1. A system for testing an effect of light exposure on a skin sample, the system comprising:
a solar simulator arranged to administer a combination of visible light (VL) and long wavelength ultraviolet radiation (UVA1) to the skin sample, the solar simulator including
a light source for generating a light beam; and
a filter combination including an interference filter for receiving the light beam and emitting a VL+UVA1 spectral output having a wavelength range of 370-700 nm with 2.0%-5% UVA1 (370-400 nm) for irradiating the skin sample.
