Iwasaki UV Lamps Demonstrate Effectiveness in Inactivating SARS-CoV-2
Iwasaki Electric conducted a joint evaluation study with Professor Hiroki Ohge of the Department of Infectious Diseases, Hiroshima University Hospital, and Professor Takemasa Sakaguchi of the Laboratory of Virology, Graduate School of Biomedical and Health Sciences, Hiroshima University, to assess the effectiveness of UV lamps used in Iwasaki products against SARS-CoV-2 (the virus responsible for COVID-19). The study confirmed a high level of virus inactivation performance.
As part of ongoing efforts to help prevent the spread of COVID-19, Iwasaki Electric continues to provide safe and reliable environmental hygiene solutions through UV-based air, surface, and water disinfection technologies.
In addition to UV lamps, Iwasaki Electric manufactures and supplies a wide range of ultraviolet light sources, including UV-LEDs, pulsed xenon lamps, and excimer lamps.
Evaluation studies are also being conducted on these ultraviolet light sources to further verify their effectiveness against SARS-CoV-2.
Test Virus
SARS-CoV-2 (COVID-19 virus)
Tested UV Lamps
UV lamps used in products such as the Airlia air disinfection systems and the Steri-EYE UV disinfection equipment.
① UV lamp used in: Airlia, Airlia compact
② UV lamp used in: Airlia plus, Airlia power, Steri-EYE
Test Method
A virus suspension was applied to plastic Petri dishes and allowed to dry. After exposure to ultraviolet radiation from each UV lamp, the recovered virus infectivity was measured using the TCID50 assay.
Test Results
Both UV lamps (① and ②) achieved greater than 99.9% inactivation of SARS-CoV-2 at a UV dose of 3 mJ/cm².
* mJ/cm² is the unit used to express the cumulative UV dose.
UV Dose (mJ/cm²) = UV Irradiance (mW/cm²) x Exposure Time (seconds)
Example Products Equipped with the Evaluated UV Lamps

Important Safety Information
- UV lamps are not intended for general illumination purposes.
- Do not expose skin directly or indirectly to UV radiation, as it may cause skin irritation or inflammation.
- Never look directly at an operating UV lamp. Avoid exposure to reflected UV radiation, as it may cause eye injury or vision impairment.
- Airlia and Steri-EYE are not medical devices.
- UV lamps contain a small amount of mercury. Handle with care and dispose of lamps in accordance with local regulations.
- Product specifications and appearance are subject to change without notice for product improvement.
