Future development of the maximum luminance of LEDs

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
Click on the box “Valider et télécharger le fichier” to download it.

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:

Wow, it pulled 13A with a single cell? That is an impressively low Vf, even the 219C 90cri only pulled around 10-11A.

How does it compare to the flat black / flat white in throw?

Same or even better in throw than white flat 1mm with more lumens and wide screen tv die projection :slight_smile:

Edit: Why I said it may be better than white flat 1mm? Because I can not measure that with mine fet driver configuration since it pulls a lot of current and thus generates a lot of heat which could have influence on performance.

Some regulated configuration in multi cell lights with better cooling potential will show real nature of this emitter.

If I would have to place a bet who would win between 1mm or 2mm White Flat I would place a bet on this new White Flat 2 mm.

Since it is not suitable for my fet driver single 18650 light configuration I am really looking forward for real builds BLF members will bring with this new White Flat 2mm.

Comparison pic between new White Flat 2mm(sorry I really can’t remember full name) and XP-G2 S4 2B DD

It’s the same LED technology but with just a bigger die.
Since the physical size is the same it will always perform worse than the smaller emitter because it has a larger die area and therefore requires more wattage to achieve the same cd/mm^2
More watts and same cooling pad area = worse performance as you increase the current.

The boost HX aka CULPM1.TG which has a physically larger size has the chance to perform better.
