Note (1)
Lamp current is measured with current meter for high frequency as shown below. Specified
values are for a single lamp. To exceed 7.5
mA, life time accelerate drop down and if to
exceed 9.0 mA has safety problem. If current lower than 3.5 mA, CCFL would be unstable or
damaged.
Note (2)
Lamp frequency may produce interference with horizontal synchronous frequency and this
may cause ripple noise on the display. Therefore lamp frequency shall be kept away from the
horizontal synchronous frequency and its harmonics as far as possible in order to avoid
interference.
Note (3)
Lamp life time (Hr) can be defined as the time in which it continues to operate under the
condition : Ta=25±3

C, Typical IL value indicated in the above table and fL=48 kHz until the
brightness becomes less than 50%
