are consumable parts. After the cumulative usage time
reaches 2000 hours, the color temperature will start to in-
crease as the usage time increases, and correct adjust-
ment will not be possible. When the cumulative usage time
reaches 2000 hours, all of the fluorescent lamps should be
simultaneously replaced with new lamps.
