Does anyone have a figure for the switch-on inrush current of a typical
9W LED bulb? Preferably for 230/240V.
Not sure wat the 'typical' circuit is, this is wha tI found in my LED bulbs from Cina:

peak current is limited by the 1uF series cap at 50 Hz here.
There are so many different LEDs around,...
Ah, I should have formed my question more carefully. I know about those early bulbs. They were the precursors to modern ones that use switching supplies. These later models are the ones I mean.
