I got a 220v LED bolb... See pictures.... The wierd thing. How can it work on 220v? I see a diode brigde, 3 LED's, a 0,33uF 220v capacitor, a inductor, some small diode, capacitor and resistor....
Im working with low voltage normally, but when you have to go from 50 to 18v you need a voltage devider. And when you go from 220v to someone low you need a powersupply. I dont get this... how can it work?
