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 Lamp Hour = (hours used in
Normal
mode) + 2/3*(hours used in
Economic
mode)
