Default New 465nm diode

Has anyone tested the new can/window 465nm diode?

It is not a Gball like the nubm07e but it's divergence is 13/46 and the NDB7875 is 14/44 so this should be about half as divergent as the nubm07e without it's Gball.

Looking at the 7A75 the data sheet is almost the same......something is not adding up here.

Has anyone tested one yet?

Hopefully it goes down in price. Also I wonder if it's a bit more like the 7675 and can be pushed hard to bring up the WL.

And what is this? It is nowhere writen anything like NUBM07 or so!

EDIT : OK, I think it is NUBM05t: Datasheet seems to be exactly the same.

Default Re: New 465nm diode

Center column "TYPICAL" is 465nm vs. 455nm, what struck me was the divergence was near the same as the ndb7875 that is half the line width of the 7a75, however the specs on the 7a75 data sheet for divergence don't reflect that, but this is a brighter blue wavelength than the 05t, I am curious if it's divergence is better than the 07e diode without the Gball.

On a side note I have been using the NUBM06 diodes and they have divergence like the 7a75/05t and seem really strong, likely the lower divergence adds a lot of burning potential, but you say you run the 05t at 5.0 to 5.5 amps, I don't see why the 05t would be any stronger than the 06 but DTR's test numbers fall a little short of your 05t numbers....could efficiency be improved yet fold back and total output are reduced?

I thought the 05t was just a Gball 7A75? Shouldn't the NUBM06 be an upgrade to the 05t?

Here the 05t is listed as a 23w block, I think this is wrong, that's the 07e number.

Here the 05t is listed as a 30w block.
http://www.ebay.com/itm/NICHIA-NUBM0...8AAOSwNSxVadfq

The 06 is listed as a 32w block.
