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:
Total (equivalent) lamp hour = A*(hours used in
Normal mode) + B*(hours used in Economic
mode) + 1.00*(hours used in SmartEco mode)
See
"Setting Lamp mode as Economic or SmartEco"
below for more information on Economic
mode.

Extending lamp life
The projection lamp is a consumable item. To keep the lamp life as long as possible, you
can do the following settings via the OSD menu.
Setting Lamp mode as Economic or SmartEco
Using
Economic
mode reduces system noise and power consumption by 15%. Using
SmartEco
mode reduces system noise and lamp power consumption by up to 30%. If the
Economic
or
SmartEco
mode is selected, the light output will be reduced and result in
darker projected pictures.
