New version 2015: 1020 lm instead of 960 lm

For lamp itself others have written here at some length, it's just amazing what you can get out of such a small lamp to light now.
Goods arrived when promised.
BUT:
It was not the offered version, but already the new 2015 version with a brighter LED: The lamp should now deliver 1020 lm instead of 960 lm according to data sheet. Really perceive will be the 6% but probably not.
