LM-79 testing  confirms that the LED is properly managed and run from a thermal standpoint.  Although  LEDs do not give off “forward heat”  like a traditional halogen source, they do get hot.  If they run too hot their lifespan may be shortened. Thermal management is actually the key to their long life.  Proper heat sink should be designed which controls heat and dissipates the heat away from the LED itself.  The result is a very long life.
