Teardown of a filament LED lightbulb from Ebay for $1.50 including shipping. Rated 220V 50Hz, the nominal power is 2W, real power is cca 1.6W, it has a E14 screw base. It is quite bright and looks nice, but there's no fuse in it. There's also no filter capacitor, so it has a lot of 100Hz flicker (not visible to the human eye unless you move it fast). It has a capacitor dropper in it with a 330nF capacitor, 1M discharge resistor and 1k inrush resistor. The 330nF multi layer ceramic capacitor looks quite small for the mains voltage.<br /><br />You can support me on Patreon:<br /><a href="https://www.patreon.com/DiodeGoneWild" target="_blank" rel="nofollow">https://www.patreon.com/DiodeGoneWild</a><br />...<br /><a href="https://www.youtube.com/watch?v=f5IekLLWbyU" target="_blank" rel="nofollow">https://www.youtube.com/watch?v=f5IekLLWbyU</a>
