As for the 110V, if you're lazy you can simply half the number of primary turns and adjust the frequency if necessary (and mind the core and FET temperatures!). Although I would strongly suggest using a transformer calculator to find the correct values.
Is using PFC mandated by EU law for every one-off DIY project that uses over 70 Watts?!!

Thank you. I hope not. That would be outrageous and disappointing.

@gootee

No, that is a restriction for marketing them. You can build whatever you want I only mentioned it as a comparison as the other member was not sure whether to put a PFC to it or not. But yeah I forgot to mention my comparison does not touch upon DIY stuff.
