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.
