4.4 Replacement of the lamp
Before carrying out any intervention on the fixture, cut off all external power sources and
place appropriate work-in-progress warnings on the systems.
Wait for the discharging time (at least 5 minutes) and check using appropriate instruments
that there are no residual energies before accessing the electrical equipment.
The replacement procedure of the lamp is valid for all the light sources. Lamp lifetime depends on the actual use
conditions: working time, brightness level and number of ignitions. The lamp must be replaced when brightness
drops below 50% of the originally emitted light flow. It is suggested to replace the lamp when the light bulb reaches
80% of the working life (depending on the rated current).
Remove the upper cover of the fixture and access the lamps (see related paragraph in the chapter “ADJUSTMENTS
AND MAINTENANCE”). Disconnect and remove the burnt lamp.
