Abstract
A UV lamp service life indicator device includes an indicator member including a material that degrades at a rate sufficient to track a useful life of a UV lamp, where the indicator member indicates whether the UV lamp has come to an end of its service life. The indictor device can also include a reference component that indicates whether the UV lamp has come to an end of its service life.

A UV lamp service life indicator device, comprising:
- an indicator member including a UV degradable material that degrades at a rate sufficient to track a useful life of a UV lamp,
- where the indicator member indicates a status of the useful life of the UV lamp.
A method of servicing a UV lamp, comprising:
- subjecting a degradable material of a UV lamp service life indicator device to UV radiation;
- changing a characteristic of the degradable material;
- detecting a detectable condition of the indicator device indicating a status of a useful life of the UV lamp;
- and
- changing the UV lamp with a new UV lamp.
