The used lamp time is calculated internally in the following formula as the used time in each setting of [Normal], [Auto],
[ECO1] and [ECO2] in [Lamp power mode]:
Lamp runtime = (Lamp runtime of [Normal] × 60 + Lamp runtime of [Auto] × 24 + Lamp runtime of [ECO1] or [ECO2] × 45)
÷ 60

In order to estimate the lamp life, please refer to [Lamp Hours Used (Normal)] and [Lamp Hours used (ECO)] in
the [Lamp settings] menu (
Æ
page 43). [Lamp Hours Used (ECO)] is a total real time under [Auto], [ECO1] and
[ECO2] lamp power modes. Please note that they are not displayed individually.
