TEXT -912 -968 Left 0 ;The model uses only one  thermal resistor element, \n the filament to case Rth. \nThe basic formula:\nTemperature = TAmbient + (TotPower-OptPower) * Rth1\nRFilament = RCOLD*(Tfilament/Tcold)^1.2\nThe ambient temperature TEMP is also included in the model.\nAll parameter interface temperatures are in degree Celsius.\n \nThe enhanced  lamp models can provide up to six control outputs.\nR: resistance  \nP: electrical power \nL: light power \nTf: temperature of filament   \nTb: temperature of bulb     *not supported\nTs: temperature of socket  *not supported
