New Cree led - XB-H

Just reading that Cree has a new XLamp XB-H led.

Wonder how soon this will be used in flashlights

Damn you beat me to it. Ya i just saw this as well. Specs look quite impressive on this little guy too!!! Now only if http://pct.cree.com/dt/index.html would update to accommodate this as well

says 'successor status to the XP-G2'
the Typical Spatial Distribution is more a relaxed curve than the xp-g2 = slightly less throw

Could be real good in a headlamp w/ reflector

www.cree.com/ocf < this is their latest marketing, touting lumens per area as a measurement that they term OCF, or optical control factor. However, the area isn't the area of the die, it is the area of the entire package.

I'd be curious to see the whitewall beam quality compared to round domed LEDs. Hopefully in real world, the tradeoffs would be negligible. You can see the flats that allow for more side distribution, and since the light angle is fairly close to normal from any point on the emitting area, I wouldn't guess there'd be too much more losses than with a full dome.

Still, it would be interesting to see how they play with our optics designed for XP domed LEDs

From how I read it the die itself isn't any smaller, it's essentially an XP-G2 cropped as close to the die as they could? So same die in a smaller package?
Unless I missed something in the literature somewhere?

It could be one of the funky thick dies, hard to tell from that one pic. Anybody dig up more info?

Data Sheet:

The package is 2.45 mm and the die is not much smaller. XPG is 1.39 mm in a 3.45 mm package, while XML is 2 mm in a 5 mm package. I'd say this is more like a less efficient XML in a tiny package. I'm wondering what the benefit is except hype?
