I won a NUBM0AT at auction and tested it with it's GBall intact, I expected it would be a NUBM08 as the new designation is a mimic NUBM0AT as in Ohh Ate Tee.......anyway it comes on the new thin backing plate and at 4.5a is doing 6790mw, it looks like 450-455nm

So these are putting out NUBM44 power in a brighter blue 450-455nm, too bad about the GBall but a backwards then forward G2 would let it run GBall intact and could be corrected via cylindrical pair then focused to a tight useful spot.

I have not pulled the can yet to check the natural divergence, but I expect future diodes will get even stronger and will likely be in this format, the spot out of the GBall makes a 25mm x 6mm bar at 2 meters, there may be some that focus better depending on the natural divergence, it's a strong burner on the desktop.

That is great to see. Just wish we could get them without the ball lens. I don't mean with the lens removed, but in a TO-5 package with a regular window. Thanks for the information. I wonder what the wavelength is as you said it is higher than 445nm.

What's presented here as the spec sheet says typical is 455nm : https://www.ebay.com/itm/NICHIA-NUB...612758&hash=item2145e0ee97:g:kqkAAOSwUPZbO1Z8

With the GBall intact we can use a backwards G2 followed by a forward G2 ( focused ) and then a C-lens pair, it will cost 10% to keep the GBall and for the extra G2 but will allow the diode longevity. As these get stronger we will no doubt be doing that if no stronger window can diode replaces the 44.
