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 hour = Total lamp hour
= X*(hours used in Normal mode) + Y*(hours used in Eco mode)
X = lamp life spec of LampSave /lamp life spec of Normal mode
Y = lamp life spec of LampSave /lamp life spec of Eco mode
See
"Setting Lamp mode as Economic"
below for more information on Economic mode.
