6W NUBM44-71/NUBM47T
7W NUBM44-81/NUBM47-A1
450nm Laser Diode
Title subject to change when/if new testing data changes
UPDATE
7W+ NUBM44-81/NUBM47-A1 450nm Laser Diode
The 6W+ NUBM44-71/NUBM47T the original version of this diode has been out of production for about a year now and the diodes in the projectors now in production carrying the same base designation are of a higher efficiency than to the previous but with identical beam specs so more likely just a different bin of the same production. The serial numbers on the new blocks are NUBM44-81/NUBM47-A1. They will do 7W easy and can push past 8W. The new 7W NUBM44-81/NUBM47-A1 test out more efficient and the guess is that the projector company was more after a specific wavelength bin. Efficiency and wavelength tend to be inversely proportional when diodes are binned. Reports from a customer of mine that batch bins them for wavelength is showing wavelength is slightly lower by several nm on average in these new batches closer to 445nm than the older batches from the previous version which were up around 450nm. From what I hear they get better reaction near 445nm with the pospher in the projectors to make green light.
Anyway probably just call them NUBM44-V1 and NUBM44-V2 to keep it simple.
For Clarification
There is some confusion that the power difference is 44 vs 47 which is not correct. It is 6W NUBM44-71/NUBM47T vs 7W NUBM44-81/NUBM47-A1. 44 is a 8 bay block and 47 is a 10 bay block. !!Also so there is some way to know what you have if you have purchased a NUBM44 from me in the last six months this new version is the diode you have received and a mixed chance for it being either a V1 or V2 version going several months back of that. I mention as I have had a lot of questions about if the diodes ordered recently were the V1 or V2!! Also of note there are a lot of the projectors with the V1 diodes that are being retired by organizations currently and computer shops pulling the blocks of these stockpiles and shipping them off to china or even units being sold as whole in lots to sellers. Like the M140 variants, NDB7875 diodes and some others there are now a lot of used V1 versions of these diodes being pulled from used or EOL units.
So here is the new bad boy on the block. My meter does not read past 6.8W but this diode is clearly doing well over 7W but I will call it 6W till someone can show some testing further than I can with my meter. In this video I show how my meter is maxing out. @ 4.5A it does 6.8W and I ran it for about two minutes @ 5.5A with the meter pegged at max the whole time never a drop in reading so there is a very good chance it is doing much more than that.
So there you have it more data to come along with some wavelength testing.:beer:
