Is there a big difference between the NUBM44-V2 and the NUBM47-A1?

Is there a big difference between the NUBM44-V2 and the NUBM47-A1?

Funny enough there was never a "V1" or "V2" just different sources.
Only NUBM44-61, NUBM44-71, NUBM44-81

For the NUBM47-A1
The "A1" represents "A" in hex base-36 is "10" (x10 diodes) and "1" (x1 module)

But to answer your question the typical wavelength of the 44s is more towards 440-445nm while the 47s is more towards 450-455nm. The power or efficiency of the 47s is greater than the 44s

How difficult is it to remove the diodes from the block?

Not hard with right tools I can sell the whole block or i can extract the diodes for buyer same price.

Thank you for the great information Darktron. Is there a way to distinguish a 44 from a 47 once they're removed from the block? I see nearly every LD seller using 44/47 interchangeably in their advertising. Is one of the two available in more abundance than the other?

44s is more abundant currently but depends over the years one can be more than the other.

Only few that have had many of them in hand can tell the difference. But you'll want a microscope to tell for sure.

Here can see NUBM44-71 vs NUBM47-A1

Yeah I have a microscope. Not much good unless the LD is decanned though. For these photos, I'm sure about the NUBM07 but not the one I think is a 44.
