Inverter-built cold cathode sterilization lamp. Multiple lamps can be lit with a single adapter. Contributes to space-saving.

Testing Organization: Japan Food Analysis Center, Osaka Branch Test Subject: Staphylococcus epidermidis Test Results: After 30 minutes: 90.7% inactivation After 60 minutes: 99.54% inactivation After 90 minutes: 99.99% inactivation Test Chamber: 25㎥ (equivalent to 6.6 tatami mats) *These test results do not indicate effectiveness in actual usage environments.

Irradiation from a distance of 5 cm for 5 seconds > 99.99% inactivation Irradiation from a distance of 10 cm for 10 seconds > 99.94% Irradiation from a distance of 20 cm for 10 seconds > 99.44% Target: Novel coronavirus Delta variant Lamp used: Cold cathode sterilization lamp, spiral shape, 12W In an in vitro study (test tube experiment) conducted as a commissioned research by Professor Daisuke Hayasaka and Associate Professor Chuu Shimoda from the Joint Faculty of Veterinary Medicine at Yamaguchi University, it was confirmed that irradiating the Delta variant of the novel coronavirus on a petri dish from a distance of 5 cm for 5 seconds resulted in > 99.99% inactivation. Additionally, under other conditions, it was confirmed that irradiation from a distance of 10 cm for 10 seconds resulted in > 99.94%, and irradiation from a distance of 20 cm for 10 seconds resulted in > 99.44% inactivation of the same virus.
