That's awesome. I've only pushed them a little past 5 amps and haven't blown one out yet. They are definitely tough. I'm getting a 20 or 30 watt LPM This week. The one I sent to Flaming Pyro I don't think hes tried it yet. He's always away doing stuff. These diodes are definitely the closes thing to the NUBM44 that are redily available. I really like the beam produced by the Gball also. Do you see what I was saying about how it doesn't cross over its self? It just goes strait out. It wouldn't take much in the way of optics to make it perfect. Plus I'm guessing that gball has a pretty high efficiency being that it's AR coating is matched to this diode.
