In the old days, while I was working on the prototype for dirt, lasers were hazardous and LED's were not. The laser hazard levels were determined by power and frequency essentially. LED's just weren't bright enough to be of concern. That has changed somewhere since the last time I had to worry about it and now there is a group of LED's that have become controlled by the FDA and medical safety standards. I want to screen potential LED candidates via component spec sheets and eliminate the potential for bringing in LED's that I have to control. Can someone give me a quick contrast between "hazardous" LED's and my non-hazardous CRT power-on type LED and or a reference so I can dig into this further. A quick word search in 60601-1 didn't find LED requirements.
