Wall-ceiling germicidal lamps operate during the absence of staff and patients. This is an effective method for disinfecting air and surfaces. The appropriate power of the direct-action germicidal lamp depends on many factors, including the shape and area of the room (mainly its height). Additionally, the degree to which the walls and objects in the room reflect light must also be considered. Important parameters include humidity, air dustiness, and microorganism resistance. Therefore, it is difficult to definitively determine how many direct-action germicidal lamps of the NBV series should be placed in a given room. Generally, it can be assumed that sufficient microbiological cleanliness can be achieved by installing in a room with a height of 2.5 to 3m: a 15W lamp for an area up to 8 m², a 2x15W lamp for an area up to 12 m², a 30W lamp for an area up to 15 m², and a 2x30W lamp for an area up to 22 m². The duration for which the direct-action germicidal lamp should operate depends on the type of room and its purpose. For example, in patient rooms, treatment rooms, or operating rooms, the lamps are turned on for 2 to 8 hours. For disinfecting a room (for instance, during breaks between procedures), this type of equipment is activated for about 15-20 minutes.
