Characterization of Lamps

UV lamps are often described in “watts” or “watts per inch” (“watts per cm” in metric regions). Unfortunately, this is sometimes used as if it were a specification of a UV lamp! It’s really analogous to “horsepower,” giving a general idea of the power class of a bulb, but can’t tell us anything about the performance of the lamp.

In this section, we will discuss power and spectral output, two of the most important characteristics of a lamp, outside of the optics.
