I have some LEDs that I'd like to get max brightness out of them for a short pulse. They will serve a safety purpose, to grab attention of human eye.
So now I'm wondering, is there a pulse width that is known to reach full brightness as far as the eye sees? I played around with different pulse widths, and it seems at about 50ms the light is perceived as 'fully on'. Any longer, it doesn't get brighter. Any shorter, and perceived brightness decreases.
And juts how high current a pulse can be? I don't have a full spec sheet, I just know the LED is rated at 1A 12v forward. As a general rule of thumb, what is the ratio between duty cycle and current? If it's 1A continuous, as a general rule of thumb, can it be said that it could be driven at 10A at 100ms pulse?
