Okey, 100 lm/W is probably correct value, but where i find similary LED chips but 200lm/W efficiency like my second link, where is 210lm/W E27 pulb?
Not available to us mere mortals.
Certain countries are allowed these bulbs. This is some kind of super-weird New World Order thing, given that everything else is regulated for best possible efficiency. While it is perfectly possible to make a 200 lm/W LED bulb, and reasonably inexpensive to do 150 lm/W bulbs, the actual market in our "free Western market" is from 50 - 110 lm/W, absolutely nothing above 110lm/W, no matter how much you want to pay. This applies to both fixtures and bulbs. It feels like after the "pandemic" it has got even worse, all I need are some kitchen light fixtures but I have now set a principle I will not buy anything below 90 lm/W yet it is now difficult to get fixtures even 100lm/W in Finland!
You need to import them yourself from some freaking Saudi Arabia or whatever, I already forgot where you can get those forbidden LED lights, because they are actually manufactured, just not for us.
Or just design and build your own lights.
Regarding your question, note the Ebay LEDs are total crap. If you are lucky, they work at all. Maybe 50 lm/W, maybe 100, who knows.
