Abstract
An apparatus for artificial weathering or lightfastness testing of samples or for simulating solar radiation, the apparatus comprises a weathering chamber, an electrodeless lamp provided in the weathering chamber and comprising a bulb filled with a composition that emits light when in a plasma state, and a radio frequency source being arranged so that it radiate a radio frequency field into the bulb to generate a luminous plasma for emitting a radiation comprising spectral emission characteristics similar to natural solar radiation.
