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 = 5 000 hours
When [LAMP POWER] is constantly set to [ECO] without switching to other modes = 7 000 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 71) →
[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]" × 5/7
If the time which is obtained by the above equation 5 000 hours has elapsed, the lamp turns off automatically after
approximately 10 minutes, as it will cause malfunction of the projector.
Time which is ob-
tained by the above
equation
The message is displayed for 30 seconds. If you press any
Over 4 800 hours
button within the 30 seconds, the message disappears.
If the power is turned on without replacing the lamp, the
Over 5 000 hours
power automatically turns off after approximately ten min-
utes to prevent the malfunction of the projector.
Note
f The time which is obtained by the formula for lamp replacement time "5 000 hours" is a rough guideline, but is not a
guarantee. The lamp runtime differs depending on the setting of "LAMP POWER" menu.
