So... what's it gonna be, Igor? Meanwhile, we've got mad scientists hitting >750mW @450mA... :wtf:
Btw, why's this topic in off-topic???

I thought I read in the murder thread that one of the diodes was was emitting only spontaneous emissions (LED as we call it)?
Based on the curve of the diodes graphed in the 12X diode thread, and as Hemlock Mike pointed out, there seems to be 2 distinct lines showing up which might indicate 2 different diodes at 2 different efficiencies.
The lower efficiency 12Xs seem to follow a similar curve to the 8Xs you tested.
I have not seen data sheets for either the 8X or 12X diodes (do we have them?) so I would think that it might be possible that some 12X drives are using the same diodes as the 8X drives. However, I do not think this is very likely.
Exerd is testing one 12X to very high powers (over 700mW) and has about 7 minutes on this diode. Already he is noticing RAPID degradation.
My vote is to set it to 550mw. If we push to 600, and the diode dies early, we have data that isn't particularly useful. 550mw is a conservative amount, but what good would another evil smiley face diode be? The first was probably a freak accident, but I am the paranoid type. My vote is 550mw. If it performs with long life, then we could assume 600 is still reasonable with shorter life but not too short.
Well the votes have long since been in (I think) but you're still the MC here, Igor, so 430mA has my vote (too) :takeit:In any case, 550mW would require 430mA with this diode. But seeing they are surviving even higher currents for measurable (or should i say testable) amounts of time, i still think it would be a good point to test... if we can agree on a decision for the test current i can start the torture...
