8.13 Illumination
What can be done?
Within a certain percentage, the light output of the light source can be reduced by reducing the power slider.
Alternatively, you can enable CLO mode (Constant light output) for a constant light output over a longer period
of time.
You can only change the power output when the shutter is opened.
About CLO mode
All light sources naturally decrease their intensity over time. In order to prevent a decreasing output in a multi-
projector setup, you can activate CLO mode to make sure that the light output remains constant.
CLO mode will ensure that the projector regulates its illumination power to maintain the same level of output
light during the lifetime of the light source. This requires that the light source power is not set to 100% from the
start, but to a lower value. The lower this value is set, the longer the projector will be able to maintain the
output level.
