A bullet shows the active mode.
When switching from the dual mode to the single mode the lamp with the longest runtime is switched off.
If the runtimes are equal (if the projector has always been operated in dual mode) then lamp1 is switched out.
When switching to single mode, returning to the dual mode will not be possible in the fi rst 60 seconds, Dual
in the menu is greyed out and LED1 is fl ickering, thereby preventing hot restrike which may damage the lamp.
7.5.4 Constant Light Output
Overview
• Constant Light Output Mode
• CLO Target
• Dimmer Set Position
• Linked CLO
7.5.4.1 Constant Light Output Mode
What can be done?
Constant Light Output allows to force a constant light output (set in the CLO Target ... menu) of the projector over a certain period.
This will eliminate uncontrolled light output drop caused by natural aging of the lamp. The light output is checked every 5 minutes,
if the target is not met, the lamp power is adjusted.
Setting CLO off means that the lamp will operate at constant power (no power adaptation to meet constant light output).
In the illustration below, a normal light output curve is shown over the fi rst 1000 hours, image 7-108. By using CLO and setting the
target to 60% of the maximum light output, one will be able to operate during approximately 500 hours with a constant light output,
