Interesting news. Would be good to see document as well.
No flip chip is also welcome (I hate ‘Cree rainbow’).
Also, sometimes in the future, Cree should also make a domeless 5050 LED as well, there could be long lines forming for that.
Some bottom lines:
Cree should really improve its CRI classes, instead of ‘min 0 typ 68’, ‘min 70’, ‘min 80’, ‘min 90’, they should use ‘min 80’, ‘min 90’ and ‘min 95’ - under CRI 80 it is only garbage.
Waste no time :)) my friend, send 'em a suggestion so we can all enjoy the improvements ASAP.
It would also help more than a lot if people were to stop buying :-D “garbage” low-CRI led emitters, like me and others do. And while we're not the only customers, this is no license to get off our donkeys. O:)
Similar Vf, similar output it seems. Tests will tell which is better. Cree is likely to offer CRI 68-70-80-90 while Luminus has 70 and prepares 95.
Cree is likely to offer many CCTs while Luminus is cool only and CRI 95 will be warm only, at least initially.
Any hints on die size?
I wonder how’s beam greenness…
The picture looks all yellow, but you can see the sides of the die, so there’s apparently no phosphor covering the whole thing.
Just seems the picture is all yellow (even the dome).
…or did they just adapt a picture of an XM-L2 ?
I hope they will use beefed up bond wires.
You can see in the tests that LEDs with bond wires increase in Vf when you push them hard.
Hopefully there will be an XP-G sized “new old style” one in the planning too !
If you go to the Cutter website and check their blog post area there is a link for Cree PCT version four. It’s an xlxs file that has some early xml3 data in it. Power wise the xml2 has mostly the same performance except the xml3 is rated for five amps.
