New quad die Cree MK-R up to 200 lumens per watt

sure wish those weren’t 12V

Why not? If they’d be ~3V, they’d be hard to regulate from 1 cell… with 12V, and a boost driver, you can drain 1 cell fully, staying in full regulation all the time.

So is it 4 XP-G2 or XM-L2 or something else?

got a link to a 4.2v in (or 8.4v in), 12V out, 15+W driver?

Nice, seems they are attacking bridgelux territory. Efficiency numbers are quite good but CRI90 still takes large performance hit and they are hiding R9 numbers as snake it’s legs…

Perhaps a driver meant for multi-XR-E applications. They usually run in series and only use between 1 and 1.5A. Should meet your voltage and amperage requirements.

MC-E >>> XM-L
MK-R >>> ???

I will wait for next gen single die CREE ??? :wink:

that’s actually a great idea - i have 5 of the last version of these I haven’t done anything with

could probably still find mce drivers somewhere

MT-G2 maybe? :D

I just saw this announcement on my facebook page, at this speed rate -> pls.
wake me up when we hit 300 lumens per watt mark :smiley:

Nope, 6-8mm single die area at about 2000 lumen/20W :wink:

Lithium-ion cells are likely not even on the radar for the designers of this LED.

I’m almost positive TaskLED’s Hyperboost can handle 17W input over the voltage range of 1 li-ion cell if it is properly heatsinked.

Ahh… seems Cree was good on their statement about releasing a 200lm/W LED before 2013 after all.

I read an article earlier this year about Cree LEDs…. and the representative stated they would have a 200lm/W LED released before 2013. For a moment I though perhaps they were referring to the XML-2 but it had fallen short.

So the numbers for this at 25°C would be ~2000lm at 15W? Looks like the SST-90 has competition :smiley:

Or ANY of our LEDs.

This is what I look forward to


Also this LED may do well for automotive applications

I noticed the thermal resistance is lower, we all know how much that helps

Shadowww is waiting for Match’s over-drive test with direct copper mount

I definitely am happy to see this, pretty awesome seeing a 200 lumen/watt component hit the streets. This coupled with the XM-L2 give a pretty good 1-2 high end punch.

How about this: http://www.cree.com/led-components-and-modules/products/xlamp/arrays-nondirectional/xlamp-cxa1512

Or why not go all the way with this: http://www.cree.com/led-components-and-modules/products/xlamp/arrays-nondirectional/xlamp-cxa2530 :slight_smile:

LOL nope again, Just 6-8mm^2 of die area .

For making Flashlights we need more lumen/die area :wink:
