With this online tool you can calculate the number of luminaires needed to achieve the desired disinfection level on the specified surface in professional application areas. The tool delivers results by calculating the irradiance levels on working plane and by matching these levels with the required UV-C dose for deactivation of the chosen pathogens.

• The room specified by the user as well as the working plane should be as close as possible to the real room where users wish to achieve surface disinfection.
• The particular pathogen to be deactivated and the deactivation level can be chosen from the list of pathogens along with their corresponding deactivation levels.
