Low voltages lighting LEDs without resistor experiment
LEDs depend on resistors to protect them. However, if a low enough voltage is carefully applied to an LED, then it will limit current on it’s own. Therefore, I made the following video where I experimented with lighting resistor-less LEDs, while using my highly programmable portable power supply.

Since LEDs are a diode, they conduct easily while forward biased, and not so easily while reverse biased. However, even while forward biased, diodes block a certain voltage that varies a little bit based on how much current is passing through them. The voltage that a forward biased diode/LED blocks is called it’s forward voltage.
