SED or Smoke Emitting Diode

This is an attempt to record the very edge to which an LED can be driven. A failed attempt.


I tried to post this as a component page, but it would not take embedded video...

The LEDs I tried are rated at 30 mA maximum. The forward voltage is between 1.9 and 2.1 V. I used a power source of 8.1 V  and a variable resistor in series that could range from 5000 to 0 Ohm.
