When to replace the lamp unit
The lamp unit is a consumable component. Since its brightness gradually decreases over time, it is necessary to
replace the lamp unit regularly.
Time for replacement
When [LAMP POWER] is constantly set to [NORMAL] without switching to other modes = 6 000 hours
When [LAMP POWER] is constantly set to [ECO] without switching to other modes = 8 000 hours
but the lamp may go off before the time above mentioned has elapsed depending on individual lamp
characteristics, usage conditions, and the installation environment. It is recommended that the Replacement lamp
unit be prepared earlier.
In order to predict the lamp replacement time, please refer to the lamp runtime displayed in [STATUS]
(
x
page 87) → [RUNTIME] → [LAMP] → [NORMAL]/[ECO]. It also can be obtained by using the following
formula. (The time which is displayed in [ECO] is the converted usage time when set to [NORMAL].)
Formula for lamp replacement time (rough estimate) = “Lamp runtime of [NORMAL]” + “Lamp runtime of
[ECO]” × 3/4
If the time which is obtained by the above equation 6 000 hours has elapsed, the lamp turns off automatically after
approximately 10 minutes, as it will cause malfunction of the projector.
