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

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.
