If you live in some chosen european countries and you have a non food discounter called “Action” at hand - they have E27 17W 2500Lm Bulbs for just 2,99€:
That makes a theroetical 147Lm/W - very rare to find as you all know.
I have bought multiple ones and they are indeed very bright and the light doesn’t seem to be of low CRI as well.
With 17W and that price, I think they won’t last forever, but which one of those lights does.
Action also has some 4000K and 6500K bulbs - both not as efficient and powerful, but especially 4000K bulbs are quite rare
