Operating Life
Note1 Ta means ambient temperature.
Note2 If modules is driven by high current or at high ambient temperature & humidity
condition. The operating life will be reduced.
Note3 Operating life means brightness goes down to 50% of initial brightness. Typi-
cal operating life time is estimated data.
