2 Ecological and safe to use Always consistent results Penetrates even biofilm Nonionizing Reduces the amount of airborne particles Suitable for automatic and remote control chemicalfree UVfree Suitable for sensitive materials LED Tailor photon disinfection system deploys blue light at night or whenever the targeted space is not in use. WiSDOM AiR photon disinfection luminaires are harmless to humans and materials. The lights are typically controlled either manually (with a switch) or automatically (with a timer or a presence detector). Blue light has been shown to destroy bacteria, molds and fungi with high efficiency. Its power can be enhanced to destroy also viruses and endospores. The antimicrobial properties of blue light have been known for decades, but only the latest developments in LED technology have made disinfection with blue light a costeffective solution. The best solution for surface disinfection in the following environments: hospitals laboratories cleanrooms food industry indoor air quality issue sites nursing homes schools and day care centers dental clinics veterinary clinics grocery stores restaurants and kitchens

The ECDC conducted a study from on vectors of healthcareassociated infections in 273,753 patients in 1,149 hospitals in 29 European countries. Candida spp. (6.1%) Clostridium difficile (5.4%) Enterobacter spp. (4.2%) Proteus spp. (3.8%) Acinetobacter spp. (3.6%).

Although different microbes respond differently to blue light, it is nevertheless fatal to all of them. The antimicrobial effect of blue light on E. Coli Dark control sample WiSDOM Air In spring 2018, laboratory tests were conducted at the Turku University of Applied Sciences to determine the efficiency of LED Tailor s WiSDOM AiR photon disinfection light in the inactivation of Escherichia coli. The bacteria were plated on agar and irradiated at low intensity (0.7 mw/cm2). % Survival rate (E.Coli) The results were confirmed by conducting three separate tests, with each test utilizing three parallel samples from each point of analysis. > 99,9 % in 6 hours Time (h) Survival rate of E.coli on agar plate after 2, 4 and 6 hours.. Safe for materials and humans The Finnish Radiation and Nuclear Safety Authority (STUK) tested WiSDOM AiR photon disinfection luminaires in its laboratory on 12 April The test report shows that the radiation is nonionizing. The effects of blue light on human cells have been tested at high dosages. Even doses ten times higher than that used in LED Tailor s solutions caused no harmful or toxic changes to the cells.

4 WiSDOM AiR WA 650: WA 1200: 100 W 200 W 2,8 kg 6 kg h C MW / WW 120 IP44 / IP65 frame: aluminium light shielding: glass / PC 2 m (5x1.0 MSK) tiltable bracket (L70B50 / Ta25 C) The general luminaire model of WiSDOM AiR series, suitable for most spaces. Suitable for both ceiling and wall installation. Can be tailored to meet the requirements of different environments The disinfection system was installed three weeks ago when the stomach flu period was at its worst. The effect was astonishing the number of children with the flu remained extremely low. In our other unit, which has no disinfection system, the flu infected more than half of the children. It will be interesting to see if the system also decreases sickness in children in the long term. Päivi Isopuro, Director of Kindergarten Aurinkoleijona
