Application: Artificial weathering

The weather testing process of paints, films and materials can be greatly accelerated through the use of specially designed weathering chambers. Most of the commercialized devices are using gas discharge lamps to simulate/accelerate the effect of sunlight. Special fluorescent, xenon and metal halide lamps depending on the system manufacture all are utilized to simulate the suns radiation. The xenon arc source, when used in conjunction with appropriate filters, is generally regarded as giving the closest approximation to natural sunlight that can be obtained in the laboratory
