This paper summarizes of the lighting of the xenon-mercury variable color discharge lamp by using a transformer circuit. As a result of this research, it was proved that this method could become an effective system for practical application. The lamp is made by a glass tube of 25mm outer diameter and 1.2mm thickness, and has two pairs of external electrodes, one pair for the axial directional discharge and another pair for the radial directional discharge. Xenon gas of 3.0kPa and mercury were enclosed, and the phosphor mixture of NP105 (for Hg : blue color) and NP360 (for Xe : red color) in 1:1 weight ratio was used. The CIE chromaticity (x, y) was from (0.187, 0.095) to (0.471, 0.242), and the luminance was from 174 to 508 [cd/m^2] by changing the mixture ratio of radial and axial discharge when the lamp was operated at the clock frequency of 32kHz. In order to increase the luminance, the clock frequency was raised to 50kHz, and the CIE chromaticity (x, y) was from (0.247,0.118) to (0.403,0.205), and the luminance was over 1000 [cd/m^2] in every mixture ratio of radial and axial discharge.
