I would expect a simple correlation is difficult or has a reasonable margin. I have been told in the past that for some products, they have been tested and sorted following production for high output without laseing. I suggest you work with the LED manufacturer's recommendation. Since the name of the game is high output, they are likely to provide specs as high as practical. It will always be important to confirm their circuit or yours is compliant with the standard under normal and fault conditions.

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. Rick Busche.
