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) +
(hours used in SmartEco mode)
Equivalent lamp hour = 1.8*(hours used in Normal mode) + 1.3*(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.
