Cree does it again-160 lumens per watt @350 mA

[Bright_Light]

I was talking to someone a few weeks ago and they said Gene was mucking around with them then. Was specifically talking about the dorp-ins for maglites, but you know there will more than just that.

Excellent! Maybe Gene can get Don Mcleish to design him another reflector for the XM-L. It sure is a great time to be a flashaholic.... 😀

from an total output/power aspect only it seems like this is only a modest improvement over say the SST90, which i think the spec sheet said 1K lumens at 3A.

This is of course disregarding any cost or packaging improvements since the SST is a big expensive LED.

The XM LED Demo was a good submission to this thread, the 750 lumens is quite impressive! I'm new to flashlights, but with the new XM-L lights going to be the biggest difference that we have seen?

How do these compare to XP-G's ?
Sorry, this stuff does not seem so basic for just anyone to understand.

 

[MichaelW]

The xp-g can be extremely overdriven to about 500 lumens.
The xm-l might reach 1500 lumens.

So we should see another single die [monolith] emitter capable 1,000 lumens OTF (in addition to SST-90, SST-50)

Not necessary a game changer, but a 'next generation' mc-e.
Not a competitor to xp-g because of the larger die size, and package size.

Just eagerly anticipated evolution.

Anyone know what the price is likely to be on this light? If it is a lot cheaper than the SST-50 it will be great news.

 

[Techjunkie]

Wild speculation... I'd guess $16-$18 each from the same places presently selling XP-G for ~$7 and MC-E for ~$14.

The more important question is, when is the Cree XM-L going to start showing up in production flashlights or drop-ins in quantity and who will be the first.

Been waiting 6 months now.

I am getting tired of all these under-driven Luminus SST-50 J-bin flashlights that put out less than MC-E M bin and hardly more than XP-G R5 from DX.

 

[Techjunkie]

Tell me about it... I've been stockpiling hosts and drivers and other parts ever since I heard about these. I've got 5 lights planned and all they're missing are these emitters.

 

[arrrx]

Cool! can't wait to have one piece on my flashlight.
But...how about the price...

I think a XM-L in neutral white in an EDC would be nice. It should offer a broad beam due to the large die size not being well focused in the standard reflector sizes. However, like how many are disappointed with the XP-G due to lack of throw, those same will probably be disappointed with the XM-L. The reflector would need to be both large diameter and deep to really focus it well, but if it is, it should throw very well. Only consequence would be the size increase in the light. For EDC, that's not really an option, so a broad wall of light it is, and should work well for EDC. Not sure how well the XM-L will work in other applications where larger lights typically (or used to) offer more throw. Hopefully the current standard prices for lights in each class don't go up a lot with the introduction of the XM-L.

 

[moviles]

how many time we must still wait for buy this leds in cutter or other dealers ?

 

[Techjunkie]

Would someone kindly post here in this thread when these are finally available as bare emitters or on stars from DigiKey or any other US dealer? (Or KD/DX if they beat them to the punch.) With my new job and crazy schedule, I don't get to frequent this forum as much as I used to and I don't want to miss the launch. Thanks! 🙂

We are getting close looks like pricing will be close to double and xg-g.

cree XM-L bin T6 ... only 910lm/3A ... I am not satisfied ...

:thumbsdow :thumbsdow :thumbsdow

 

[tstartrekdude]

Where did you get that number from? and is that's all they are going to give us than yeah no kidding that's not satisfying :scowl: That workd out to the same serfice brightness as the old R2 xr-e's with the EZ1000 chip. i was hoping at lest that it would use the same quality die material as the EZ900 R2's(about 1100 lumens at 3 amps)...the new N bin mc-e's are the same efficiency as this as well, but this package is still better than the mc-e though so i guess i am still making my new light with a warm one once they come out.....I WANT MORE SERFICE BRIGHTNESS CREE, OBEY ME NOW AND DO MORE SCIENCE!!!:whoopin:

EDIT: *plays with mag 1185 and calms down*

 

[pepko]

... from cutter's preliminary datasheet ...

:thumbsdow :thumbsdow :thumbsdow

My notes from 4-12-10 are that at 2 A, the XM-L LED produces 750 lumens at 110 lumens per watt. If all things are equal, I would anticipate that at 3 Amps it would be closer to 1125 lumens.

 

[HumanLumen]

The relationship with current is not linear.
Looking at the XRE curve and dividing the current of that curve by 4 (as that is the equiv current desity for 4mm2 cf 1mm2 for EZ1000), I would expect 1.75(for 750mA) div by 1.35 (for 500mA) x 750Lm (4 x 500mA) = 972 lumens, so I think we will be given a little more than 910Lm at 3.0amps offered here - its another R5 bin supprise.

I'll be satisfied with 900 lumens. I like the fact that it could possibly replace my dual linger special and have a lower low since it will only be one led, plus the beam will look much better. I hope they make optics for it.
