Lamp characteristics are related to the temperature of the arc plasma in high-pressure discharge lamps in which local temperature equilibrium in established. In this paper the relationship between radial temperature profile of the arc plasma measured by optical methods and a mathematical model for lamps is discussed. These discussions can lead to an improvement of the mathematical model after taking into account the temperature frofile. The coefficients of the mathematical model equation are determined statistically by using the simplex method. The usefulness of this improved model is discussed, comparing the simulated results With experimental results for discharge lamps operated by resistance ballast.
