Osram Oslon Boost HX

Yeah, a lot. I still think it would sell, but that’s a significant amount sunk for a while.
BTW some further notes from the datasheet:
Osram offers tints as warm as 4700K. But the warmer ones get above BBL. To get pure white one needs to go to 5600K. Cooler is below BBL.
Charts end at 8A. Actually you’re allowed to pulse it at that current as long as temperature doesn’t exceed 104 C. And as long as pulse length doesn’t exceed 0.001s. :smiley:
If we take the manufacturer’s 1400 lm and scale that to 8A we get 270 cd/mm². At still good 62 lm/W.
But the LEDs are cold-binned. Increase the temp to 85C and you’re back to 240 cd/mm² at 56 lm/W. Still not really bad.

There is a good chance, that RS Online will sell them in a pack of 1 to 5.
(Basically the sell a wide range from Osram Opto, compared to other large seller.)

Actually, DTP 4040 looks almost like a perfect fit:

You can see in picture DTP version of 4040 on the left, and mosX version on the right.

mosX version is "the real" one, DTP version has narrower central pad because DTP technology has its clearance limitations between DTP pads and top layer regular copper pads.

DTP 4040 has 1.9x4mm central pad dimensions, A,K pads are 3.7mm tall, and overall footprint width is 3.7mm, this is almost perfect for SX, much better than XP.

I will try to contact my few distributors regarding this led, and maybe start a group buy, since I already have DTP boards

Well, that’s good news.

Are your DTP boards made of one solid piece of copper like Sinkpads and Noctigons?

Yes.

That is settled then :slight_smile:
Now for the leds and we’re in business :heart_eyes:

waiting for the test :slight_smile:

You’re amazing, thanks so much :slight_smile:

Yaaaay! :+1:

Yes Led4Power… Go for it…

This will be ultra thrower for sure and I really really know that. No need for any special testing I guarantee that to whole forum :wink: :+1:

BUMP this topic to create more demand, which will help getting these (well, hopefully).

Thinking about this emitter, i have several lights waiting for this kind of LED, some of them for years already…

But i guess it is just a matter of time. :slight_smile:
But we were all a bit worried about the flip chip trend, i guess.

Hope to see some warmer tints soon too.

I want green one :beer:

Maybe wait what Cree will come up with? :smiley:

You mean like XHP35.2? :person_facepalming:

It’s sad to say, but I don’t have any new build plans for a Cree emitter (s). The last was a triple 50.2 and before that a quad 70.2. Just toys and shelf queens. IMHO, ~80cri NW HI emitters from them are the only things I might buy more of anytime soon for gift lights.

The present and near-future of my interests are practical builds. For me, that’s hiCRI arrays running sustainable currents in mule headlamps or Carlo tube lights and pocket throwers utilizing Black Flats. If these turn out as expected and help resolve the pencil beam issue of the BFs then paint me happy! Hoping to see these soon!

To quote Driver:

I just found something:

Application Note No. AN131:

Osram Application hints for high-current LEDs valid for OSLON Boost HX (KW CULPM1.TG)

It shows the internal structure of the LED and that one (obviously) shouldn't use non-dtp pcbs.

Also, I found some precise values regarding the luminance (these are stated in the product filter/selector):

At 6A and 1670 lumen the LED gives off 553cd which means the luminance is 278cd/mm2 (just divide by the die size - 1,9875mm2). 1670lm is at the center of the possible brightness range of the possible bins when the LED is being driven at 6A.

The luminance based on the lumens: 0,167cd/mm2 per lumen (scales linearily, just multiply with any lumens value to get the luminance at that specific brightness)

I’m not really good in this. Does this imply that the Boost HX has 2.7 times the luminance of even the KW CSLNM1-TG ? (based on the numbers you just posted in the KW… thread)

(edit: maybe the drive currents can not directly be compared)
