Check the data sheet for the LED or the sellers web site.
An LED is much like any other diode.

The characteristic forward voltage drop depends on what material it is made of, and is related to the color of light it emits.

The maximum allowable current, or power handling ability, depends on the physical size and construction of the diode junction.

20mA @ 1.6V -standard red LED.

Wanted to know something else? Ask a more specific question.
