I have bunch of SMD LED's (mostly green and red, few white and few blue ones).. some are 0.6 some 0.8mm
The problem I have is, I have no idea what the voltage dropout is for those, what is the optimal and what is the maximal forward current, how long I can drive them with maximal forward curent .. etc etc ..
Is there any way to measure this values (Vf I can probably measure with voltmeter but how to know optimal forward current) ? Is there "standard" for SMD LED's or trial & error is the only way to go?
