hello everyone around 2 months ago i bought 3 of those 1dollar 5-20mw 405nm diodes that ebay has, there was no info at all,no datasheet or any recommended current so first i had to find the pinout.
after some testing i found that those are case negative,i made a power test with my psu and things got abit weirder,it passed the 20mw by far and while i was incresing the current i didnt noticed any foldback.
here is the quick testing video:

sorry for the bad quality,my phone isnt that great :angel:
after the video i did pushed it up to 150ma and gave 232mw!! :eek:

my question is what the hell are they selling on ebay?are this supposed to be a 5-20mw diode?probably i could push it more as it didnt fold back at all.
anyone else ever tried those cheap diodes? this looks like to me a stronger diode...
