UVB-313 UV lamp:
UVB-313 for maximum acceleration test (accelerated aging)
UVB-313 can quickly provide test results. They use shorter wavelengths of UV than are currently found on the surface of the Earth's UV waves are more intense. Although these much shorter than the natural wavelength of UV light is able to accelerate the test to the greatest extent

UVA-340 UV lamp:
UVA-340 simulates the best choice for sunlight and ultraviolet rays (photo-aging)
The UVA-340 provides excellent simulation of critical short-wave-range sunlight spectra, which are wavelengths from 295 to 360 nm. UVA-340 produces only the UV wavelengths that can be found in sunlight.
