A: UV-C light (which the ILLUMICIDE device uses) is capable of de-activating and/or reducing harmful bacteria, viruses, molds and other pathogenic microorganisms.
Here are test results for Staph A. and E. Coli:

The International Ultra-Violet Association is working diligently to determine UV-C's effectiveness against COVID-19. See the
IUVA Fact Sheet on COVID-19
Here's an excerpt:
UV light, specifically between 200-280nm (UVC or the germicidal range), inactivates (aka, ‘kills’) at least two other coronaviruses that are near-relatives of the COVID-19 virus: 1) SARS-CoV-1 and 2) MERS-CoV.
Here is some additional information:
Coronavirus Inactivation Doses

Background: To slow the increasing global spread of the SARS-CoV-2 virus, appropriate disinfection techniques are required. Ultraviolet radiation (UV) has a well-known antiviral effect, but measurements on the radiation dose necessary to inactivate SARS-CoV-2 have not been published so far.
Methods: Coronavirus inactivation experiments with ultraviolet light performed in the past were evaluated to determine the UV radiation dose required for a 90% virus reduction. This analysis is based on the fact that all coronaviruses have a similar structure and similar RNA strand length.
Results: The available data reveals large variations, which are apparently not caused by the coronaviruses but by the experimental conditions selected. If these are excluded as far as possible, it appears that coronaviruses are very UV sensitive. The upper limit determined for the log-reduction dose (90% reduction) is approximately 10.6 mJ/cm2 (median), while the true value is probably only 3.7 mJ/cm2 (median).
Conclusion: Since coronaviruses do not differ structurally to any great extent, the SARS-CoV-2 virus – as well as possible future mutations – will very likely be highly UV sensitive, so that common UV disinfection procedures will inactivate the new SARS-CoV-2 virus without any further modification.

SterileLight's ILLUMICIDE device outputs a range of 3,000 mJ/cm2 (at the light source) and 1,100 mJ/cm2 (from reflective surfaces) which is far higher than the above mentioned UV dosages.
