Replacing the Lamps
Lamp replacement period
It is time to replace the lamp when:
• The message "Replace the lamp." is displayed at the lower left of the
projection screen when you start projecting.
• The lamp indicator flashes orange.
Replace the lamp indicated by the flashing indicator, either lamp 1 or 2.
• The projected image gets darker or starts to deteriorate.
Caution
• The lamp replacement message is set to appear after the following time periods in
order to maintain the initial brightness and quality of the projected images.
PowerLite Pro Z8250NL/Z8255NL/Z8350WNL/Z8450WUNL/Z8455WUNL
When Power Consumption is set continually at Normal 1: About 2400 hours
When Power Consumption is set continually at ECO: About 3400 hours
PowerLite Pro Z8150NL: About 2400 hours
• Do not turn the projector on immediately after turning it off. Turning the projector
on and off frequently may shorten the life of the lamps.
• If you continue to use the lamp after the replacement period has passed, the
possibility that the lamp may explode increases. When the lamp replacement
message appears, replace the lamp with a new one as soon as possible, even if it is
still working.
• Depending on the characteristics of the lamp and the way it has been used, the lamp
may become darker or stop working before the lamp warning message appears. We
recommend that you keep a replacement lamp on hand at all times.
q
We recommend that you clean the air filter whenever you replace the lamp.

Replace the air filter if it is discolored or if a message appears even after
cleaning the air filter. s p.122
How to replace the lamp
The lamps can be replaced even when the projector is suspended from a
ceiling.
Warning
• When replacing a lamp because it has stopped illuminating, there is a possibility
that the lamp may be broken. If replacing the lamp of a projector that is installed on
the ceiling, you should always assume that the lamp is broken, and you should stand
to the side of the lamp cover, not underneath it. Remove the lamp cover gently.
