Cree XHP70 up to 4022 Lumens and XHP50 up to 2546 lumens - Multi-die leds.

So forgive me but it got lost in the thread, if one put the XHP50 in a 80mm reflector, how far away would the donut disappear?

It’s not so much that you’d see the donut out there in real life, but you’d see a dark central area as compared to a brighter aura. Messes with the brain, as we’re used to seeing a central hot spot.

But it will throw better than a mt-g2?

Eagle Eye X6 with XHP70 using a Minnie-M Ledil reflector making 4426 lumens at 7.45A

Eagle Eye X6 with MT-G2 using an Iris Ledil Optic making 2500 lumens at 5.43A

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.

The red 55 gallon drum is 97 yds away…direct middle of the pics.

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! :slight_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. :slight_smile:

Edit: Pics

Oh man Dale i think i have to pick up a few of those :)

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.

Oooooh ahhhhhh. I want one

Nice looking PCB :evil:

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

Here's the puzzle :

Very interesting, thanks :slight_smile:

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

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

I have some day old bread, but these have a much longer shelf life :smiley:

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.
