What does UV lamp replacement mean in practice?
The source is replaced after the declared number of hours because the UV-C emission decreases earlier than the visible glow of the lamp.
When does it matter?
Exceeded time may leave an apparently functional device without the required disinfection dose.
Which solutions are related to it?
The date is recorded, a compatible UV lamp is used, the glass is not touched and at the same time the cleanliness of the quartz cover is checked.
