Light source
The light source of the projector uses lasers, and has the following characteristics.
f
Depending on the operating environment temperature, the luminance of the light source will decrease.
The higher the temperature becomes, the more the luminance of the light source decreases.
f
The luminance of the light source will decrease by duration of usage.
The time until when the luminance of the light source decreases by half differs depending on the setting of the
[PROJECTOR SETUP] menu → [OPERATION SETTING] → [OPERATING MODE].
The estimated time until when the luminance of the light source decreases by half is as follows.
(The time is estimated when the [PICTURE] menu → [DYNAMIC CONTRAST] is set to [3].)
g
When [OPERATING MODE] is set to [NORMAL], [QUIET1], or [QUIET2]: Approximately 20 000 hours
g
When [OPERATING MODE] is set to [ECO]: Approximately 24 000 hours
g
When [OPERATING MODE] is set to [LONG LIFE1]: Approximately 43 000 hours
g
When [OPERATING MODE] is set to [LONG LIFE2]: Approximately 61 000 hours
g
When [OPERATING MODE] is set to [LONG LIFE3]: Approximately 87 000 hours
The luminance can be maintained as much as possible for the same runtime by setting the [PROJECTOR
SETUP] menu → [OPERATION SETTING] → [CONSTANT MODE] to [AUTO].
This time is rough estimate when the projector is used without changing the [OPERATING MODE] setting, and
will vary depending on individual difference and usage condition.
If brightness is noticeably reduced and the light source does not turn on, ask your dealer to clean inside the
projector or replace the light source unit.

Computer and external device connections

and shielded cables as well.
