60 lm @ 350mA and 100lm/w Cree LEDs presented

Re: 60 lm/w and 100lm/w Cree presented

No, actually you can call ETG on Monday and buy them, quit being so dense. I purchased mine in late December.

I'm not the only cpf'er that has them in hand...


Meanwhile, personally, I'd most definitely hold off on purchasing *any* Luxeon devices, since their better parts are "supposed" to arrive shortly. We'd have to assume there will be a considerable price drop in the current parts, once the better parts are released. Look at LumiLED's press release, the date of arrival is in there...

so thease are more eficant then lumileds?i love compition the more the better.

Most definitely raggie33, seeing is definitely believing!

Can you buy just one?

Re: 60 lm/w and 100lm/w Cree presented

Yeah, anyone selling the XLamp LEDs in small qty. without forcing a purchase of a whole engineer's kit? I'd like to see how well they work in conjunction with a "classic" Zetex ZSC300-based regulator.

Perhaps one of us should drop Photonfanatic a pm on how to get these little wonders?
Once he has them, things should get really interesting here.

Re: 60 lm/w and 100lm/w Cree presented

would be cool if they could get 300 lumens per 3 watts.hect even 5 watts that would be wicked bright.i foprget watage of a lumleds 3 watt but i think it was like 85

Re: 60 lm/w and 100lm/w Cree presented

maybe one of you guys who has them can post some pics comparing the cree leds with the luxeon leds

Re: 60 lm/w and 100lm/w Cree presented

Here is a photo of the old CREE part, from last year, before it was improved.

As far as the LumiLEDs Luxeons, if you read the press release carefully, they aren't even scheduled to hit the shelves until June. Still, if I was considering an LED flashlight that uses Luxeons, or purchasing a Luxeon, I'd definitely hold off purchasing anything, until the vendors get the new parts worked into their designs.

"Scheduled for summer release in white and seven colours, these additions to the Luxeon product line will set new industry standards in virtually every measured parameter. "

Re: 60 lm/w and 100lm/w Cree presented

ok i had seen that pic but how much brighter is the new improved emitter ? it should be at least 3-4 times as bright right ?

Re: 60 lm/w and 100lm/w Cree presented

I often wonder how vendors will differentiate between improved bins of similar parts, if more efficient LEDs end up with the same part number you will have to be convinced you didn't get the older bin instead when you purchase lights with them in them. There could be two of the same light with same stock numbers but one with improved LED selling for the same price.

I checked around and nobody else but cree seems to sell the 7090 but there are articles about it everywhere some of which claim it to be up to 50 lm/watt instead of 60. My guess is it may take a few years before you can buy these from a distributor instead of trying to get 1000 pcs of them from cree. I may have missed it but I haven't seen a CPF'er review one of these yet so if they have any there is either a gag order or they are holding out on us. From the little I have gathered cree is falling behind on production quotas to the big players wanting their product which probably means prices don't go down nor do the smaller distributors get any supply to sell in smaller quantities to enthusiasts.

I am still a cynical skeptic, and no I don't work for cree either, lol

Heres a little review. I bought a handful of samples from cree's
distributor ETG. And yes, they are QUITE impressive. At 350ma,
they put out as much light as a luxIII at 700ma.
The royal blue is even more pronounced compared to the lumiled's
III counterparts.

I bought a few whites and also a few royal blue ones to see if I
would make a retrofit heatsink system to use these instead of
the luxeons. Turns out it's not going to happen simply because
of packaging differences and also the light is more of a flood than
a smaller point of light in the luxeons.

As far as an efficient flood light source, they really are impressive.
They use glass lenses instead of lumiled's cheap plastic domes.
So no worries about the soldering iron accidentally touching the lens
and ruining the thing (as I have with luxeons). These are designed
to be solder reflowed - ie baked on a pcb like other SMT devices.
IMHO, much easier to incorporate into large scale production devices
(compared to lumileds) I'm sure we will start see these crees
everywhere where high flux led's are required.

Re: 60 lm/w and 100lm/w Cree presented

o there for flood? so they wont have much throw or did i missunderstand i prefare throw

Hopefully the big three LED makers will get competition from the asian clone makers and be in a war like Intel and AMD have pushing the envelope more. For now it seems like some manufacturers strife for efficiency, while others strive for production while another wants quality but none of them seem to have all three qualities figured out yet. I look forward to cheap LED flashlights replacing all the throw away incans on the shelf.

Re: 60 lm/w and 100lm/w Cree presented

Interesting 4sevens.

Also gone is the cheap black plastic that is found on the base of the Luxeon.

The packaging on these CREE parts are great, silver, ceramic, glass, silicone, gold. Made much more like a military grade part, than a cheap consumer grade package materials like the Luxeon.

And you should quit being such a jerk. Now I understand why people have complained about your postings in other threads.

The eval kit is expensive (your own words). For most folks, that makes them unobtainable. And they won't be ordering reels of 1000. I would certainly immediately order 2 of them to look at if I could, and the price wasn't super expensive.

Anyone know the current cost in lower volumes, or take an educated guess as to what the target part price in the near future might be?

Since a number of CPF'ers have had these, has anyone figured out some optics which can be used with them? Flood is nice for some things, but not most things...

Patiently awaiting another smart*ss remark from Newbie...

Re: 60 lm/w and 100lm/w Cree presented

They work out to under 10 dollars if you buy 10 or so, make certain you specifically identify which part you want..

If you buy more, at a higher quantity (forget the exact point), they get down under four dollars each.

Call ETG yourself and find out, they have been certainly obtainable for well over a month now. This has been covered in other threads.

Re: 60 lm/w and 100lm/w Cree presented

Take it easy guys.
And keep on bringing in the info please.
I'm interested. /ubbthreads/images/graemlins/popcorn.gif

 

[Kiessling]

Re: 60 lm/w and 100lm/w Cree presented

So .. a main problem might be the photon management system for those new parts, as they seem to have a different beam pattern.
Think how long it took us to find really good reflectors for the Luxeons ... almost 2 years /ubbthreads/images/graemlins/frown.gif

Threw an E-mail to ETG for prices on the 7090s. I'll post what they tell me so we all will know. /ubbthreads/images/graemlins/grin.gif
