All LEDs eventually dim.
Running it at full brightness theoretically reduce lifespan, but in some cases (like if the brightness control is a harsh form of PWM) then full brightness might actually lengthen the life span.

LEDS are usually rated 25000-50000 hours to 70% brightness.

So that means that when i used it 25k-50k hours its at 70% bright
