Half-life is the amount of time in hours before the LED is half (50%) as bright as when it is first turned on.

MTBF is the mean time between failures. In other words. How many of the LEDs will fail after 100K hours or 200K hours. Much of this is dependent on the heat the display operates in. The hotter the environment, the shorter the half-life
