7.1 Life time of UVC tubes
UVC tubes have a limited life time. They are subject to a continuous aging process.
The life time of the UVC tubes is 12,000 hours under normal operating conditions
(power drop 25% ± 5% compared to the nominal UVC output of the respective UVC
source).
The effective radiation is far outside the visible range and the UVC emissions are continuously
reduced. It is therefore recommended to specify the operating conditions and the replacement
date in a maintenance plan.
Figure 8 Lifetime UVC tubes
Continuous operation increases the life time of the UVC tubes. The devices are
designed for continuous operation and should not be switched on and off often.
Frequent switching (> 3 switching operations / day) significantly accelerates the
aging process.
