Surface Disinfecting UV Light, BIL-UVL

UV Light for Surface Disinfection Applications Dental offices Hospital, surgery rooms, veterinary clinics Schools, daycare, kindergarten, university / colleague class rooms for kids, young students and adults Sport clubs, fitness centers Physiotherapy, acupuncture, massage centers Beauty salons, nail, hair, laser removal salons Office placess Playgrounds and toy rooms Home, children room Wavelengths The lamp house uses one or two wavelengths , both at ultraviolet range, depending on the model: Ultraviolet: the ozone-free ultraviolet sterilization lamp can only sterilize the place and surfaces that are exposed to UV light rays. The places and areas which are blocked by direct exposing of the light will not be affected.  A standard wavelength of UV for disinfection is 185nm. Ozone ultraviolet: the UV sterilization lamp with both UV and Ozone is a double sterilization technology.  This allows disinfection of surfaces which are not exposed directly to the UV light. Disinfection Test Results The product was tested under standard protocols for sterilization. Test procedure was as following Electrical: The product was placed on the non-conductive turntable 0.8m above the ground at a chamber. Spectrum analyzer was set in the peak detection. Conducted emission, radiated emission and radiated electromagnetic disturbance as well as immunity of Equipment Under Test (EUT) were determined, according EN61195. Biological: according to standards of EN IEC 55015:2019, EN IEC 61000-3-2:2019, EN 61000-3-3: 2013 A1:2019, EN 61547:2009.

Viable is defined as the ability to multiply via binary fission under the controlled conditions. Counting with colony-forming units requires culturing the microbes and counts only viable cells, in contrast with microscopic examination which counts all cells, living or dead. The visual appearance of a colony in a cell culture requires significant growth, and when counting colonies it is uncertain if the colony arose from one cell or a group of cells. Expressing results as colony-forming units does not distinguish.   Warning: Do not stay near by the UV light when it is turned on. Make sure you leave the space during the 15 seconds delay time. Do not use the room light or day light during the lamp usage time. Do not look at the light when the light is on. Ozone light may generate some unpleasant smelling. make sure you use the ventilation on during the device usage.
