I have an 8x BR diode harvested from an LG-BH08 bluray burner. As far as I can tell it was the first one ever harvested on the forums. I've been using it about a year now, and have treated it as gently as I can. One way or another, either through improper heatsinking (unlikely), bad drivers (somewhat probable), or just plain bad luck (definitely possible), it's gone and "degraded".
It now projects a disgusting black halo around the centre of the beam. Check this thread for some pics: http://laserpointerforums.com/f38/8x-br-diodes-42806-8.html#post661598
This seems to be a (somewhat) common way for 8x diodes to fail, it happened to misterwilling as well: http://laserpointerforums.com/f38/8x-diode-degradation-42088.html
I'd really like if someone out there with the proper equipment could take this off my hands and tell me how and why this happens. The most this diode was exposed to is 1minute on at 350mA in a jayrob sidebutton host. I noticed this behavior after I transplanted it into a whitefusion build at 300mA. As far as I know, it's never been treated badly. I always try to ensure things never get the slightest bit warm.
I've offered this to IgorT, but he never responded to my PM/emails, so this is up for grabs.
The first person who can reasonably convince me they have the equipment and knowledge to properly test this, can have it. If you live in Antarctica or the ISS or someplace, and you want super duper fast same day shipping with signature confirmation and DNA test, I may ask you to pay partial shipping, but otherwise the diode is free.
