Disconnect when not in use?

[ARFF1Tampa]

Is it a good idea to unplug this devise when the computer is on and it's not being used to save the lights (led's)? How many hours approx. do they usually last?

The IR leds themselves have a usefull lifetime of 100,000 hours.

11.4 years should just about give me time to get another one...
