Circuit Design Notes:

Protective current-limiting resistors may be necessary to operate LEDs within the specified range.
LEDs in parallel should each have their own current-limiting resistor in series.
The driving circuit should protect the LED against reverse voltages and voltage spikes during power-up or shut-down.
The safe operating current should consider the maximum ambient temperature of the operating environment.
Prolonged reverse bias should be avoided to prevent metal migration and potential short circuits.
Precautionary Notes:
