    Several developments designed to solve the problems found in the operation of light- and water-exposure apparatus of enclosed carbon arc type, open flame carbon arc type, and xenon arc type are described. The life of carbon rods was lengthened from 20 to 48 h in an enclosed carbon arc lamp and from 20 to 60 h in an open flame carbon arc lamp. In a xenon lamp the rate of the decrease in radiation output was reduced, doubling the life of the lamp. An automatic system for light intensity control in a xenon arc maintained a constant level of intensity throughout the test period, and an automatic system for black-panel temperature control made it possible to minimize the variation of temperature to within ±1°C. These developments increase the usefulness in operational procedure and improve the reproducibility of the test.
