A stretched exponential function is used to fit the cooling curve of a tungsten filament. Fitting parameters are given for a set of tungsten filaments varying from 10 to 100 mm in length and from 0.05 to 1 mm in diameter. The instantaneous time constant of cooling and its dependence on temperature and position along the filament are discussed.
