Before you try to use the light source, please read the
safety notes on page 7.
The power supply unit for the Leica L2 fibre-optic light
source is voltage-sensitive, i.e. it automatically sets
itself to the voltage available (100 to 240V) and ensures
a constant illumination level, independent of voltage
fluctuations.
The light source is switched
on and off with the brightness-
adjustment control.
Position 0: The instrument is
switched off.
To ensure that the equipment is completely disconnected
from the power supply, detach the plug of the power
supply unit.
The instrument is operating at below nominal voltage,
greatly extending the life of the halogen bulb:
– Lamp service life at level I approx. 5000 hours.
– Lamp service life at level II approx. 1000 hours.
Maximum light output.
The instrument is operating at nominal voltage.
The colour temperature is about 3200 K, and the average
bulb life about 250 hours.
