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
= 1 (hours used in Economic mode) + 4/3 (hours used in normal mode)
See
"Setting Lamp mode eco function as Economic or SmartEco mode"
below for more
information on Economic mode.
The lamp hour in
Economic
mode is calculated as 3/4 of that in
Normal
mode. That is,
using the projector in
Economic
mode helps to extend the lamp hour by 1/3.
