    Albinoni, if you type in "Cree LED" on Google, the very first thing that comes up is the company website.

    That illustrates the point that it is always better to do a simple search (either on Google or by using the CPF search function) before asking a question or posting a new thread.

    I have already closed 2 of your threads today, but I will leave this one open for the time being so that people can discuss the other aspects of your question.
    Resistance is futile...

    I have a good friend in Marketing and they are located right around the corner from me in RTP (Research Triangle Park). Basically between Durham and Raleigh.

    Sorry but the main reasoon why I asked this question is just because Cree is a US ompany that doesnt mean its LEDs are manufactured in the US. Panasonic, Sony, Sanyo etc are Japanese but not all their TV's are made in Japan, infact lots are now made iin China, Korea, Indonesia etc. I've also seen Samsung Plasma's made in China and Indonesia. Also I can rest assure alot of Philips LED's (Lumileds) are made in Singapore.

    And to that aspect of your question, the original answer also stands: Google. Googling for "cree manufacturing location" turns up several hints, and some definitive answers.

    Cree LEDs are vertically manufactured in house. This means that Cree is responsible for every step in the manufacture of the XRE. If you break it down the Basic steps are:

    SiC Wafer production (Substrate Production)
    Epitaxy (LED Chip Production)
    LED Packaging (Putting the Chip into the LED Housing)

    currently all of this is done in Durham, SC, USA. But by the End of 2008 at least one part will be done in China (Shenzhen near HK), the LED Packaging. Cree will not be outsourcing this, they bought a Chinese packager (COTCO) and they are Qualifying the production line now. But it is not clear to me, beyond packaging, how many of the other steps will be in China. This is not insider information, as it in their 2007 annual report.

    So by the end of 2008 many Cree LEDs will be at least partly manufactured in China by Cree.

    Default I don't mean to tick anyone off...............

    ..............and especially not the Moderators, but I don't see what the big deal is in asking a question that 'could' have been answered by a google search.

    This IS a forum for sharing knowledge and interests. By reading this thread, I have now learned a bit about a subject of which I had very little previous knowledge. More to the point, I would never have even thought to ask, so I'm glad that someone else did.

    If it happens to be an old, frequently answered question, no one here is compelled to answer. The CPF search function is very useful, but certainly imperfect. Many times a helpful CPF member can easily (and gladly) provide a concise answer that hours of searching and reading may not disclose. Unless you know the precise word or words upon which to search, it is often very hard to find what you need.

    Anyway, all I'm saying is please let's not discourage questions.

    Thank-you...................Frank

    My thoughts exactly, Frank! If it makes someone a bit miffed if a simple question is asked, then that person should just simply not offer a response. In a way, CPF is a "Google" for flashlight questions. I say if you have a question, ask away!
    Aren't flashlights cool?
    Carry a flashlight, and you'll have a bright future.

    CPF has Members: 35,027, Active Members: 7,103. If all the active members ask questions with the frequency of Albinoni (27 new threads in 13 days) CPF would be swamped to the point of being unusable.

    I suggest doing the following before starting a new thread:
    Search CPF (search titles only - the search all posts usually bomb);
    Search Google (CPF only);
    Search Google (I usually use Google advanced search instead of just unchecking the CPF only box);
    If replies to a question raises another question post in the same thread. Edit 1st post and Title as necessary. I feel I am chasing Albinoni all over CPF to answer related questions.

    Frank_Zuccarini, kilgor here is a list of Albinoni's threads so far this year. You decide if following the steps I outlined above would reduce them to 1/2 or even 1/4 of the large number. The mods are riding Albinoni for a reason.

    I understand both sides of the story ... and both are correct.

    I guess that the reality is that everyone is new to the forums at some point ... it's just we hope new(er) members pick up on forum etiquette eventually and figure out what questions are "basic" and can be answered doing a quick google search and what questions are not - thus necessitating a more involved question.

    We also get semi-frustrated when a member posts many questions that have been well documented already ... but in a way it's hard to fault them if it's done out of enthusiasm for our shared hobby/interest in flashlights etc. If it's done out of ignorance ... well ....

    Unfortunately, it's not possible to lash someone with a wet common-sense noodle ... so we can't reduce our stress when most of us abide by learned netiquette.

    Oh, by the way, it's Durham, NC. (just teasin')

    Come on Guys................

    These are legit questions, even if rather newbie. I have many students that ask newbie questions, even my graduate students.......

    An effort should be made to search for the information if possible. But what if a newbie doesn't know where to start? Or what questions to really ask? -Or- what questions to really search for?

    If a people, including moderators, are so bent out of shape about some newbie questions, maybe we should segregate topics into "newbies" and "PhD's" sections.

    I have found over the years that many times a fresh set of "eyes" can break through the myopia that we PhD's develop over time, and many times can lead higher learning into new directions.

    Frank_Zuccarini, Big_Ed, kilgor, Lightmax… One or two of you are stepping rather close to the line with your comments about the actions of moderators. However perhaps if I explain my thinking, you will understand.

    1. I pointed out to the OP, Albinoni, that his question COULD have been answered by a quick and extremely simple Google search. I did not say that was what he SHOULD have done. I did it to illustrate that it was possible.

    2. If his question had been a completely pointless or frivolous one, or had been asked countless times before, I would have closed the thread.

    3. However, despite the fact that it would have been extremely simple to look up the answer, I left the thread open – because it happened to be an interesting question, and the answers (and subsequent related discussion) would probably be of interest to other members, as indeed it has been.

    4. However, as LEDninja has pointed out, CPF would be totally swamped if everyone posted a new thread every time they had a question. A correct balance has to be struck.

    5. Albinoni has an enquring mind, which is good, and he has many questions. Some of his questions have merited new threads, and others have not. This one – in my opinion - was worthwhile. Others weren’t, and those threads were closed. He is in the process of learning the difference.

    6. So Frank_Zuccarini, Big_Ed, kilgor and Lightmax, if you read my post #3 again, you will see that I actually agree with you on the important issue here – this question WAS worthy of an answer and follow-up discussion, and that was precisely why I left it open. Do you see that now?

    7. Where I would NOT agree with you is with any implication that a moderator might be getting “miffed”, or “bent out of shape” about something like this. Quite apart from that being untrue, it is against CPF rules to make suggestions of that nature in the open forum. If you have any disagreements with any actions taken by moderators, they should be dealt with by PM.

    also where's the Cree P4 manufactured and is the P4 a good LED ?
    How did you get flashaholic status when you don't even know how good the P4 LED is?

    I keep getting included as a trouble maker that is questioning a moderator's direct actions. I have not. I merely agreed with Frank_Zuccarin's post which suggested that newcomers bring a fresh perspective to things and without the original poster asking this question, I would not even have thought to google it.

    Because of him I now know where Cree LED's are made and that they recently bought a Chinese company and will be packaging them in China in the future.

    I'm now less ignorant than I was before.

    You are certainly free to run CPF as you choose. I was just agreeing with the general sentiment that new posters add to the board. Feel free to disregard.

    Kilgor, that is quite enough from you.

    Read the Rules, in particular Rule #6.

    Instead of whining that you “keep getting included as a trouble maker”, you should instead ask yourself why that might be.

    I strongly suggest you review your attitude.

    The P4 is only one bin of the Cree XR-E LED series(And only for the Cree XR-E LED series form that I know), look here for bin codes.

    Cree XR-E white LED bins in order of output/efficiency(Known right now, red = not out yet):
    P2
    P3
    P4
    Q2
    Q3
    Q4
    Q5
    R2
    R3
    R4

    Albinoni, I understand that you are really interested in this new hobby but some of your questions can easily be answered with a simple search(Google on the top of the page or the forum's search engine).

    Wait till you start modding

    By "keep getting included as a trouble maker," I meant in this thread. I have had no other issues in any other thread that I'm aware of. All I had posted in this thread up to that point was a thumbs up symbol about what I thought was a very reasonable post by another poster.

    I have to admit that I'm very confused by your attitude on the matter. I do not feel that I've expressed any kind of disrespectful attitude to merit your response to me.

    For a topic that everyone appears to agree with (posting questions) this thread has generated a considerable amount of negativity.

    Reading through the various posts, the reason that anything was ever said, was the fact that several people took offense to the response to the "newbie" question.

    I've spent some time reading Rule #6 "Whining and compaining about the rules" I've selected a couple of excerpts that seem relevant to this discussion.

    "Should we just have one big forum and you can post any topic you want in it and use any kind of language and insult other members and just generally run amok? "

    So far, in the posts that I have read, the language has been controlled, with no personal insults being levied.

    "The moderators and administrators of CPF are around in order to keep order. Do not whine or complain about the rules and do not abuse the moderators or administrators for enforcing the rules." It is very disruptive to the board when gripes take over a thread. Take them off the board in either private messages or email

    Keeping order is generally a good thing. No one in this thread was advocating anarchy. Nor was anyone advocating abuse towards a moderator. Nor was any abuse levied against a moderator.

    However, there was objective criticism in how the original poster "Albinoni" appeared to be treated. As an offer of proof and clarity, I have attached the public posts that probably were not as professional as they could have been.

    1) "I have already closed 2 of your threads today, but I will leave this one open for the time being so that people can discuss the other aspects of your question. " (DM51)

    2) "Where I would NOT agree with you is with any implication that a moderator might be getting “miffed”, or “bent out of shape” about something like this. Quite apart from that being untrue, it is against CPF rules to make suggestions of that nature in the open forum. If you have any disagreements with any actions taken by moderators, they should be dealt with by PM." (DM51)

    3) "Kilgor, that is quite enough from you.
    Read the Rules, in particular Rule #6.
    Instead of whining that you “keep getting included as a trouble maker”, you should instead ask yourself why that might be.
    I strongly suggest you review your attitude." (DM51)


    I think that it would be fair to say that quote #1 precipated the numerous posts from other members. Should this post (quote #1) been a PM? Yes. This public post did not come accross in a professional manner.

    Quote #2 came accross again as very strong, holding very tightly to Rule #6 "Whining and compaining about the rules". As far as commenting on a moderator possibly being upset with a poster, I call them like I see them. So did several others.

    Quote #3 was clearly a personal attack that was broadcast into the public realm. Where was the private mail on this? Does rule #6 "Whining and compaining about the rules" apply to everyone?

    "The mods are riding Albinoni for a reason." (LEDninja) Again, here is a sentimate from a public post, referring to a perception that the original poster (Albinoni) was under scrutiny by a moderator, public in nature.

    Furthermore, It's not solely my opinion that there was a issue with professionalism.

    "I have to admit that I'm very confused by your attitude on the matter. I do not feel that I've expressed any kind of disrespectful attitude to merit your response to me." (Kilgor)


    Everyone should be treated with professionalism, in both directions.

    I believe the original question of this thread has been answered. The other discussions can be addressed in a PM, so it looks like this thread has run its course.
