Lighting Research Center Releases Report On UV Disinfection

The report from LRC, Lighting Answers: UV Disinfection Products, considers product effectiveness, radiation safety, and energy use in buildings.

The Lighting Research Center (LRC) recently released its latest publication, “Lighting Answers: UV Disinfection Products”. This online publication includes information on products that produce optical radiation at specific ultraviolet (UV) or very short visible wavelengths, designed for use in disinfecting indoor building surfaces and/or air.

Three key aspects of UV disinfection are considered throughout the document from LRC: product effectiveness, radiation safety, and energy use in buildings.

The publication is organized into a question-and-answer format. Questions were developed based on the results of a survey sent by the LRC to lighting stakeholders in June 2020. Important aspects discussed in the publication include the wavelengths of optical radiation commonly used for disinfection, key characteristics of UV disinfection products currently on the market, field measurement and assessment of UV disinfection products, and currently available codes and regulations pertaining to these products.

The publication also provides a concise guide for professionals who are considering the specification of UV disinfection products in buildings, including a discussion on selecting the dose of UV radiation needed to inactivate various types of pathogens (viruses, bacteria, or fungi) (See Figure 1).

Finally, the publication includes the results of LRC testing of 12 UV disinfection products, representing a variety of product types. This analysis includes a review of manufacturer claims of product performance and well as LRC evaluation of other key attributes of product performance. The report was sponsored by the Lighting Energy Alliance, the McClung Lighting Research Foundation, and the New York State Energy Research and Development Authority (NYSERDA).
