Advance in LED tech?

Just found the above in my inbox. These really do appear to have double the lumen output per Watt of any LED lamp I've seen so far; about the same as the so called 'Dubai LED', but those are based on filament type LEDs.
Is this some step change in the advance of LED tech?

Those are the first A or B rated lights I have seen under the "new table" of figures. They seem to achieve 53% efficiency for the 2700K warm white lamps (just under 61% for 4000K), based on the theoretical 100% values of 350lm/W given here:

They also give typical LED values of 25-40% efficiency so it looks like those new lamps are a decent improvement, even if not beyond realistic expectations.

Might buy one just to try it, though usually I try to get the '100W' equivalent lamps (1500lm or so) when possible.
