A few months back there was a discussion on this list regarding the potential for LEDs to laze if overdriven. As I recall the issue pointed to the IEC 825-1: LED Optical Safety standard and the concern for possible testing all LEDs. The consensus was that "in general" LEDs did not pose much of a risk. My question is, without testing for luminance (or lasing) can an approximation be made which correlates to the maximum input current of an LED and the potential for lasing? I have a unique application where I want the LEDs as bright as possible but obviously want to avoid potential safety risks.
