UVA-340 is the best choice for simulating sunlight UV (photoaging)
UVA-340 is an excellent simulation of the critical short-wavelength wavelength range of the solar spectrum, ie a spectrum with a wavelength range of 295 to 360 nm. UVA-340 produces only a spectrum of UV wavelengths that can be found in sunlight.
UVB-313 for maximum accelerated testing (accelerated aging)
UVB-313 can quickly provide test results. The short-wave UV they use is more intense than the UV light waves currently found on the Earth's surface. Although these UV light, which is much shorter than the natural wavelength, can speed up the test to the greatest extent possible.
