Yes, we knew that already. We just discussed something off topic about our preferred emitter design based on the nice 144A which doesn’t have thermal pad
“…Nichia claims its 319A high-power LED is a record breaker by achieving a whopping 164 lm/W at 700 mA (5,000 K). And the 319A is a production device, Nichia say, i.e. not one shining brightly deep down in a liquid nitrogen vessel or in the minds of a few theorists at MIT. Mass production of this super LED is planned for late this month or early January 2017 so with a bit of luck you will be dazzled by your daughter’s new flashlight for Summer Camp.
The size of the 319A is 3.5 x 3.5mm and the device and is foot-print compatible with earlier 3.5-mm LEDs, if not optically. Breakdown is specified at 1,050 mA (~3 W).
A variant with 3000 K color temperature is expected to yield 415 lm with a minimum CRI (color rendering index) of 80. This device won’t give you much deep red though as its R9 CRI specification is zero.
Nichia showcased a number of breakthrough LED technologies at the recent Lux Live show in London’s Excel Centre … what’s in a name….”
The Nichia 144A I got, rated 900 lumen in about the same 8,4 watt power output with CRI 9050

And 1000 lumen in hard to get higher rank
Very narrow TIR with frosted center aspheric lens, Gaggione LLC49R. Its not spiegelei (well, very subtle) in reality, it’s a very cool looking hex projection.
With normal plain TIR optics, you can see the hex projection.
