I second that about Jordan. :beer:
Thanks Jordan.Yea over 8W is way more than I would expect so it is probably right that more current was getting to the diode than it should. I set these to 4.5A unless asked for a different current. I would agree the best guess based on what you described without seeing is some type of issue with the driver. I can get you swapped out but please shoot it over before taking it apart so I can better troubleshoot it if you have not already.:beer:
Just curious, your LPM shows 7.5W, is that using 3 element?Hi ,
The 444's are powerful i just built one for sale on my thread its awesome love that diode despite the divergence not bad at all with a 3 Element though.
Haha actually, my girlfriend came home from work, i told her to stay away from the office without safety glasses, and in doing so I shook it off a little bit. No it was still cool and running fine, I just assumed it's only going to drop due to heat, and I was after a max mW for a customer.Why the sudden drop at at 27 seconds... Have to ask did you shut it down because you ran it too hard?
This build is a single Nubm44 which metered 8.4 Watts. But the driver blew up in it after only a few minets runtime. DTR replaced the Module with a new Nubm44 but without a driver this time.Interesting ... so do these photos always refer to your Nubm44 from 7.2W?
Or did you combine 2x7.2W with mirrors?

When I put it together I will Meter this diode and see if it compares to the last. Maybe it metered 8.4 Watts and blew up the driver because the current was set to high when i received it.
I have also ordered the x6 Correction optics to fix the beam up somewhat.
Thanks for the update Mosc. Best wishes with your (continued) build. Like your heat sinking job. Well done.
