Measurement of Initial Characteristics
 

Measurement Criteria
 

• Measurement of Initial Characteristics is taken after discharging the lamp for 5 min. in 25 ± 2°C, 35~ 85% relative humidity and a windless environment.

• Measurement on lamp current and lamp voltage is shown.


• The measuring field of Brightness Colorimeter is 0.1° and distance between the Brightness Colorimeter and CCFL is 500 ± 5mm.

  

• Do not hold the CCFL with heat conductive material during measurement.
