I bought some of these from Techhood.

The package was smashed during transit but I was able to salvage one diode even though the output window was smashed and pins were pressed so hard they almost cold welded to the diode casing. (Ringo?) did immediately take care of the issue after I posted a complaint to him, kudos to him for that.
Anyway, coming from a NUGM03T that has been pushed beyond what should be possible she finally gave up the ghost. Decanned from day one it lived for almost 3 yrs. I don't recall the current, I was at a known 1.8 for a good amount of time then switched drivers, I want to say almost 3A. No LPM(sorely needed) just a variable PS and my eyes digital multimeter and a test load. It stayed like that for a year or so with extended duty cycles. Got greedy, I cranked the current a little more and I popped it. it suffered a strange slow gradual death. In hindsight, its behavior was probably the copper bond wires melting one by one then poof.
I was VERY impressed with the NUGM03T so I wasn't expecting much from the lower cost, more conservatively specced" Sharp. I'm driving mine at slightly over the recommended 1.8A at 2A. Off the bat, the first thing I noticed even without a side by side is the color change. To me it's more green...Color is weird but yeah greener. The second was the clean output, a very defined spot and its divergence are identical to that of the NDB7875 445nm using the same distance /same lens. I know the NUGM03T is supposed to have similar divergence but I swear the Sharp has it beat. Really nice divergence!
Again, nothing to give any solid power output numbers to. My eyes are happy. It burns if that helps. Lol! Unfortunately, I never connected this diode to my power supply to find its knee. I had a driver set for a known 2A and soldered it straight on. I'm willing to believe there is some more headroom in PO with this diode as I'm not wasting much heat, it's running pretty cool at 2A.
This diode is a must-have IMO. Compared to when the first 532 DPSS greens hit the market we are living sooo good, this power for this cost would have been megabucks. Can't beat that DPSS TEM00 but this is pretty good IMO.
I still remember hearing tech bloggers say once a direct green diode goes commercial we will all be having pocket projectors... Where are they???
