Setting colour temperature
Only the light models TruLight 5000 have the Adjustable Color Temperature function
(optional). The value of the colour temperature can be manually adjusted in the
range from 3500 K up to 5000 K in steps of 500 K.
The colour temperature is set in the non-sterile area on the control panels ① on the
light head or on the corresponding optional wall-mounted control panel.
• Increasing the colour temperature:
– Press key ④ in the
Color
sec on un l the LED ③ for the required colour
temperature lights up.
• Reducing the colour temperature:
– Press key ② in the
Color
sec on un l the LED ③ for the required colour
temperature flashes up.
Mode of action of the colour temperature
The Adjustable Color Temperature function is used to increase the colour contrast in
the wound area. The visual contrast behaviour of the colour temperature is as
follows:
• For a wound area which is mainly blue in colour, a lower colour temperature
(3500 K to 4000 K) increases the colour contrast and provides a better perception
of colour differences by the operating team.
• For a wound area which is mainly red in colour, a higher colour temperature
(4000 K to 4500 K) increases the colour contrast and provides a better perception
of colour differences by the operating team.

Synchronisation of the colour temperature
The TruLight 5000 light models are equipped with a functionality for colour
temperature synchronisation.
For operating table lighting systems which consist of several lamps, the colour
temperature of the individual light heads can thereby be synchronised.
The synchronisa on se ng is made in the non-sterile area on the control panels ⑤
on the light head or on the corresponding optional wall-mounted control panel.
For activation, the colour temperature value of the light head on which
synchronisation is initiated is definitive.
• Synchronising the colour temperature:
– Press key ⑥ in the
Sync
section,
– the LED ⑦ lights up and indicates that the synchronisa on is ac vated.
– Synchronisation is deactivated if the colour temperature of a light head in the
system is changed.
