Not all laser enthusiasts are from USA, here are some in Europe.
I'd rather buy diode from you for 50USD+shipping than from someone in USA for 50USD + much more expensive shipping

I don't see any difficulties for selling these diodes in Europe.

Take into account Shipping times too, diode would arrive in one week from HIMNL9, while it can take several weeks to arrive from USA.

Good points are made here, but aren't we rushing a bit?
We still don't know HALF of what we should about these diodes.

Let's see what will some test tell us...

I don't think anyone's rushing anything. The test data is a bit scattered, but we already know LOTS about these diodes from the extensive testing that has been done just in the last few days!

...Which is a good thing!

Nobody is rushing, hell no - 1W 445nm blue diodes at the cost of GGW ...

Who's rushing ?

LOL just kidding

Well, folks started talkign about distribution and redistribution.
Let's wait a bit, and grab all the diodes we can at Group Buys first.

Heck, if it were $60 for 10 mW, I'd buy it. It's about 100 times more powerful,
Speaking of watts, how is that 1W diode holding up?

I haven't heard any updates on the diode being tested at 1W, but I've been pretty busy at work.. I haven't heard that it has died, though, so perhaps no news is good news in this case.

So wait, based on yoru part about 'original output in projector >600mW'. Their SAFE and STANDARD output was >600mW? the >600mW is what was supposed to last 1000+ hours?! DAMN!!! That is one smokin diode!!!

One thing I do not understand , folks.
They used 24x blue laser diodes of cutting edge technology yet to bloom in laser market in video projector, totaling output of around 14W (!) - to get BLUE color, but a red LED emitter to get red?!

Where is the common sense in that?!

Is if they were deliberately targeting laser community.
As Mario said in that matter "Not that I'm complaining", same applies here,
I'm just a very nosy person so...

How does that fit in?

At least one explanation why the blue has such high power is because it has to do two tasks; making both blue and green light... And getting red light via florescence is a lot harder than green, so they just used a LED for red.

Default Re: 445nm Casio Laser Diode Compilation Thread

But how hard can it be just to use blue and green LEDs respectively, I think the projector cost would cut in half and it'll perform the function just as same.

Not that I'm complaining though

So if the projector costs 700$, if 600$ of that is cost of only the diodes, that means the diodes they get are $25 a piece.

So basically, 445nm 1W diode cheaper than freckin' SF-AW.

How?
Did I sleep over 5 years or something?

Not that I'm complaining though

So if the projector costs 700$, if 600$ of that is cost of only the diodes, that means the diodes they get are $25 a piece.

So basically, 445nm 1W diode cheaper than freckin' SF-AW.

How?
Did I sleep over 5 years or something?
If you contract to purchase several thousand units, you too can get those prices.

Peace,
