Is non-islated mains LED lightbulb illegal?

below 25w doesn't have to be pfc....not at all (in Europe).
However, led lightbulbs with significant capacitance following the mains diode bridge are damaged if connected to a triac dimmer (due to resonance of the emi filter inductances and the electrolytic cap.)...therefore, even low power led lightbulbs (eg 7w) are made fully power factor corrected as then they don't have much capacitance after the diode bridge.........

so, due to these triac dimmers (which , incidentally are only actually meant for use with incandescent), virtually all led lightbulbs are made with pfc, apart from the really really cheap ones.

yes but see in the table 5 of this file, they said that there is power factor requirement if the power is below 25w (page 13)
 

In Table 4, Page 12 of the article ref'd in post #23, it says Power factor >0.5 if power <25W.
To be honest, virtually any SMPS will have power factor >0.5, as long as the electrolytic caps after the rectifier are not too massive
