Or are they saying that if u use a 10% duty cycle you can pump max 195mA through them provided your pulse width is 0.1ms?


What Paul said. Unless you like the sound of "pfft".



Word of warning to readers: I've got datasheets for LEDs that can take 180mA at 10% duty cycle, I've got datasheets for other LEDs that can only take 30mA at 10% duty cycle (ie. 20mA normal, 30mA peak).

If you don't have a proper datasheet, don't make any assumptions about what a LED can do.
No, I don't answer questions sent in private messages (but I do accept thank-you notes...)

Ok thanx guys, I think I get it now. I will keep the current at 40mA for my application and hopefully they will not blow up
