SpletIn a shortwave (SW) UVC bulb, no fluorescent coating is used, but the tube must be made of quartz or a special glass which allows shortwave UV to pass through with minimal ozone production. These are typically low … SpletThe Narva LT-T8 BLACKILIGHT Blue UV Radiators have an average life of 8,000 hours if operated with electronic warmstart ballast. The blacklight blue light colour of these tube lamps generates long wave UV light. These UV radiators feature black glass, which ensures that practically no visible light, but only UV radiation comes out of the tube ...
