Electrode diagnostics and modeling of ceramic metal halide lamps were investigated. An explicit method was used to solve the heat balance equations of a two-dimensional, rotational symmetric electrode body numerically. Near-IR radiation intensities of the electrode were measured by imaging the tungsten electrode rod on a CCD camera through a narrow band filter at 990 nm. A spot behavior in Hg-lamps with heavy electrodes is observed.
