what do you recommned, serial or parallel connection and which transofmer to use for that.
TIA
