Fluorescent Devices

Fluorescent UV lamps, similar in mechanical and electrical characteristics to those used for residential and commercial lighting, have been developed with specific spectral distributions. These sources are incorporated into fluorescent UV condensation devices such as the UV2000. These devices may be used in tests that vary light/dark cycles, temperature, condensing humidity, water sprays and irradiance control.

Tests using fluorescent lamps are useful for relative rank comparisons between materials under specific conditions, but the comparison to service lifetime performance or correlation to outdoor exposures may not be valid. The best use of the UV lamps is for general screening tests, such as checking for gross formulation errors with an artificially harsh exposure.
