I see. But the thing is, from Cassio's point of view it is MUCH cheaper to buy a bunch of same diodes and power them at a lower current in the lower rated projector. So it would be unusual if they were different unless the A130 projector was made first, and by the time of the A140 better diodes...

I forgot to mention something about this, altho by now it's a moot point... The diode that started the S03 madness (the so called freak), which Dave sent me for a re-plot and i was supposed to return to him afterwards. Well, it wasn't really a freak. I put it on my Diode Analyzer and set the...

I believe so myself, because of the accelerating drop in efficiency after the peak. Here is an Efficiency Plot for the same three diodes. Efficiency is plotted against Pe (electrical power going IN) and shows the percentage of how much of the electrical power comes out as light: I believe...

I see, i've seen setups like that with an even larger number of diodes than in the pic ElectroFreak posted IIRC. But i didn't know they were called that. I do believe you should be able to get ~2W, whichever way you go, since the diodes appear to be relativelly consistent and two at 1.25A would...

Thanks! :yh: What's a knife edge kit? Something you designed or something available on the forum? I heard of a kit DrLava had planned, and it mentions TECs. I do believe these diodes would benefit from a constant temperature setup... That beginning of a "knee" at higher powers could very well...

My hand's been fine for a long time now, and actually it was just a minor nuisance in comparison to the main reason i was away for so long. But the gory details are too personal for me to discuss in public, so let's just leave it at that...

Possibly, if time and finances allow... But once i do, i'll have enough data to create a lifetime approximation curve, like i did with the 8x's but was unable to repeat with 12x's as only one played along... Umm to be honest, i had no idea there were two types... :yabbem: All i know is that...

I believe your 8x will live much longer than that. While i ended up testing the best case scenario here after the two low efficiency diodes died, my 8x Murder Experiment tested the worst-case-scenario. Since the 12x experiment confirmed that high efficiency diodes can survive higher powers...

I heard there was a lack of PIV plots for these new diodes... As it happens, i just made a triple plot yesterday. EDIT: The diodes came from an A130 projector, if it makes any difference at all.... This was actually the first time i had to switch my faithfull OmniDrive Diode Analyzer (TM)...

Thanks! As for the percentage... I tested only five 12x's personally. Three out of five were exceptionally good diodes with a slightly varying slope efficiency but identical absolute efficiency. From the other two, one was slightly below average, the other had an efficiency lower than many...

I forgot to mention a couple of things in the final report... From the beginning, i kinda expected the diode to fall somewhere in between the two 8x lifetimes, partially from the (failed - due to the burn-in effect changing the conditions) initial degradation rate comparisons but mostly from a...

A couple of weeks ago the body of a diode was discovered. Dental records identified it as a 12x. The autopsy revealed - it had been tortured to death. The full autopsy report is attached below. This is the final report for the 12x Murder Experiment (Take 3). The third 12x diode died, but...

The diode safelly reached 100h @ 600mW! Here is a combined re-plot for 60, 80 and 100h. Degradation @ 600mW initial Po (100h elapsed): After 100h of 424mA degradation is becoming quite noticable by itself. The power dropped by almost 4% to 577mW (96.167% of initial). I missed 100h by...

The diode made it past 50h, currently nearing 60. After 60 i'm spreading the tests out to 20h, because not that much is happening in between. The resolution of the rest of the test will be same as it was with 8x's after the starting hours... For now, here is a combined report for 30, 40 and...

If your 12x diode tests in the higher efficiency end, i believe it's safe to go as far as 600mW. Right now i stopped it at 30h of 600mW for a replot. That's on top of 18h at lower powers. Chances are good it's gonna surpass 50h and go much further at this rate, so the final result will...

Well, the diode reached 20h last night, and did something unexpected. At 424mA i measured a Po of 597mW, which is where it was at 4h! Basically, it now produces more power than it did at 10h. Here is the degradation rate plot: Thinking back to 8x's, they did this too, only with more...

The diode is reaching 20h seemingly very easily. Only 37 cycles to go. If nothing continues to happen with the same intensity, i may wish to spread out replotting to 30h intervals after this... Or i could just measure the 424mA Po instead of doing a full plot, since i would like to see what...

The diode reached the 10h mark and everything seems just fine.. I measured the 424mA power at 595mW. That's 99.17% of initial Po. Here's the Degradation Rate Comparison plot: And of course degradation is at it's slowest so far. So tired of having to say that. I wanna see some action or...

Thanks Jay! Yes, that too, but i wanted to post about finishing the TEC setup weeks ago. Unfortunatelly i had a "little" accident which required me to get a metal plate inserted into my hand. While it's great that i'm going to beep on airports from now on, my hand was so swallen i couldn't do...

So, as i said i wanted to test an even higher power next. I felt confident enough this prime diode wouldn't just explode like the previous ones. Luckily i was right! But first i had a little problem to solve. Ambient temperatures started changing to the point, that i was unable to just let...
