The temperature and currently had influence with led
The led has influence on temperature and currently
Temperature effect
High temperature will cause low light output
The drift of led wavelength due to a variety of output color
Forward voltage will fall down
persistent herd for long time will cut down server time or cause luminous decay.

The currently effect
The drift of instable current due to a variety of color output
If the currently is beyond its normal range value will decrease server time.
