and suggest when it is passed the lamp lifespan.
The Rack LCD series gives also a free contact and a 230 V contact for the alarms.

The system gives a more advanced control on the state of working of the lamp, permitting to
monitor on a display, istant by istant, the situation of the irradiation and the temperature of
working.
