Chinese LED mushroom / toadstool light.

Another variant on these popular nightlights. This version is actually not too bad, but has non pluggable LEDs which is a shame. (Most others have little two pin LED sockets at the ends of the stems.)
Pretty typical capacitive dropper circuitry, with the only slight niggles being the low voltage rating of the electrolytic and the swapped polarity colours going to the LEDs.
This version has no light sensor, but has a manual switch on the front.
