Future development of the maximum luminance of LEDs

Note that Osram makes LEDs that should be potentially better than White Flat:

  • KW CSLPM1.TG
  • Oslon Boost HX

For some applications KW CELNM1.TG would be better as well.

SVK, I think that Mouser simply puts in a bulk order and does not really care what they get, they just want something with maximum margins so they can see the demand. They rarely have the best bins or tints of any LED.

Agro, Interesting, what footprint are those? 3535? Do they also have a neutral thermal pad? That is what is making me consider the white flat. The black flat was just too much hassle to work with.

OK, the above may not be fully correct as it was written from memory. I now refreshed that with datasheets.

  • White flat CSLNM1.TG
    • 1 mm²
    • 3030
  • CSLPM1.TG
    • White Flat’s larger brother
    • 2 mm²
    • 3030
    • die is not square
  • CELNM1.TG
    • 1 mm²
    • 1915
    • datasheet lists bins up to 8F, 12.7% up from white flat’s 7F
  • Boost HX
    • haven’t seen a datasheet
    • 4040
    • latest greatest

The boost HX (real name CULPM1.TG) is just a larger version of the CSLPM1.TG with better cooling for more power capability.
No reason to get a CSLPM1 when the boost HX is announced.

The CELNM1 is the same thing as the CSLNM1 but with a smaller and non-square package with worse cooling. The only reason it seems better on the datasheet is because they list an extra bin, and it’s pretty much impossible to get a high bin from the osram LEDs because they are sold in ranges of bins.
It will simply overvolt worse than a white flat would, and be very difficult to find a PCB for.

Basically the second letter is the physical size of the package:
E = 1915, S = 3030, U = 4040

The fourth letter is the size of the die.
N = 1*1 = 1mm^2, P = 1.25*1.6 = 2mm^2

Had anyone tried the CSLPM1.TG yet? It looks like it’s available on mouser.

The black and white flat are cool, but they are just not big enough for the builds I’m interested in.

Edit: so this one and the boost hx are both 2mm^2 dies, but the boost hx is square?

Do you have a model number for the Boost HX? What performance do you expect? For some reason I can not view any datasheet from their site, the PDF just refuses to download.

I rehosted the pdf here : http://dl.free.fr/bUDkZF00x

It’s basically a new version of the Q8WP which koef3 tested here: LED test / review – Osram OSTAR Projection Compact LE UW Q8WP – Black Flat's big brother, very high luminance at higher flux!
CSLPM1.TG is to the Q8WP what the CSLNM1.TG (white flat) is to the black flat.

The boost HX is the CULPM1.TG, they are not two different LEDs, it has a rectangular die just like the CSLPM1.TG and Q8WP.

Just google “KW CULPM1.TG” and it’s one of the first few results, a pdf.

So when can we start expecting the Oslon Boost HX to be available for purchase?

Anyone know where to buy these? Perhaps someone like LED4Power, Richard, or Kaidomain can buy a reel and do a group buy

This is what Vinh (Skylumen.com) said about the White FLat.

Oh….

Funny, I just impulse bought 4 of the CSLPM1.TG from mouser last night. Looks like I bought the first 4. Can anyone tell me how the mouser bin compares to the ones available from led4power? I couldn’t make sense of the order code.

From L4p you can get 5P bin. From mouser - random bin from 7N to 6P.

Any numbers with this LED yet?

Jeez how is led4power getting all these super high bins… :open_mouth:
Now I need to buy this led too!

Still more excited for the CULPM1.TG though, but that’s probably months away, nothing shows up yet:

I need to update the table in the first post. It would be good if we had some actual Luminance values though.

I’m still waiting on my CSLNM1 LEDs to arrive :frowning:
I wanna see just how much I can get out of it with some extreme cooling.
7 or 8 amps peak maybe? :stuck_out_tongue:

Peak could be anywhere between 8-10A but it will easily pull over 13A without exploding on fet driver :slight_smile:

I did some classic redneck style test here

I like it. Wide screen TV 16:9 format LED emitter :slight_smile:
