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

AND, the XHP50’s will be here end of next month. :frowning: Oh well, I’ll have something to play with for a little while anyway. lol

Might have to spend some time pulling my rigged XHP70’s out of lights and putting them on the SinkPAD’s. :wink: Then I can test all over again and see if there’s any viable difference with the proper pad.

Anybody seen any real leads to the XHP70/50 leds or copper stars for sale at "regular prices and amounts"? Like 2 or 3 or 4, instead of a bunch? Any word from Hank about his stars or Maxtoch about the 26mm ones?

I haven't been keeping track and probably won't be able to for a long while.

DBC has I believe some MKR stars coming and has them for sale.

RMM stated that he has some bare and mounted to copper on the way.

From Hank at IO?

He didn’t say where they were coming from.

I have 40 SinkPAD XHP70 stars coming, they were supposed to have shipped yesterday…so maybe tomorrow? Cost me $2.50 ea. and that’s what I’ll sell em for.

Richard ordered some of these from SinkPAD as well.

Edit: I’ve been snookered yet again! I was told they had a $75 minimum, “about 40 boards” and I was told they’re $2.50 ea. I never actually did that math!!! I should have 30 coming. I don’t need 30, of course, so will be spreading the majority of them out…

...between the 15 or so lights I am going to build next month. (finished it for ya)

Sinkpad MCPCBs, LEDs from IO.

I’m aiming for at least 2 or 3 a day, sometimes 4. :stuck_out_tongue: (I’ve done that before, but certainly not on a daily basis)

Can’t afford that many big emitters. Already in a hole, imagine that….

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.
