FULL stabilization:
full stabilization of the light output, distinguished by a constant brightness, which does not get reduced due to gradual decrease in the battery voltage.
SEMI stabilization:
semi-stabilization of the light output, distinguished by a reduction of the brightness with the reduction in the battery voltage.
STEP stabilization:
a stepped stabilization of the light output, distinguished by the lowering of the brightness as the battery voltage is reduced, while the driver still enables to fully stabilize the light output at the lower level.
但小弟英文不好，大致上好像是...
FULL stabilization:
完全的恆定輸出，runtime曲線維持水平直到電池用盡
