I'd seen these lamps online from various suppliers, but my first attempt to buy some failed when the high profile Chinese sellers website automatically "corrected" my delivery address to America and also changed the linked contact phone number to the American country code too!!! (Not surprisingly the package went missing and they refunded the order.)
So here's one from ebay, and it contains seven 5050 LEDs giving 21 LED chips (three per package) and a neat and functional capacitive dropper using a 330nF SMD capacitor with its 1M discharge resistor tacked right across its top. there's also a beefy 680 ohm series resistor to limit inrush current and a bridge rectifier on the other side of the PCB.
Simple, but actually very robust and functional.
I really like this little lamp. It's a very solid and sensible construction.
