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= 20/9 * (hours used in Normal mode) + 5/3 * (hours
used in Eco mode) + 20/13 * (hours used in Sm1 * (hours used in LampSave)
See
"Setting Lamp mode eco function as Economic or SmartEco mode"
below for more information on Economic mode.
The lamp hour in Economic, SmartEco and LampSave is calculated shorter of that in
Normal mode. That is, using the projector in Economic, SmartEco or LampSave mode
helps to extend the lamp hour.
