Looking for a source of information concerning safety issues of working with high intensity LEDs. I know that looking directly at the LEDs is harmful, and there is a specification that dictates how long you need to look at a light source of  known intensity before eye damage occurs. I need to find the spec and its source. I would also be interested in learning if the effects of viewing LEDs are cummulative or not. ie does looking at an LED for 30 sec give the same effect as looking at the LED for 3 sec  10 separate times. thanx.
