These are 35mm optics, you’re asking about 80mm, differences there will be, but you’ll probably have better results from the MT-G2 in an 80mm polished reflector than you will get from the XHP70. This new die needs a special reflector, or at least an orange peel reflector, or optics designed to merge and diffuse the beam profile.

I was asking about the XHP-50… :~ I’m not going for sheer output, the XHP-50 will still do 3000 lumens otf, at a lower driving current, and my hope is that it would throw a bit better.

Typically, large die are not used for throw. That's why some of the best throwers are using XP-G and smaller dies. I doubt that this XHP50 or 70 will ever be throwers. Usually multiple die leds are used more for floodlights.

I have a bunch of copper goodies here! Smile

And the worries about the 12V vs 6V platform are for naught, as they sent me MK-R copper boards for the 6V set up. No funny business with airwire or resistors or any of that mess. Smile

Where are you finding those? Hilarious.

Yeah, these are nice and solid looking…save for that bit of a gap with a razor across the top. The traces are wide, looks like it should do nicely. So now I have to disassemble a light and re-flow off my rigged board and see if there’s any noticeable difference. Of course, starting from scratch it would certainly be easier to mount an XHP70.

Those are pretty fresh, they have XHP-70 on them, and it looks like a LED temperature measuring dot
I don’t get how the XHP50s work though

Bort, that’s for 12V configuration. Crazy isn’t it?

Fresh? I’ll say, SinkPAD just got this first batch in Monday. Smile

I skimmed all 13 pages looking for links, but my apologies if I missed it - Is there a source for buying the XHP70 that actually has it in stock available to order?

Mouser USA had some. That's the only ones I know of right now. Anything else is probably 5+ weeks out, before they have stock.

When I was on the Mouser site this morning it said they was a 600 unit back order, but it seemed that they had 82 on hand. I guess that means that any order over 82 they couldn’t fill anyway so why tie them up. That’s good for us that only need a few to fulfill our needs.

Mouser got those in the other day, Thursday or Friday. They had 100 coming in, two more backorders in the wings. So my 3 were part of the 18 that have been shipped out to make that 82 show up from the 100 that just came in. Smile That means I should see em Tuesday, no mail tomorrow for MLK day.

Edit: Forgot to mention they’ve got XHP50’s coming around Feb 15th. Wink All warm tint though as far as I could get from talking to em, like 3000K with 80+ CRI or something like that. I’ll be trying those as well, just because.

I have one of those warm white XHP50's, I ordered it before I got Hanks sample to test. I don't know yet what to use it for, for an output test the results are too predictable AFAIC (similar voltage performance as the cooler ones, and less output).

You’re misinterpreting a little bit. Smile Unlike other vendors, Mouser shows what they’ve got on order. What Mouser has ordered from their suppliers! If you click next to the 600 on “View Delivery Dates” it will show you when they expect to get that stock: one batch of 400 in a month followed by a batch of 200 in another month after that.

Still fine, still on a break. One day I’ll catch up with you folks! previous wight catchup Wink

Here’s a notification of the change: https://www.paypal.com/us/webapps/mpp/ua/upcoming-policies-full

Quote:
Effective Date: November 18, 2014

We encourage you to carefully review this Policy Update to familiarize yourself with all of the changes that are being made to the PayPal User Agreement. These updates will be posted at least 30 days prior to their effective date. These changes will not apply retroactively and will become effective November 18, 2014. If you use PayPal after the date these changes become effective, we will take that usage as your consent to the changed terms.

Dispute Filing Window
We’re increasing the time for buyers to file a merchandise dispute (Item Not Received and Significantly Not as Described) from 45 days to 180 days. All references in the User Agreement to “Opening a Dispute within 45 days” have been updated to reflect “Opening a Dispute within 180 days.” The Sections these changes appear include the Introduction, 3.15, 13.2 and 13.5.

And here’s the document that actually changed: https://www.paypal.com/us/webapps/mpp/ua/useragreement-full#13

Section 13.2.

I agree, this is a terrible change from the sellers’ perspectives.

OTOH it solves a dilemma faced by the nicer individuals who order from China and are asked to “wait, wait, wait” for surface mail. Often nice folks who trusted sellers were asked to wait beyond 45 days. For many people this was no problem since the packages eventually showed up. Other people were unable to have that much faith for whatever reason (burned in the past, etc) and felt compelled to file a claim at the 45 day mark. Several members here keep datasheets and previously filed a claim for any unreceived goods 45 days after payment as standard policy! This was never the intended use of Paypal’s dispute resolution system; therefore the practice was detremental to the system. In the end the 45-day limit caused several things…

  • It made it very difficult for the system to judge good sellers from bad due to the signal:noise ratio.
  • Good sellers who used slow surface mail shipping or ran into problems (like returned li-ions from mailcarriers) were sometimes wrongly punished.
  • Extra work for buyers determined not to get the short end of the stick (keeping spreadsheets, filing disputes at the 45 day mark on the dot, etc).
  • Beyond the cost of resolving disputes for packages that would eventually arrive anyway, international sellers (as well as those providing custom orders which took a long time to build) which faced another problem: many buyers were simply unwilling to deal with the risks involved with that 45-day limit.

So while for many sellers the change increases risk, there are also benefits for many. Increased buyer confidence leading to higher sales AND reduced losses through the elimination of honest but unnecessary “item not received” claims.

So yeah, meh.

I didnt read all 8 pages of this thread, but here is my update.

LCK-LED has the XHP 70 in stock, but its not a top bin.

http://www.lck-led.com/cree-xlamp-neutral-white-4022lm-n25a-p-1289.html?...

Cutter has them listed as in stock on a copper star in the N4 bin

http://www.cutter.com.au/products.php?cat=Cree+XHP70


As mentioned before the 50 size emitters will work on XML boards in 6V but not in 12V
I will stock the 70 size boards, but am not sure about the 12V 50 size yet.

In Him (Jesus Christ) was life; and the life was the light of men. And the light shineth in darkness; and the darkness comprehended it not.
