Mains LED waveform

I saw a quite interesting looking waveform from a 10W LED floodlight powered from 230V AC.


It looks like when AC voltage waveform instantaneous voltage lower than some voltage, it takes practucally no current and above it it looks like a constant current load.

This is picture of the light.


This looks like this uses one of those direct mains AC powered LED modules, like those described in detail here:
