who wants to tame this?

Posting to track.. and...

...It's all going to come down to the quality of the show, and to be honest whilst there are a lot more people here doing the ass end shows, very few of them do good shows..

it says iop div shift.... what is missing?

The info is also incorrect for max amperage. The newest sheet has it at 1.8a from tech hood

$880 USD .. the price is dropping slightly ..

PB- you got a link to the tech hood spec sheet?

This is like water torture. They will keep dropping the price until people begin to bite. This will then slow the descent. I think it will still be a while before these approach the $300 range where I would buy one.

Yeah, if Nichia wants us to do their beta testing for them they need to throw us a bone .. $200-300 is my price range too ..

Something that I find interesting is that Nichia is a Japanese based corporation and although they have offices around the world all of these offers for this new diode are coming from China: all of them! Now, I am not accusing anyone of criminality (yet) such as "these must have fallen off the truck". But, consider that these multiple sources with unknown ties to the manufacturer are unlikely to represent a local Nichia sponsored release of their new product. If this was the case then there would more likely be sources distributed around the globe and these sources would have a traditional relationship with Nichia. My theory is that the actual release of these diodes occurred months ago, maybe many months ago and large quantities of these diodes were produced and shipped to the most likely location for integration into consumer video projectors...China. Inventory control at these OEM plants is sketchy. A few trays of these diodes found there way to alternative distributors at an early release, premium price.

It has been discussed at length what is the necessary RGB power mix to produce a "balanced" white. But, a reasonable argument can be made that the power of the red and blue should not exceed that of the green by more than two to one. The laser based video projectors that are a source of even the more powerful 9mm 445nm diodes have something like 12 diodes running @ about 1.4W each. This suggests that the typical green diode installation will include at least 6 and maybe a few more of the 1W, 520's. Because a manufacturer that is currently utilizing blue diodes is more likely to add the greens than to replace their HID models with a light source that ONLY has green diodes, a single projector may soon yield both colors when harvested. There may also be increased incentive for more manufacturers to move from HID to laser with the additional color available. This is certainly more likely than the reverse. The price point for these projectors has to remain acceptable to the general market because it is not the laser enthusiast that makes the market its the sports fan. The enhanced appeal of a second laser source within a projector that can already be marketed as a "laser video projector" will be small.

Bottom line is that as soon as these projectors are released then the cost of these diodes will drop precipitously. That is when I believe the bulk of the work with these diodes will begin. Being willing to discover how hard to drive them will require destroying a few and the BEST optics to collimate and combine them will take more than the work of a single researcher. Despite the "Christmas is coming" anticipation, I think we should just wait.

I have it on really good authority that these are going into ultra high end projectors, and just a handful per projector. Think 3D movie theatre.

Not yet ready for prime time home use. They might be as much as two years out.

Steve,

By the way nice review of the 506's. I am looking forward to using some of these with their dedicated "credit cards" ASAP.

Regarding your thought on the release of these projectors. I am not convinced. The really high end projectors from companies like Christi are going to continue to need HID for the red component. I also think that this proliferation of wild west suppliers for these diodes means that the sources have to be pretty numerous otherwise heads would roll for missing inventory for very small runs for projection systems for Disney and Dubai etc. O-like, just one seller, claims to have one hundred in stock.

Another way to think about this is this guy from aliexpress will sell 5 of these for $690 (each) and at that price he is still making a profit. The price is already dropping faster than gold. One possibility is that he (as with the other "sources") is aware of the limited time before general availability. The very fact that he has them suggests he has some information that we do not. He at least has contact with a source that has insight into how to get these and this is guiding his price. He did not drop his single piece price, say just $5 below other eBay sources.

I agree that release will be slower than we want, but looking back on the 445nm diode how long were the super expensive diodes dribbled out before the flood with the first Ca$$eos were released? This is not rhetorical, I really don't know as I only got involved in this hobby 2 years ago.
