Really nice builds I got 9.5W or so 5A rated driver NUBM0F this one is S8 but is same design slightly longer. Is a full copper side and back (LD base) with just a slot for the wires very similar design similar to the LD banks. I do use thermal paste between the LD base and heatsink since I don't...

I was about to say a S21G wouldn't have enough mass for how much power you're putting into that array. That was the problem I ran into with S2+ builds I did touch 9W+ but had to keep duty low to allow for cooling. That's a Monoheatsink or MHS is what I called my design coming in at 57.5 grams of...

Yes it would surpass the NUBM0G which comfortably sits around 8W overdriven.

Binning list for Osram PLPT9 450MD_E

To make this clear for future reference this diode specifically is PLPT9 450MD_E (E9633) is a example bin as these 450MD_E will be sold from different bins. Such as PLPT9 450MD_E (B64B70) this one is less powerful but the wavelength is closer to 470nm

Winner winner thanks for testing 😎

Dual emitters, quad laser diodes very nice

Not me unfortunately... They have shown them in exhibition at shows but I haven't been to any at all.

I eventually got a proper LPM Sensor and is way faster and I can also read higher outputs with the same or better accuracy.

You can achieve a decent LPM with some specific peltier modules (not any) and a fast and accurate ADC. My LPM is based on esp32 (not the best ADC within but it was enough). And a 3v or 5v peltier modules can't recall exactly model atm. Some good matte black paint. The beam had to be unfocused...

For QuaLas arrays specially the dual stack ones I recommend physically splitting the arrays and powering each with their own driver at lower fV but is not an easy task to split the arrays.

I want to point out the Sharp GH04C07W9GH (7W @ 435nm @ 3.8V @ 3.3A) according to the preliminary datasheet specs this diode can have a slope efficiency of 2.41W/A (the NUBM0F only has 2.03W/A) so this new Sharp diode could well be a 12W diode at 5-5.5A

Just want to have a small-medium collection of blue diode diodes that are rated around 6W+. Feel free to add to the list but remember the minimum requirements 6W+ rated, 430-490nm, voltage, current, all of these should be typical range in datasheet. Multi mode, single, dual, or triple emitter...

This seems to be a higher bin of the "Monster" (PLPT9 450) diode😁 7W @ 3.7-4A probably an easy 10W+ at 5-5.3A

Yes they are for sale but I can't justify the price is a bit more than the nichia ones.
