Abstract: A molecular radiation lamp containing stannous chloride SnCl2, stannous iodide SnI2, and excess tin to give thermodynamic stability against attack of the tungsten electrodes by chlorine. The lamp also contains mercury for a buffer gas and an inert gas to facilitate starting. It has been found that a first oxyhalide cycle is responsible for electrode attack and a second oxyhalide cycle is responsible for wall cleanup. For clean walls and long life, the residual oxygen level in the lamp should be reduced to the point where not enough remains for excessive electrode attack through the first oxyhalide cycle but sufficient remains for operation of the second oxyhalide cycle.
