This diode has it's mind set... It won't give up any time soon!
It just reached 90h this moment. Waiting for it to cool off for re-plotting.. :yh:
Excellent. Now if an 8x can survive 90+ hours at 300ma I would think that it could take 400ma for at least 10 hours, more then enough for an average use pointer.
And this is what we consider to be the worst diode of the bunch
but but but!
but it should be possible to find out how diodes degrade at their rated output? from the manufacturer, datasheets, pressreleases? i expected its simply stated in datasheets?
we dont have to identify unknown diodes. we simply try & error until we know at what output they degrade like 1% every 100 hours? (if thats what the other datasheets say about rated output)
sure, if we cant find out what the "rated degradion" is like, we are out of luck again.
perhaps the datasheet wouldnt help too much anyway? we want to know at what output the diodes survive many hours, not at what rated output they survive several thousand hours..
it was mentioned some time ago that a torture test that should be done is to turn the diode on and off repeatedly for a good long time. Since we use our lasers for short periods of time and not for long, it's the on/off cycle that ends up killing them fast. (I think it was climbak that suggested this)
I would love to see 5 sec on / 5 sec off repeat cycle. This would truly be a torture test.
However, I did not contribute to this test so havn't got a say.
