Controlling the colour
temperature (optional)
The TruLight 5000 light models are equipped
with a functionality for variable colour
temperature ③. 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 ② on the
light head or on the corresponding optional
wall-mounted control panel.
• Increasing the colour temperature:
– Press key ⑦ in the
Color
section until
the LED ⑥ for the required colour
temperature lights up.
• Reducing the colour temperature:
– Press key ⑤ in the
Color
section until
the LED ⑥ for the required colour
temperature lights up.
Mode of action of the colour temperature
The variable colour 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.
For normal operations, a colour temperature
in the range 4000 K to 4500 K should be
initially selected.
