Well... I built a quick little box style the other day with an open can PHR-803T diode. Just for fun I guess. I had it set at around 120mA. Well, today I changed the lens in it and went to turn it on and it flickered and became an LED on me. I checked the current and somehow it crept to 145mA. No idea how.... Anyway, since it was dead I decided to see what would happen with just a little more current, and suprisingly it lit right back up again ;D The beam itself directly from the diode has some weird 'veiny' patterns in it now, and its obviously not as bright but I still thought I would share ;D ;D
But this does give us a bit of valuable information. ~150mA is too much for this diode to handle. So to live on the edge I would say about 115mA would be the highest I would take these. and not over ~90-100 for a decent lifetime. It didn't even light up all the way for a few seconds before dying. Even my 6x at 280mA lased for about 5 seconds before dying.
This also leaves me with some questions. Since this was an open can, could the spring in the aixiz module have hit something and messed it up? I used the laser for maybe 5 seconds yesterday as a camparison with my 6x and it seemed fine. Then today I swapped the lens out before using it, and it dies. So who really knows?
All I know is that I will enjoy the last bit of lasing that my zombie diode has left, and then lay it to rest with all my other brave, fallen diodes.
EDIT: thought I would add something else that is noteworthy. The zombie diode has the 'yellow' around it, but it also has this weird greenish-rainbow cone stemming out from where the spot would be on the die (since you can see the entire image of the die as an artifact now) pretty cool!
