Note 1) Refer to "11. Measuring Method".
Note 2) The above test limit must be applied for initial use. Characteristics will be shifted by long period operation,
but it is not irregular phenomena. Theoretically brightness characteristics will be decreased due to color shift
due to optical components change.
