[LIGHT OUTPUT] can be adjusted individually for each setting item of [OPERATING MODE].
f
In such a case when configuring multiple screens with multiple projectors, uniformity of brightness between multiple screens can be
obtained by adjusting [LIGHT OUTPUT].
Interrelation of luminance and runtime
You can use the projector with desired brightness and duration of use by combining the settings of [MAX LIGHT
OUTPUT LEVEL], [LIGHT OUTPUT], and [CONSTANT MODE] in [BRIGHTNESS CONTROL SETUP].
Interrelation of luminance and runtime is as follows. Make the settings depending on your desired duration of use
and brightness of the projected image.
Values of the luminance and runtime are rough estimations.

Note
f
Under influence of characteristics of each light source, conditions of use, installation environment, etc., the runtime may be shorter than the
estimation.
f
The duration of use is referred to as the runtime when you use the projector successively. The duration of use is an estimated duration and
is not the warranty period.
f
If the runtime exceeds 20 000 hours, replacement of the components inside the projector may be required. Consult your dealer for details.
