Note 1 : The voltage ( r.m.s. ) to maintain the electric discharge of the lamp. It is measured after lighting
for 3 minutes .
Note 2 : The current ( r.m.s. ) to flow through the lamp with the electric discharge. It is measured after
lighting for 3 minutes.
Note 3 : The voltage at starting the electric discharge when the voltage is increased gradually from 0V.
Note 4 : Surface Luminance is specified by the initial data of luminance measured at the center of display
surface after 20 minutes power on. ( All ON pattern )
Note 5 : CFL life is defined as the time for which the initial luminance is attenuated by 50% of the
luminance value. Average Life representes the time elapsed at the point of time when the residual
ratio becomes below 50% when plural lamps are lighted in comparison with the definition of life
mentioned above.
