Lamp information
Getting to know the lamp hour
When the projector is in operation, the duration (in hours) of lamp usage is automatically calculated by
the built-in timer. The method of calculating the equivalent lamp hour is as follows:
Lamp Usage Time = (hours used in
Normal
mode) + (hours used in
Economic
mode)
Total (equivalent) lamp hour = 1.0 x (hours used in
Normal
mode) + 1.0 x (hours used in
Economic
mode)
To obtain the lamp hour information:
1. Go to
SYSTEM SETUP: ADVANCED
>
Lamp Settings
and press
OK
. The
Lamp Settings
page appears.
2. Press
to select
Lamp Timer
and press
OK
. The
Lamp Timer
information is displayed.
You can also get the lamp hour information on the

Description
Normal
Provides full lamp brightness
Economic
Lowers brightness to extend the lamp life and decreases the fan noise
• The apparent brightness of the projected image will vary depending on the ambient lighting conditions, selected
input signal contrast/brightness settings, and is directly proportional to projection distance.
• The lamp brightness will decline over time and may vary within the lamp manufacturers specifications. This is
normal and expected behavior.
