120mW 638nm for $10.99 on the ebay including other Powers. :eek:

What if it turns out to be a 650-660 300-500mw? Still good for that price. I dunno what to make of this, but one thing that guy sells ALOT of random stuff on his ebay page. I mean he has 59 pages of stuff. Who knows were he could be pulling stuff from.

If you type in Diodes Under his store he has something like 150 listings. 445nm,405nm, IR etc.

Yea I dunno I'm thinking these are either a misunderstanding on part of the seller/supplier and/or some of these are true to the spec like lower powered 638s. I can't see this guy lying and trying to scam on purpose. His feedback is too high and too many people have bought diodes from him and never had serious issues.

Just FYI I ordered a whole batch of the 200mW 638's a few days ago.. And I have both a spectrometer AND a LPM... SO we'll see what I end up with.

My guess is they're typo'd 658's. Though the typo might have happened before this surplus reseller even got them.. Another possibility is that they are indeed 638's.. but they're large emitter 'flashlights' which will be useless to us. Or they could be some other diode all together. Nobody knows until people start getting theirs and testing them. I think the warning in the OP is a bit overzealous though. Maybe i'm just cynical, but to me it translates to 'Wait until I get mine and test them to give me a chance to try and buy out the seller first if they're legitimate and good'. People should be allowed to take chances if they damn well please. heh.

Ahh. Have you searched Ebay my friend. There is So many for sale.

Did you read any of my Updates and Post.

Why would i post this thread if i dint want to share.:thinking:

I was Just trying to warn people. Why have alot of people buy them and turn out to be Crap or not what they should be.

I dont know your way of thinking but if really wanted to keep them all to myself i would have never posted this.

Very upset at your comment.!

I will take it down...

I told you. I'm just a cynical old fart.

I generally see the worst in everything.. Though in general, i'm not often proved wrong about people's motives. Which is probably the reason why i'm highly cynical now days.

That message in your OP, coupled with you going through and removing auction links from all your posts previously... just sent out entirely the wrong message when I read the thread through the first time.

Seems you are the only one that Sees it that way.

I pulled all the links because i dint want to see anyone get burnt. Which i made it very clear in alot of Posts. Did you miss those comments.

I think that would be the smart thing to do on this. The deals seem to good to be true. So why risk it.

I would rather be the one getting burnt then say 50 people that ordered them because i posted about it. Then there will be 50 people Pist off.

Maybe not at me but because i posted it i would feel bad. You Might or others might not feel bad but i would be upset.

Iam the last person you want to look at like that.

I guess only those that dealt with me know the type of person i aim.:na:

We talked a few times and i think you know iam very Nice.

But i think i made it clear many times why i took them down.

Iam Not looking to Hog or keep all of them. Why would i, There are alot on ebay and my pockets are not that deep. Plus i did say they will be for sale for a wail.

Usually when new diodes come out there are only a few that buy them for testing. If they check out then everyone goes and buys. That is usually how it works. No.?

I dont think my warning was to much or do i think that me taking away all the links was my intention of Keeping them all to myself.

I would rather have a warning up then not. But i took it down if you felt that was what my intention where.

Edit:

DO you want me to put the links back too.?

I agree with Qumefox.

Well - not about any of the malicious motive stuff, or the theory about you plotting to takeover the world of 638nm diodes.

But I agree with the general sentiment that people should be given the information. It's their decision to make. By removing the links, you're sort of saying "I am in a better position to decide whether you should be purchasing this item, than you are", or at the very least "I don't think you should purchase this, so I'm going to make it a bit harder for you, by removing the links so that you have to really hunt for it"

Either way, I think it's a bit patronizing. I know you had good intentions, but I think information / knowledge / details should be made available to everyone. What they decide to do with that, is their own business.

I jumped on two of the diodes after I saw this thread. I'm ok with gambling away $40 on a longshot. If I wasn't, I wouldn't have ponied up the cash for such a purchase. Anyone who would be "pissed" to find these turn up as boring 660s, shouldn't have purchase them. To be "disappointed" is fine, but to be "pissed" is inappropriate - they should have avoided this of their own accord.

it's just like buying a "583"nm laser from dinodirect...
it was 532.

Really.:thinking:

I clearly state that my intention were so no one else gets burnt.

If you see that as iam calling myself better then others then Not sure where that is even coming from because i took away 3 links in the OP and then put up a Warning.


Yes the information should be there but if its a potential scam i dont want the links up in the OP. So that is why i took it down.


How many times people buy diodes first for testing then if they check out then more people buy.

So i guess those that do the testing are better then everyone else.

I think you guy's alway look for the bad. Not cool.

I disagree.

I WILL admit that I think it is fairly likely that these won't be what we're hoping for.

However, there's at least some reality feeding a bit of hope into the equation for me.

REALITY #1:
We know that the diodes listed here actually exist. IE, there really is a 500mW 638nm 5.6mm laser diode out there. It's made by Mitsubishi, and it's about $350 to buy on it's own.

Last summer, around this time, 1,000mW blue 445 diodes existed, and were about $450 to buy on their own. Then, overnight, they were ($800/24) = $33 to buy on their own.

REALITY #2
At least one of the sellers has a good track record with harvestable diode sources. I ordered six 12x 405nm sleds from buyhubforu this year, on a few separate occasions. They got as low as $30 each, at a time when all of our community/trusted stores still had them at $55, and even Glenn's groupbuy was still at $48 or $45 (if memory serves).

Of course, the information that the seller has could still be wrong, but at the very least, I don't think this is a case of a seller trying to mislead, or just being "generous" with their specs to draw in customers.

lazeerer:

I think you misinterpreted my tone. I wasn't suggesting that you had bad intentions, or any sort of ego about this. I know you had GOOD intentions.

I simply think everyone should make their own choices about whether they want to jump in on a risky purchase early, taking the gamble, and thus having earlier access to a potential "windfall", or whether they want to play it safe and wait.

That's all - I say, let everyone decide for themselves. Simple. Easy. Fair. And no guilt on your shoulders. It won't be a "burn" for anyone who has made the decision wisely given their own circumstances.

OK Guys got another update. THis Time from e_station witch is who i bought the 120mW one from>

I basically said to him that iam excited to get this diode and that if they check out you will get alot of orders.

Here is the response.

thank you,i will compensate your loss if the laser diode is not as description,thank you.

So it seems that they are sure they are what is listed.

At least this supplier said more or less if they dont check out ill take care of you. Hopefully he fulfill this if they dont check out..

That's good. However even if they are the correct wavelength/power they could still very well have huge emitters, which equals 'flashlight'. They'll still be neat to play with though.

If they do turn out to have decent beam specs as well, there will likely be a lot of people happy, and a lot of people mad, lol. Especially those who just forked out large sums recently for high power 635's for projectors.

Though just knowing what diodes are out there and available.. I'm still expecting the 3 I ordered to have something about them that renders them unusable for pointer/projector use.

It strikes me that if we want to track down this phantom consumer-product implementation of high powered 638s (if there is one), we should be looking primarily at japanease products. With mitsubishi leading the reds, and nichia leading the blue/greens, that's where we'll see an all-laser projection product first (in all likelihood).

Heck, mitsubishi actually makes projectors. Has anyone checked their lineup to see if they are boasting any laser-lamp units?

With the fiasco from 'our primary blue diode source' they might not blatantly advertise it for legal reasons. Though I do know Mitsu does have at least one laser DLP tv line on the market. Though they're far from cheap. heh.
