UV light is responsible for almost all photodegradation to durable materials exposed outdoors. The QUV’s fluorescent lamps simulate the critical short-wave UV and reproduce the physical property damage caused by sunlight. Several different types of UV lamps are available for different applications. Request Q-Lab Bulletin LU-8160, Choice of Lamps for application guidelines.

QUV Lamps
UVA-340 Lamps. The UVA-340 lamps give an excellent simulation of sunlight in the critical short wavelength region from 365 nm down to the solar cut-off of 295 nm.

UVB-313 Lamps. The UVB-313 lamps maximize acceleration utilizing short-wave UV that is more severe than the UV normally found at the earth’s surface. Consequently, these lamps may produce unrealistically severe results for some materials. UVB-313 lamps are most useful for QC and R&D applications, or for testing very durable materials.
