It's not necessarily only the current which can hurt the LED nevertheless the voltage in addition. The supply voltage need to not be greater than the forward running voltage. Or mur led else, it might problems the junction. A normal LED includes a voltage ranking as much as 4.0 V in addition to a present ranking of around 30mA.
As opposed to some electrical products that includes a variety of different pins LEDs are uncomplicated since they only have to have two wires or pins. On the list of wires with a LED is favourable and on the list of wires is destructive.
