In this thread, we take a moment to remember all the diodes who gave their lives to serve our pursuit of photons.

Try to list as many as you remember, their lifetime, their cause of death, and how great they were when they lived.

PHR-803t: At least 6. 1 died at 175mA because we weren't sure what to run them at yet, and I was willing to sacrifice lifespan for power. It lasted about 20min. It was very bright. It will be missed. 2 died to broken pins. They never had a chance to shine, as I was testing a homemade host, which required twisting the module head to fit it, and the driver caught on the housing, putting too much torque on the pins. One of which I soldered the broken pin stub to the case and got it to lase for a bit, though we were still running PHR's at 150+mA at the time, so it didn't live long. The other, I flubbed by using too much flux when trying to solder the pin stub to the case, and I ended up with the entire casing wicking up all the solder, it never got a chance to shine. One has died of what I'll call "natural causes", it lived a strong and hearty life at 125mA, helped me find flourescent objects in the dark, pointed at projection screens during presentations, it had a full life and it will be missed. I've had more PHR's but I can't place what happened to them.

LPC-815 Open Can Reds: At least 10. These have been troublesome for me, I've had a number of them fail for no particular reason. At least 4 have died due to me twisting the positive pin, and the microfilament wire inside breaking off. One "died" due to me trying to break its heatsink apart, it turned out to be a softer metal, so the diode came out all twisted. If anyone needs an oval shaped LOC, contact me. At least 3 have died due to overcurrent or bad drivers. They will be missed. Their exemplary output during their short lives was enjoyed by all. One died by natural causes, at least 100 hours on it, it was one of the first pointers I ever built, and it lasted the longest. 400mA, aixiz glass, no heatsinking, though I used it every day for at least a year.

More to come...

mine are all 405 nm's I'd say 12 phr's and one 6x so far the only two reds i have done a 16x stonetek and a loc are still going strong

I've seen about 2 of this type of thread already existing.. I know you know where the search button is :rolleyes:
Edit:
Thanks for the link ColdStl!

Oops, thanks! I didn't know a thread like this was posted so recently... :yabbem:

Yeah, this is one of the things the search button will never be good at.. Try searching for "dead diode" and see what comes up :undecided:

yea but psuedo made this thread its better lol
Hahah, thanks I guess, lol :umbrella:

Man oh MAN! I thought on the reading of the thread topic you were going to say farewell to the recent 8x of yours... I was glad that wasn't the case... I'm bored too!

I started a thread like this awhile back here. I'm linkng to it so that both of them can stay together. The more knowledge we get on the causes of these deaths, the more we will understand these diodes.

LPC LOC red: died after I put three freshly charged AAAs into the holder and pressed the button. fried both the driver and the diode. nuff said :(
So far that was only build, with a lifetime of about two days :D

LPC 815 diode has died yesterday.
I have used this diode for about 1 month of regular use at 410mA.

*taps plays* The longest lived PHR that I am aware of has died after nearly 4600 hours at 90mA.. Time of death: around 10:30PM last night US Central time. The diode was in an Aixiz module mounted in a z-bolt lab-style heatsink. It was powered my an LM317 circuit with diode protection and filter caps. (It probably would have lived longer at slightly less current, but I'm quite happy with its lifetime. I'll have to start a lifetime test on a 6X next..
