what comes after p7?

just out of curiosity, has there been any talk, news, leaks or press statements about the next LED to surpass the seoul p7 in either light output or efficiency? i remeber about a month or two ago seoul relaesed a statement that they were going to pass the 1,000 lumin mark right about now, but like i said, that was months ago, and i havn't heard anything large since.

so how about you guys? hear any new?

q8 I guess

i honestly thought of culling that joke before it came out, but i decided against it in hopes that it would be left alone

Geez! The P7 isn't even really "here" yet! Let's savor that for a while!!

a much smaller quad-die, wired in series, priced like the P7 (or cheaper?) using the latest die and with a bin rating one gets what payed for (because the Osram Ostar already meets the 2nd criteria)

... and suddenly everyone will apreciate all those tiny and available step-up circuits

There is the Osram Ostar 6 die LED but it isn't that much brighter then the P7(the best is around 1100 lumen at 1 amp at arounf 20.8v)

Ok where is P7 version of Cree and how about 6 dies of Rebel 100? shouldnt multi-rebel like P7 be more practical since their die is so small?

common guys/girls, this is an honest question, and so far gunner12 is the only one to give me an honest answer, i'm sure most of you know a tidbit from some where, so how about pooling your knowlege

If the rebel was ALREADY having heat problems, condensing it wouldn't be much better.

Also, Philips is having issues with the production of the rebel and the K2, so are trying to figure this out before making anything new.

Cree is probably trying to get something with less variation than 740-900 lumens before they publish it.

I really have no idea. But if you are going to use a multi die LED the shape of the LEDs should be changed to better fit the circle that inscribes them. Actually all LEDs should be round instead of square. This trades efficiency in use of the wafer for that in the light. I know what I would prefer.

Cree produces 1000 lumen single LED

The advantage of the single die LED is no need for a heavily textured reflector to hide the gaps in the multi-die LED. A smooth reflector can be designed to increase throw.

You asked a totally theoretical question, what do You want to get then?
We simply have no clue on what the industry has in work - and that small maket (just some flashlight ppl) wont have any effect on what they will build. Its home and street lighting that is important for them now.

Unfortunately I have to disagree with that "gunner gave me .." opinion.
As I knew, when typing "Osram", something like this here will be an answer:

There is the Osram Ostar 6 die LED but it isn't that much brighter then the P7(the best is around 1100 lumen at 1 amp at arounf 20.8v)

Therefore I added a total of five criteria:

1. smaller size,
2. wired in series,
3. price,
4. using actual die(s) (= brighter & less heat),
5. reliable bin rating + bin/tint choice when ordering,

where the Osrams just meet one ("in series"), just to fight that ...
... but didnt work

PS: the P7 also does not cover all of them, just to fight that post

My advise were to read any posts carefully, then decide of the knowledge/care of the poster has put into
