New CREE!

New CREE!

Nice!

Not sure if its chip is smaller than XRE or XPE, should be good for a thrower anyway.

I wonder when we will start seeing it in flashlights and how many lumens its capable of.

Also I bet even though it says they are cheaper to produce the prices will be higher because they are new.

*edit* Just found a article on it here

According to CREE datasheet, it pruduces about 287 lumens at 1A(max).

So I guess its for budget lights and not a competitor to high output LED's then?

According to the data sheets this new XB-D is MUCH smaller than the XRE and about half the area of the XPE.We'll have to see about the max output, but this is pretty exciting.

I only see the package size of 2.45x2.45mm, which seems to be for the chip.

287 lumens at cree's max current of 1 amp?

If the die is around the EZ900 size or (fingers crossed.....smaller) this would have a really high surface intensity and be an awesome emitter for throwers.

I am so excited to hear more about this. Tiny and efficient. You could make a triple out of it in a light that is still pretty compact and have awesome runtime and wicked throw.

Looks like it has the brightness of an XP-G in a package the size of an XR-E.

So as someone else above mentioned, it should be quite a thrower, and have longer runtimes to boot.

Great news for thrower fans like me! I’ll be all over this.

that article makes it sound like a lower price is a big part of the motivation, so lets hope the 'new costs more' doesn't happen.

then it won't be thrower only - If they're $5 each on 10mm star I'll cram about a dozen in the cheapest suitable host I can find

Looks good, pros and cons.

115 deg. So could be doable in current XM-L class reflectored throwers and give you crazy throw. But for aspherics it might not be optimisable.

It is like a supercharged XR-E with near XM-L efficiency. BTW, where is the mentioned die size? Can't see that it's smaller than XP-E even. There is mentioned package size though.

Die size is not mentioned but if the whole chip (see pictures from bottom of the sheet) is 2,45x2,45, is it possible to guess the die size from the relative dome size?

Here we go again. It seems to happen every 9-12 months and every time my wallet takes a hit. :)

One aspect we shouldn't forget though is that flashlight enthusiasts make up a tiny percentage of all sales. We may be part of what pushes development, in some ways like racing pushes improvements in engine and ECU developments, but the money is in the mass market.

I talked to some vendors at last year's CeBit trade show in Germany and at least the people I spoke with told me they were focusing on anything but flashlights: automotive (lots and lots of exciting stuff happening behind closed doors, both in terms of lobbying and R&D), industrial, commercial and municipal applications. That's where they think the money is going to come from in the future so that's where the money goes right now. And that is what drives "brighter, more efficient (immensely important), smaller, cheaper" development cycles.

Of course, we are all going to profit from that. In some ways sooner (economies of scale, etc) and in some later (trickle down).

Looks exciting. I am am big thrower/XR-E fan so this could be good!

Agreed, Cree is not focused AT ALL on flashlights. If you listen to the hour long interview with one of the cree co-founders that I posted, the word flashlights is not mentioned once. They make billions of LEDs per year so the percentage of those that goes into flashlights is very, very small.

It's not too bad, the XM-L still lives on for high-output + efficiency. This is not going to be too bright, and the XM-L is anything but expensive. But this bugger will throw and it will be great in a 5 x XB-D! (slightly more than 1000L OTF and throw great as well)

let's hope they'll soon make a sipik style light with this led!

Abandon your high hopes about this led... At least if you count on its "throwing" abilities.

The "die" size is the same as chip size. As you see, the phosphor covers whole chip area so surface brightness will be very low (compared to XP-E/XR-E/XP-G, etc.). What's more, because the dome doesn't cover whole die surface it will be also bad when used in reflector.

Our local dealer has them in stock for ~1.7$/pc (bare LED without MCPCB). They're purposed for industrial applications, not flashlight market.

None of the LEDs in flashlights are purposed for flashlights.

If that's the case then it'd be good for the mass market, like commercial/residential lighting and aquarium reefers doing LEDs. The latter lighting systems can cost several K for a big tank. Right now those LED spots are dominated by Asian LEDs, i am using quite a few of them. Epistar. I have some 3W E14s which are Bridgelux though. They are still expensive!
