The UK banned incandescent lights in 2016 and Christmas hasn’t looked the same since. Has anyone found a replacement?

Those have 120Hz PWM, which is low enough that I'd notice it in my peripheral vision and it would trigger migraines. Since it gets that from half-wave rectification, on UK mains (which are 50Hz instead of 60Hz like in the US), that would drop down to 100Hz, which would be really bad. The flicker would most likely be noticeable to most people, even people not super-sensitive to it like I am. It's a pity they don't just run off DC, so you could just swap out the DC adaptor with a UK one, which would also avoid any potential safety issues with crappy voltage transformers. It's also a pity more people aren't more discerning about their LEDs. I won't buy anything below 95 CRI and ideally 97+. If everyone did this, we wouldn't have the problem of so many crappy LEDs because there would be more high CRI ones available. As it is, they are really hard to find, because most people don't even know there's a difference, so the market for them is pretty small. As the video notes, high CRI warm-white LEDs look good on their own (low CRI white ones look really harsh) and if you wanted to, you could just paint them yourself. I used to have some really nice high-CRI xmas lights, but they stopped working and the company doesn't make them anymore. Haven't been able to find a good replacement in the last couple of years.
