Schematic diagram of a 220V 50Hz/60Hz 5.5W LED Light Bulb made by FSL:
The light bulb produces 460 lumens, has a color temperature of 3000K and is guaranteed for 25,000 hours.
It's a cheap bulb, and no surprises, the small PCB contains only a simple capacitor dropper, a rectifier bridge, a smoothing capacitor, two current limiting resistors and two small SMD discharge resistors. There are 10 LEDs mounted on an aluminum-substrate PCB, all connected in series. Each LED package contains 5 discrete LEDs and shows a voltage drop of around 15V.
